Eggplants planted in early autumn cannot bear fruit, and the flowering and fruiting period of eggplant is June-August.
Growth habit of eggplant
temperature
Eggplant likes high temperature, the optimum temperature for seed germination is 25 -30 degrees Celsius, and the optimum temperature for seedling development is 25 -30 degrees Celsius during the day, 15 degrees Celsius -20 degrees Celsius at night, which is lower than 15 degrees Celsius, causing slow growth and flowering. /kloc-metabolic disorder below 0/0℃.
illuminate
Eggplant needs high-intensity light time. Under the condition of long sunshine and high intensity, eggplant grows vigorously, with good flower bud quality, high fruit yield and good coloring.
moisture
Eggplant needs less water before molding, but it needs more water after rapid growth, and it needs the most water before and after harvest, so it is necessary to fully meet the water demand. Eggplant likes water and is afraid of it. When the soil is wet and poorly ventilated, it is easy to cause root retting, and the air humidity is high, which is easy to cause diseases.
land
It is suitable for cultivation in soil with rich organic matter and strong water and fertilizer conservation ability. Eggplant has a large demand for nitrogen fertilizer, which delays flower bud differentiation and obviously reduces the number of flowers, especially in full bloom. If nitrogen is insufficient, more short flowers will appear and plants will not develop well. Under the condition of low nitrogen fertilizer level, the effect of phosphorus fertilizer is not obvious, and the absorption of potassium increases sharply in the later stage.
How to make eggplant planted in Guilin in August and September bear fruit and overwinter should pay attention to the following aspects:
First, cultivate strong seedlings.
1, preparation of nutrient soil
Before sowing, prepare 30-35% of high-quality decomposed organic fertilizer, 0.2% of multi-component compound fertilizer and 0.2% of carbendazim, and mix them evenly for later use. A seedbed of 15m2 should be prepared for every 667m2 planting area, and the prepared nutrient soil should be spread on the seedbed with a thickness of 8 ~ 10 cm. In recent two years, seedling raising in nutrient pots has reduced the slow seedling stage caused by transplanting and promoted the normal growth of seedlings.
2. Variety selection
The purpose of early-maturing cultivation of eggplant in greenhouse is to obtain high-quality commercial eggplant with early maturity and high yield. This variety requires cold tolerance, low light tolerance, compact plant type, 7-8 nodes of flowering, early maturity and high yield, good fruit shape and strong disease resistance, which is suitable for local planting.
3, soaking seeds to accelerate germination
Sowing will be carried out in late July. Firstly, the seeds are treated as follows: soaked in 500 times of 50% carbendazim wettable powder for 2-3 hours; Dry seeds are treated for 3 days under the condition of constant temperature and dry heat at 70℃, and then germinate and sow; Soak the seeds in warm water at 55℃ 1.5 ~ 20 minutes, then soak the seeds in warm water to accelerate germination, and sow when 60% of the seeds begin to appear white in 4 ~ 5 days.
Step 4: Sowing.
Before sowing, water the seedbed, then spread 1cm fine soil to fill it and spread it evenly. After sowing, cover with 1cm fine soil, spread with plastic film to keep moisture, if the temperature is too high, cover with sunshade net, and remove the plastic film and sunshade net when about 70% seeds break the soil. Nursery seedlings in nutrient pots, point 1 ~ 2 seeds per pot with a depth of 1cm, and water them in time after the point to ensure the normal emergence of seeds.
5, timely seedling division
When the seedlings have 2 ~ 3 true leaves, they can be divided into seedlings, and the row spacing can be maintained at 10cm× 15cm. For ditching planting, water the soles of the feet first, and add 0.2% carbendazim when watering after covering the soil to prevent seedling diseases. After seedling separation, the temperature is controlled at 23 ~ 28℃ during the day and 65438 05℃ at night. Before planting, the seedlings were sprayed twice with 400 times potassium dihydrogen phosphate solution to cultivate strong seedlings.
Second, transplantation and planting.
