Second, land preparation and ditching. Look at the soil moisture before planting. If the soil moisture is not good, irrigation canal can be considered, and the period of soil moisture should be 7 ~ 10 days before planting. Potato planting is generally double ridge and furrow planting, and large rows of 50 cm and small rows of 40 cm can be used when furrowing.
Third, sowing and mulching. The vernal equinox to Qingming is the best period. It should be specially mentioned here that virus-free potatoes can be sown early in advance and completed before the vernal equinox, and the spacing between plants can be controlled at 20 cm. Before sowing, spray 1: 10000 times of octanoic acid water along the ditch to prevent underground pests. Organic fertilizer can be directly sprinkled in the ditch or during soil preparation; Fertilizer can be placed in the ditch or spread between seed blocks (be careful not to touch the seed blocks directly). When sowing, there are two ways to put the seed blocks into the ditch: one is that the seed buds are facing down, and the potatoes grown in this way grow in strong roots, and the potatoes are few and large, but the seedlings are 2 ~ 3 days late; Another method is that the seed buds are facing up. The potato planted by this method has short roots, small but many potatoes, and seedling emergence is 2 ~ 3 days earlier. After planting, soil is taken from both sides of the big row to cover the space of the potato ditch and the small row, covered with microfilm and compacted.
Fourth, the emergence of fresh air and seedling management. After Tomb-Sweeping Day, the seedlings were exposed about 20 days after sowing. At this time, the microfilm can be broken at the seedling flushing place to prevent steaming the seedlings. When the seedlings grow to the height of 10 cm, the film around the seedlings should be compacted with soil to prevent water from pouring on the grass. Potatoes should not be watered at the early stage of growth, and then watered after seeing flowers. If there is no rain, you can water it once every 10 day, generally 2 ~ 3 times to ripen, and stop watering before harvest 10 day. Control pests such as aphids or thrips at seedling stage.
Fifth, rational fertilization. Potatoes like to use farmyard manure, and it is advisable to use 4000 ~ 5000 kg per 666.7 square meters. At the same time, in the rational application of chemical fertilizers, nitrogen, phosphorus and potassium should be used together. Potatoes need a lot of potassium, and the scientific and reasonable ratio of NPK fertilizer is1.85:1:2.1. Potatoes like to absorb nitrogen according to their state, and the absorption ratio of sulfur is more. According to the experiment, every 1 kg of potassium sulfate can increase the potato yield 100 ~ 150 kg.
Potato tuber is a cold-resistant vegetable, and its suitable storage temperature is 0-4℃. Because of the high temperature and humidity in the deep well kiln, the seeds stored in it are easy to germinate, which leads to the loss of nutrients in the mother block and weak germination potential. Using ditch storage method, because the external temperature is erratic, the storage ditch is too deep, which is easy to suffer from heat damage, leading to potato germination or rot, and too shallow is easy to suffer from freezing damage and lose the value of seeds. Therefore, it is an ideal storage method to use idle houses for winter storage. The method is as follows:
2. Winter: Sorting the seed potatoes, sorting out the diseased and disabled potato pieces, putting the robust potato pieces into nylon bags, each bag is 20-30kg, and stacking them in idle houses. Pile height 1.5-2.0m, but the pile must be far away from the four walls and keep a distance of more than 30 cm to prevent low temperature. Then put the water in a basin or bowl in the center of the house. After the solar term in beginning of winter, the temperature dropped. When there are signs of freezing on the water surface, cover the quilt to keep warm. Hang a thermometer in the room to adjust the thickness of the quilt according to the temperature display. At the same time, in the deep winter season, hang curtains on doors and windows to prevent the cold wind from attacking. This method has the advantages of low investment, easy temperature control and less seed loss.
How to manage wild berries in spring and strengthen strawberry management in spring can make strawberries grow vigorously, bear early fruits and have excellent quality, which is the key to win high yield. Special attention should be paid to the following measures:
1, uncover the seedlings in time. With the increase of temperature, it is necessary to gradually remove the overwintering and cold-proof mulch at the right time.
2. intertillage and loosen the soil. After spring, intertillage should be done in time to weed, promote growth and eliminate weeds.
3. Cut off the old leaves. After the strawberry begins to grow, it is necessary to cut off the old leaves and diseased leaves in time to improve the ventilation and light transmission between plants and reduce the humidity in the field.
4. Top dressing in time. After a winter dormancy period, with the increase of temperature in spring, the growth gradually accelerated. In order to increase the number of effective flowers and improve the fruit setting rate, it is necessary to topdressing in time before flowering.