1, deep tillage and fertilization
It needs to be turned twice, the first time is 30cm deep, and it can be fertilized after leveling. Every 667m2, 4000kg of decomposed organic fertilizer, 40kg of diammonium phosphate, 30kg of potassium sulfate and 50kg of calcium superphosphate can be applied, and then the second turn should be shallow and the fertilizer should be turned evenly. In areas with serious diseases, plastic film mulching can be used to increase the ground temperature as soon as possible in high temperature weather, and high-temperature sterilization can be carried out for 1 ~ 3 days to kill verticillium dahliae and other germs in the soil.
2. Ridge planting
Soil preparation: the width of the border is 1. 1m, the depth of the ditch is 0.2m, two rows are planted in each border, the spacing between plants is 30cm, the planting density should be controlled at about 4050 plants per 667m2, and sufficient planting water should be poured. After the seedling is delayed, a small ditch is opened in the middle of the ridge to lay a drip irrigation pipeline, which is covered with plastic film after repair.
Three. Matters needing attention in greenhouse
1, temperature and humidity control
When eggplant is cultivated in winter, the optimum temperature is 28 ~ 30℃, the lowest temperature is 17.5℃, and the highest temperature is 40℃. If the temperature is lower than 65438 05℃, the pollen tube elongation almost stops. If the temperature is below 15℃ at night, although the temperature is high during the day, the pollen tube grows fast and slow, and the purpose of fertilization can not be achieved. Therefore, the temperature in the shed should be controlled at 28 ~ 30℃ during the day and at 17.5 ~ 20℃ at night. When the temperature exceeds 30℃, it should be ventilated in time. When the temperature drops to 20℃, the vent should be closed, and when the temperature drops to 65438 05℃, cover or straw mat should be used to keep warm. In the month of June 5438+February, the management mainly focuses on heat preservation. Especially when the temperature drops greatly on cloudy days and snows, fluorescent lamps are needed to fill the light and ignite the floor heating to raise the temperature. The quilt or straw mat should be uncovered late and covered early, and the dust on the shed surface should be cleaned up to increase the light and prevent freezing injury. Pay attention to timely ventilation and reduce humidity, and the relative humidity of air should be 50%-60%.
2, the whole branch hanging branches
The side branches left under the eggplant should be smoothed as soon as possible, and only four strong branches are left on the eggplant, and the branches should be hung in time. Remove the old leaves below the eggplant at the bottom in time to strengthen ventilation and light transmission.
3, point flowers to protect fruit
In winter, the temperature is low, and the eggplant falls seriously, so it needs some flowers to protect the fruit. Usually in the early flowering period. 30mg/kg of 2,4-D can be coated on the flower stalk and then marked with white powder to avoid repetition. The concentration of 2,4-D used should also be adjusted appropriately with the temperature, and the concentration should be high at low temperature and low at high temperature.
4. Fertilizer and water management
Eggplant has a large single leaf area and a lot of water transpiration, so it is generally necessary to maintain 80% soil relative humidity. When the soil moisture is insufficient, plants grow slowly, even cause flowering, and the fruit surface is rough and the quality is poor. Therefore, eggplant should be watered and fertilized as little as possible before sitting in front of the door, so as to control the vegetative growth and promote the early entry into the fruiting period. Watering when the plant begins to swell, especially in the full fruit stage, is the key period of fertilizer and water demand. Topdressing with 7kg urea and NPK compound fertilizer 15kg per 667m2 with water. Water 1 time every week during the harvest period, and topdressing every two batches of fruits 1 time. In addition, due to the special greenhouse environment and insufficient light, it is necessary to replenish light in time. Before sitting in the greenhouse, use fluorescent lamp to replenish light 1 hour every day, and after sitting, replenish light for 2 hours every day. At the same time, the amount of carbon dioxide in greenhouse is seriously insufficient, which affects the photosynthesis of eggplant and reduces the yield of eggplant. So it is necessary to produce carbon dioxide steam fertilizer regularly every morning. After sunrise in the morning, according to the principle that dilute sulfuric acid reacts with ammonium bicarbonate to generate carbon dioxide, the concentration of carbon dioxide in the greenhouse is increased by using the reaction of the generator, and the photosynthetic products are also increased, so as to achieve the purpose of high yield and good harvest.
5, pest control
(1) major diseases
The main diseases are eggplant verticillium wilt, eggplant cotton blight and gray mold. Verticillium wilt of eggplant is a common destructive disease, which seriously affects the quality and yield of eggplant. Verticillium wilt can be controlled by root irrigation with 50%DT for 3-5 times, or by spraying with 500 times thiophanate-methyl solution or 500 times Baitongtong solution. Tomato cotton blight is a fungal disease, which mainly harms fruits. Select locally cultivated disease-resistant varieties for prevention and control, and determine reasonable planting density according to different varieties. The rotation system has been implemented for more than 3 years, and the previous crops should be beans or onions and garlic, so as to avoid continuous cropping with solanaceae and cucurbitaceae crops. In addition, attention should be paid to reducing the humidity in the greenhouse and reducing the occurrence of diseases. Secondly, chemical prevention should be carried out: spray protection should be carried out before the onset to prevent the occurrence of diseases, and prevention should be carried out immediately after the onset. After cotton wilt occurs, 90% ethyl aluminum phosphate 500 times solution or 86.2% copper master 1000 times solution 1 time can be sprayed every 7- 10 days to prevent large water temperature irrigation. It can be prevented and treated by using 500 times solution of junliling and 600 times solution of nongliling. 50% carbendazim can be used for soil disinfection for cataplexy, 75% carbendazim can be used for soil disinfection after onset, and 600 times of 75% carbendazim can be sprayed after onset.
(2) Main pests
The main pests of eggplant are aphids, red spiders and white mites. Aphids can be sprayed with 1000% primary clear solution 1000 times, and red spiders can be controlled with 0/500 times solution of mites/kloc-or 2000 times solution of propargite. Spraying 10% imidacloprid 2000 times can control acaroid mites.
Is lemon suitable for planting in Xing 'an, Guilin? Lemon is suitable for planting in Xing 'an, Guilin. Lemon is warm, resistant to shade, not cold, and also afraid of heat. Therefore, it is suitable for planting in subtropical areas with warm winter and cool summer. The suitable annual average temperature of lemon is 17- 19℃, the annual effective accumulated temperature (≥ 10℃) is above 5500℃, the monthly average temperature of 1 is 6-8℃, and the extreme minimum temperature is above -3℃. The annual rainfall exceeds 1000 mm and the annual sunshine hours exceed 1000 hours. Lemon is suitable for planting on warm gentle slope, with deep soil layer and good drainage. The most suitable soil pH value of lemon is between 5.5 and 7.0. Lemon plants grow faster, 3-6 meters high, and need a lot of fertilizer. They sprout, blossom and bear fruit many times a year. Due to good management, the yield often varies greatly.
cultivation techniques
Garden construction and planting
Ping ba Jian yuan
When building lemon orchards with paddy fields, ditches should be raised along the slopes to dry the fields. After drying the soil in the coming year, a steamed bun-shaped mound with a height of 40-50 cm and a bottom diameter of 1m will be erected at a fixed point according to the planting row spacing.
Slope landscape construction
The problems of soil fertility and soil and water conservation can be solved by building contour terraces, contour ditches or fish scale pits in sloping fields. Contour terraces are suitable for slopes of 100-25 degrees, contour ditches are suitable for slopes of 6- 100 degrees and slopes with deep soil layers, and fish scale pits are suitable for steep slopes and complex terrain where it is difficult to build horizontal terraces or contour ditches.
Lemon colonization
Planting density-generally 3 m× 4 m, 55 plants per mu is appropriate. Planting period is generally in spring and autumn, and transplanting in autumn should be carried out in September-65438+10. Before planting, dig planting holes (ditches) with specifications of 60 cm× 60 cm× 60 cm, and apply 30-50 kg of organic fertilizer, 0.5- 1 kg of calcium superphosphate or more than 20 kg of decomposed human and animal manure to each hole, mix the fertilizer and soil evenly, and cover the soil to make a planting pier with a height of 20 cm. When planting, remove the grafting film of the seedlings, trim the damaged roots, and cut off the long main roots and tender late autumn leaves. Make a small nest on the planting pier, put the seedlings, trim the roots while covering the soil, gently lift the roots of the seedlings, and gently press the soil to make the roots closely connected with the soil. The planting depth should be consistent with the mud mark in the seedling stage, the root neck should be exposed from the ground, the root water should be poured thoroughly, and covered with straw, straw, green manure or plastic film for heat preservation and moisture retention.
Post-factory management
It takes about half a month for seedlings to survive after planting, so it is advisable to water them frequently without topdressing during this half a month. After surviving, Qin Ying should check to ensure that the soil is wet and not touching the ground, and promote the growth of roots and new buds. After a small number of new buds grow, manure cleaning water can be applied. [8]
Young tree management
soil management
Every winter in leisure season, combined with shallow ploughing and soil cultivation, 40-60 cm long and 60-80 cm deep fertilization holes 1-2 are dug outward at the drip line of the tree crown, and compost (or manure) 100kg/m2 is applied, and mixed with the soil evenly, which is beneficial to cultivating the developed absorption roots of young trees and enhancing the nutrient absorption function of trees.
Fertilizer and water management
Young trees-apply fertilizer 5- 10 times a year to be diligent and thin. The type of fertilizer is mainly available nitrogen fertilizer, with phosphorus fertilizer, potassium fertilizer and human and animal manure. From the germination of spring shoots in March to the emergence of autumn shoots in September, 30% decomposed human and animal manure was applied every month/kloc-0. Annual young lemon trees are usually applied with 80g of nitrogen, 40g of phosphorus and 30g of potassium every year, and the annual increase is about 10g. 2-4-year-old young trees, the fertilization period is concentrated before each shoot. Fertilize 5-6 times a year, and spray 3-4 times on the leaves at the tender branch stage.
Young tree shaping
The dry height of lemon is about 40-50 cm. When the grafted seedlings germinate in spring or mature in summer, pick the core at the full bud of the branch tip 40 cm above the ground to promote 4-6 new shoots to sprout at 25-40 cm to form branches. If the new shoots are not ideal and there are few branches, the buds can be smeared 1-2 times to promote the trunk to send new branches. When the branches are mature, select the strong branches from the upper part as the first main branch, leave them 20-25 cm long, cut off the top part, and use the rest as auxiliary branches.
Adult tree management
Fertilizer and water management
The principle of fertilization is to apply spring fertilizer as soon as possible, stabilize fruit fertilizer as appropriate, apply strong fruit fertilizer again and supplement fruit picking fertilizer, and generally apply fertilizer 3-4 times a year. The amount of fertilization is determined according to the number of fruiting plants and the supply of soil fertilizer. If fruit trees produce 30 kilograms of fresh lemons, each plant needs to apply 0.3 kilograms of nitrogen, 0.2 kilograms of phosphorus and 0.2 kilograms of potassium a year. Fertilization methods can be carried out in holes, ditches or radial ditches. The type of lemon fertilization should be the combination of farmyard manure and chemical fertilizer, with farmyard manure as the main fertilizer. Apply spring flower fertilizer when the spring shoots germinate in February and March. Give priority to with quick-acting chemical fertilizer, with organic fertilizer. Weak trees and plants with many flowers should be applied more, while strong trees or plants with few flowers should be applied less or not. Generally, the amount of nitrogen fertilizer applied accounts for 10%- 15% of the whole year. Apply stable fruit fertilizer from flower withering to fruit swelling in May. Foliar spraying of 0.3% urea is mostly used, and the fertilization amount accounts for about 5% of the whole year. Autumn shoots germinate in July and August, and strong fruit fertilizer is applied when the fruit expands. Available nitrogen, phosphorus and potassium fertilizer are mainly used, combined with the application of organic fertilizer, and the fertilization method adopts hole (ditch) fertilization. The amount of fertilization should be large, with nitrogen fertilizer accounting for 40% and phosphorus and potassium fertilizer accounting for 50% of the whole year. Apply fruit fertilizer in June165438+1October after fruit picking. Organic fertilizer is mainly used, with a small amount of chemical fertilizer applied, and the method of rotary fertilizer is mostly deep application by opening holes (ditches). The application rate of nitrogen fertilizer accounts for 40% of the whole year, and the application rate of phosphorus and potassium fertilizer accounts for the whole. More than 40% in 7 years. Results The key of water management of trees is to ensure sufficient water supply in spring shoot emergence and young fruit period. In case of drought, water should be supplied immediately. If the water source is insufficient, water-saving point irrigation can be used. That is, a jar-shaped cave with a big top and a small bottom, a depth of 40-50 cm and a diameter of 30-40 cm is dug 30 cm and 3-4 directions outside the drip line of the tree crown, and the hole is filled with decomposed straw and green manure, and then a layer of organic matter and soil is compacted until the hole is 10 cm, and the hole is filled with water, and then filled with soil. In addition, the lemon tree tray can be covered with film all year round to prevent water evaporation.
Reasonable pruning
Lemon pruning can be carried out all year round, but mainly in winter and spring, supplemented by pruning in growing season. The first fruiting tree pruning is mainly based on light thinning and long planting, and attention should be paid to cultivating excellent fruiting mother branches to keep enough flowers every year and increase yield. With the increase of tree age and yield, the amount of pruning will increase year by year. In pruning, summer pruning is more used, combined with tree cultivation, auxiliary main branches and side branches are continued to be configured, extended branches are shortened, and long branches disturbing the tree are deleted as much as possible. In spring and autumn, leave weak or moderate vegetative branches as fruiting mother branches to ensure that there are enough flowers and fruits in the coming year, so that the vegetative center of trees can turn to reproductive growth in time.
Pruning of fruit trees: in summer, the buds are removed and the seeds are removed, and in winter, the pruning amount is increased year by year, so as to keep the growth balance of new shoots and fruits as much as possible and prevent fruit bearing in different years. For the fruiting branch group, the spring and autumn shoots are pruned by rotating pressure, and 8- 10 leaves are left for coring as soon as possible. When the summer buds germinate, they are wiped and put out, and the buds without buds are repeatedly wiped. Until the middle and late July, a large number of short and strong autumn buds are drained. These autumn shoots will become excellent mother branches in the coming year after thinning out the tender branches that are too dense and inappropriate. After the fruit bears, the auxiliary branches on the crown are sparse year by year. After the drooping branches bear fruit, the drooping parts are easier to grow, and the drooping parts at the top can be cut off year by year to raise the position of the branches and continue to bear fruit. For large straight branches with more tops, we can deal with them according to the principle that strong trees are sparse, middle trees are sparse, weak trees are sparse, and strong trees are short. For the adult trees that were neglected in shaping and pruning in the early stage, or the upper part of the crown was strong and the lower part was weak, pruning methods such as thinning branches, sawing large branches, serious retraction, opening the skylight, cutting and riding branches should be taken as appropriate to reduce the crown, restore the tree potential as soon as possible, and form the yield.
Guo Hua management
From July to August last year, according to the age, tree vigor, fruit bearing capacity, rainfall and other conditions of lemon trees, autumn shoots were released uniformly to form good fruiting mother branches, and at the same time, branches and leaves were protected to prevent pests and diseases such as leaf miner. After the autumn shoots of 5438+00- 1 1 are fully mature in June, the soil should be loosened and roots should be cut off moderately to control the growth of winter shoots and promote the differentiation of flower buds.
Take timely measures to protect the fruit after the lemon tree withers. 1. Young fruit stalks can be coated with 250× 10-6 gibberellin (g A3)+400× 10-6 cytokinin, or sprayed with 50× 10-6 gibberellin+Aiduo liquid medicine, or sprayed with most liquid medicine. The second is to apply fruit-stabilizing fertilizer from flower withering to fruit swelling in May, and spray 0.3% urea and 0.2% potassium dihydrogen phosphate solution on the crown. 7 days 1 time, 3 times in a row, can improve the fruit setting rate. Third, beekeeping in orchards, creating a good pollination environment is also conducive to improving the fruit setting rate. Fourth, quick-acting chemical fertilizers should not be applied in May-July, so as to reduce the sprouting of summer shoots and consume the nutrition of trees. At the same time, summer shoots should be smoothed in time to alleviate the contradiction between flower and fruit growth and new shoots. Fifth, when it rains during flowering, shake the trees in time to remove the accumulated water on the petals to prevent flower retting. If there are too many fruits in the lemon tree, the fruits of the plants with too many fruits can be thinned in time from late June to early July after the second physiological fruit drop, so as to ensure the large size and high quality of the fruits and prevent the years. According to the principle of "sparse but not sparse, there are good and bad", sparse and decrypt the collected fruits, small fruits and deformed fruits. Leave 30-35 leaves and one fruit is appropriate.
Fruit bagging
The paper bag is a special paper bag for lemon, with black inside and yellow outside, and the length and width are 20cm x 15.5cm ... Choose orchards or plants with good tree potential and high management level, and choose lemon fruits with good appearance, no pests and diseases and a diameter of 30-40 cm for bagging. Lemons and spring flowers are best bagged in early July. Before bagging, all tree crowns must be thoroughly sprayed with fungicides (Opal, Viral Quick Clean, Sheng Da or Scofield) and pesticides (Mirex or Insect Mites), and special attention should be paid to the prevention and control of rust ticks, scale insects and mites. If the diseases and insect pests are serious, it can be sprayed 1 time every 3 days, and bagged after the medicine is dry.
choose
Fruits should reach the required maturity before harvest. Generally speaking, the transverse diameter of lemon fruit is not less than 50 mm, and the color of lemon fruit changes from dark green to light green, even slightly light green. Flowers will be picked in late June from 65438+ 10 to mid-June 165438+ 10, in late February from 65438+February to early October of the following year 10, and in June and July of the following year. The method of double cutting is always used when picking fruits. The first is to cut off the fruit and its branches. The second is to cut off the sepals, cut off the fruit stalks and cut the fruit stalks flat. Fruit picking should be done from top to bottom and from outside to inside. Don't climb branches and pull fruits at heights or far away, but use fruit ladders to help pick fruits, so as not to strain the pedicels of fruits. Gently put the fruit into the fruit basket, and when it is 90% full, replace the empty basket. From fruit picking baskets to fruit boxes (laundry lists), we must also handle them carefully. Handle with care during transportation. Primary selection should be conducted before storage, and damaged fruits, fallen fruits and pest fruits must be placed separately. Don't pile fruit anywhere after harvest, and don't spend the night in the open air.
Can Luoshenhua be planted in Guilin?
Roselle, also known as Luoshenhua, Luokehong, Shanqie, etc. , a plant of Panicum in Malvaceae, is widely distributed in tropical and subtropical regions. Originated in the west and India, it is cultivated in Zhejiang, Guangxi, Guizhou, Yunnan and Shanghai. Roselle plants 1.5 ~ 2 meters high, with lavender stems, erect stems and many branches. Leaves alternate. It blooms in summer and autumn, with long flowering period, cup-shaped calyx and purple and yellow corolla. Every flowering period, red, green and yellow alternate with each other, which is very beautiful and has the reputation of "plant ruby". Calyx (fresh or dry) has the functions of lowering blood pressure, resisting scurvy, diuresis, relieving bronchitis and cough.
Cultivation method of luoshenhua
Luoshen flower likes warm and bright light, and the temperature below 12℃ is not conducive to seed germination and seedling growth, and it is not resistant to frost. Different strains have different responses to sunshine intensity. In subtropics, it is a short-day summer crop, which blooms in late summer. In Guangdong and Gannan, the initial flowering period is in August, and the seeds are all mature in 65438+February. The number of fruit per plant is positively correlated with the number of branches, so adopting varieties with many branches, fertilizing and topping are all measures to promote branches, which are all helpful to increase the number of fruit. Strong adaptability, drought tolerance, good barren tolerance, sandy or clayey soil can grow, suitable for replanting in flat or sloping land of red soil and latosol, but soil with deep soil layer, good drainage and irrigation and fertile soil is conducive to high yield.
The land needs ploughing, harrowing, subdivision and ridging, and can be planted when the climate is stable above 15℃ in March and April. Soak the seeds in warm water at 40℃ for 6 hours before sowing. Hole sowing, hole spacing 120* 100cm, about 8250-9000 holes per hectare, 3-5 seeds per hole. The 1000-grain weight is 40-50g, the sowing amount is1.5-2.25kg/ha, and the soil is covered about 2cm after sowing. Manure or compost 15-22.5 t/ha should be applied to each mu of base fertilizer, and appropriate amount of phosphorus and potassium fertilizer should be applied. Topdressing can be combined with intertillage weeding and soil tillage. About one month after the first emergence, nitrogen fertilizer was mainly applied at the second closing of buds, and then nitrogen and potassium mixed fertilizer was applied again at the flowering and fruiting stage. Roselle has the hazards of cutworm, blind stinkbug, leafhopper, damping-off disease and leaf shrinking disease. When sowing, spray 30-37.5 kg carbofuran per hectare, and catch it after emergence to prevent the harm of cutworms. Cicadas and small buds sprayed with dimethoate solution can also avoid the occurrence of leaf shrinkage disease, and damping-off disease can be treated by spraying with 0.2% thiophanate solution. In addition, ditch cleaning and drainage should be done to avoid waterlogging. In case of high temperature and early drying in flowering period, irrigation should be done in time to fight drought.
Application value of luoshenhua
Because of abundant sunshine and strong ultraviolet rays, it is planted in unpolluted wilderness in mountainous areas. The appearance of the product is full of particles, the petals are thick, purple and black, the melt water is bright and fresh, the gas is slightly fragrant and sour, and it is rich in nutrients such as vitamin C, elderberry glycoside and citric acid. The calyx of Roselle is delicious, rich in protein, organic acids, vitamin C, various amino acids, and a large number of natural vitamins and minerals needed by human body, such as iron, calcium and phosphorus. Its composition analysis is as follows: 5.7 grams of reducing sugar; Protein 2.37 grams; Pectin19.8g; 3.3 grams of malic acid; Tannin1.09g; Anthocyanin14.5g; Vitamin 89 mg/100 g contains aspartic acid, glutamic acid, proline, glycine, alanine, lysine, arginine, etc. 17 kinds of amino acids, anthocyanins, polyphenols, furfural, hydroxymethylfurfural, especially Vc- ascorbic acid with remarkable antioxidant function. These components have the effects of calming the liver, reducing fire, clearing away heat and diminishing inflammation, promoting fluid production to quench thirst, lowering blood pressure and reducing fat, refreshing the mind and calming the nerves, and scavenging free radicals. Among them, furoic acid is considered to have certain curative effect on heart disease, hypertension and arteriosclerosis, and can reduce cholesterol and triglyceride; Other components also have spasmolytic effect on intestinal muscle and uterine muscle, and also have anthelmintic effect, which can promote bile secretion and reduce blood drug concentration and intestinal wall peristalsis. Roselle not only has the above medical and health care functions, but also is a food with good color, fragrance and taste. The pure natural healthy drink produced by it is a rare natural drink. Roselle is slightly fragrant and slightly acidic, containing vitamin C, elderberry, citric acid and other nutrients, which is beneficial to regulating and balancing blood lipids, promoting calcium absorption, promoting children's development and promoting digestion. Has the effects of cooling, detoxicating, diuresis and lowering blood pressure. No toxicity.
The calyx of Luoshen flower is juicy and can extract natural food pigments. The calyx of Luoshenhua can also be used as medicine, which is sour in taste and cold in nature, and has the effects of clearing heat and relieving summer heat, diuresis and lowering blood pressure, beauty and freckle removal, detoxification and hangover relief. Modern research shows that roselle contains flavonoids, protocatechuic acid, anthocyanins, isoflavones and rich chemical components such as amino acids, vitamins, sugars, organic acids and inorganic salts, which can lower cholesterol and triglycerides, inhibit the oxidation of low-density lipoprotein, inhibit platelet aggregation, reduce thrombosis, alleviate atherosclerosis and effectively prevent the occurrence of cardiovascular diseases. In addition, roselle also has the function of protecting liver and resisting cancer. Therefore, Luoshenhua is a good natural health care drug.
Can Guilin plant pig excrement, beans and honey? Guilin can grow pig excrement bean honey, which is suitable for hanging vines in greenhouses. Cultivate about 2000 plants in the greenhouse, hang the main vines, and leave melons with more than 4-5 leaves without spraying melon seeds. Increase the temperature difference between day and night during fruit setting, and properly control nitrogen fertilizer and irrigation to prevent excessive growth from affecting fruit setting. Leave 3-4 melons per plant in the first crop, sit on them at the same time, and expand at the same time, so that the fruits are neat and consistent. Leave 1 leaf after fruit setting, and remove all growing points on the vine. Generally, when the main vine grows to 25-30 real leaves about 40 cm from the top of the shed, it will be picked to promote the control of melon seedlings. Generally, no melon will be left at the waist node of 10-20, so go to the vine in time. When the plant is weak, 1 leaf can be left on the vine. When the eggs of 1 crops are large, and the embryos of vines produced in the upper nodes are easy to sit, 2-3 melons should be left in the second crop, and the unfruitful vines should be picked as soon as possible, leaving 1 growth points at the top without pinching. In the later stage, the shed film is removed, and 2-3 fruits are left on the sun vine to bear the third crop.
Pay attention to pruning and pinching after the dew evaporates on sunny days, so as to help the wound heal as soon as possible and prevent infection. It is best to use scissors for pruning, and prepare a wet towel soaked with drugs such as 75% chlorothalonil 200 times solution, and wipe the scissors once after cutting a tree to prevent cross infection.
How to get off at Guilin North Station or Guilin West Station from downtown Guilin to Yangshuo?
landway
1. From the South Railway Station, that is, Guilin Railway Station: After leaving the South Railway Station, walk a few hundred meters to the north, and you will arrive at the Guilin Bus Terminal on Zhongshan South Road. You can buy tickets at the station. Different models have different fares, ranging from 25 to 35 yuan. It runs every 20 minutes from 7 am to 9 pm. It is 64 kilometers from the bus terminal to the north station of Dacunmen in Yangshuo, about 1.5 hours. If it exceeds 265438+ 0 pm, there is a shuttle bus to Yangshuo, which is privately operated and the fare is expensive. If you come to Guilin in the tourist season such as holidays, it is recommended to buy tickets at the ticket window of the bus station before getting on the bus, because some drivers are very dark. You get on the bus first, and when the bus leaves the bus stop, he will ask for a price, and people in 50 yuan, 40 yuan will ask for money.

In addition, there is a direct bus from Guilin North Station to Yangshuo, which seems to be operated by a travel agency in 50 yuan. I don't know the specific departure time

Swim the Lijiang River. There are two ways: one is to take a tour boat on the Lijiang River, which is about 83 kilometers long and the lowest fare is 2 10 yuan per person, including Chinese food. From 9: 00 to 9: 30 in the morning, I boarded the boat from the Pearl River Pier and went downstream. The journey takes about 4-5 hours and arrives at Longtoushan Pier in Yangshuo at about 2: 30 pm. This is operated by Guilin Tourism Co., Ltd., which is very formal.
The other is to take a bamboo raft and swim the Lijiang River with an electric motor. The journey is from Di Yang to Xingping, about 18km. Buy a ticket at the ticket office of Lijiang Scenic Area in Di Yang Township and swim on the bamboo raft. The retail price of a bamboo raft is 2 16 yuan, which can seat four people. If there are less than four people, it will cost so much money. If you swim only half way, that is, from Di Yang to JiuMa Huashan, you can take four people at the retail price of a bamboo raft 1 18 yuan. The ticket office sells tickets on bamboo rafts. Normally, as soon as you arrive at Di Yang Pier, someone will sell you a bamboo raft tour privately. They are all sold per person, ranging from 90 yuan to 150 yuan per person. To remind you, Di Yang itself is open all day, but the drifting time is usually: 7: 00- 10: 30, 12: 00- 17: 00, which is because ships only need to pass by, 10: 30-65438. The bamboo raft ticket sold at the ticket office is to take a bamboo raft from Di Yang to Xingping to visit the Lijiang River. If you just swim to JiuMa Huashan, you can take sightseeing bus to Xingping Ancient Town for free with your ticket. And starting from Xingping, you have to take a bus to Yangshuo. Mind you, if you don't buy a ticket at the box office and make a counter-offer with a private person, and the counter-offer is very strong, the bamboo raft union is very angry, and may just take you to see the yellow cloth reflective area, which is the background of 20 yuan, and then dump you.
You can visit the Lijiang River in official website, a scenic spot of Lijiang River in Guilin, China, or you can buy a boat ticket to visit the Lijiang River on this website.