5. Reasonable irrigation. Strawberries have a great demand for water, and in humid areas, a short drought will also reduce production. Therefore, at the same time of topdressing, irrigation and drought resistance should be combined, and drainage should be timely in case of heavy irrigation and rainy season to prevent waterlogging.
6. Sparse flowers and buds. After budding, thin the fine buds to reduce the consumption of nutrients and let the nutrients supply the buds that bloom first.
7. Control pests and diseases. In rainy season, we must pay special attention to ditch cleaning and waterlogging elimination, and spray chemicals in time for protection. ?
How to Manage Wogan Wogan in Spring is a hybrid of "Si" orange and "Danxi" red orange, which belongs to a late-maturing hybrid orange variety.
The following are the main cultivation techniques for reference-
Tufan
Geranium requires fertile soil and good drainage. Potted soil can be humus soil, chaff ash and garden soil, each 1/3, and a small amount of calcium superphosphate can be added to mix.
water
Geranium is drought-tolerant and afraid of water accumulation. Therefore, in the process of growth, water should be properly controlled. Too much watering and too much water in the basin soil will cause overgrowth or root rot. When blooming vigorously in spring and autumn, you can water more appropriately, but you should also keep the basin soil moist. In winter, the temperature is low and plants grow slowly, so water them as little as possible.
Fertilize soil or land
In cultivation, in addition to applying sufficient base fertilizer, in the growing season, especially in the flowering period, 1 diluted liquid fertilizer can be applied every 7- 10 days. It is best to dilute it with decomposed livestock manure and water, or to fertilize it with decomposed cake. 3-5 days before fertilization, less or no watering, watering when the pot soil is dry, is more conducive to root absorption.
illuminate
Geranium is native to South Africa and likes sunny, warm and well-ventilated environment. When the light is not too strong in spring and early summer, you can put the flowerpot in a well-lit place to receive enough light. But in the hot season of midsummer and early autumn, it should be placed in a cool place to avoid direct sunlight, otherwise it will burn branches and leaves.
decrease
for
Let plants become beautiful and bloom more. If this plant grows too vigorously in spring, it can be thinned and pruned. Cut off the residual flowers and over-dense branches in time after flowering. During the dormant period, 1 pruning was also carried out, and the withered and old leaves were cut off, and the branches were thinned and stopped.
Cut the long branches short to prepare for the new branches to continue to bloom after dormancy. In addition, geranium itself has a special smell and rarely suffers from pests. So there's no need to take precautions.
How to manage bees in China in spring 1 and strengthen heat preservation? In early spring, the temperature is low, the temperature difference between day and night is large, and there are often cold currents and frost. If the heat preservation is not good, bees will eat a lot of honey to maintain the temperature needed for the development of larvae and increase the activity, so that the overwintering bees will die prematurely because of overwork, which will not only lead to excessive consumption of feed, but also lead to the decline of bees in spring, and even freeze the larvae and pupae seriously. The main methods to strengthen heat preservation in spring are: removing redundant nests and spleens to make the number of bees dense, so that each nest and spleen is covered with bees. With the increase of temperature and the development of population potential, the density can be reduced appropriately in order not to affect the expansion of spawning circle. Fill the space in the box with thermal insulation materials, change the sunshine in time, improve and maintain the temperature in the nest. The box seam and the screen window part are pasted tightly with paper or mud. It is best to keep the weak groups below the middle group potential in a double-group box, that is, the two groups are kept together in a nest box, separated by partitions, and enter and exit the nest door respectively, so that they can keep warm against each other. The largest egg rings must appear on both sides of the door, and the two groups of egg rings form a unified whole. Because of its good heat preservation, it can speed up reproduction. Adjust the nest door according to the temperature change, and narrow it appropriately in spring, so that bees can go out to excrete and fly in windless weather above 8℃. Don't open the door in the middle of the hive in spring, but open it to the side. When the weather is fine, as long as the worker bees are not crowded and flying around, the nest door will gradually enlarge in the morning and gradually shrink in the afternoon. Unpacking inspection should be as little as possible, and must be carried out quickly at sunny, warm and windless noon to reduce heat loss in the box. Beekeepers should observe carefully outside the box in early spring, especially when excreting and flying, and judge whether the bee colony overwinters normally from the phenomena of worker bee flying, excreting and collecting water. If you find problems such as losing the king, lack of water and honey, you should deal with them in time. When most bees have flown out of the nest, we can only open the box at noon when the temperature is above 10℃ to check the honey in the box, the number of bees and the spawning situation of the queen bee. Move lightly and quickly. When the temperature reaches 14℃ and there are some honey sources outside, a comprehensive unpacking inspection can be carried out, and then different feeding management measures can be taken according to the situation of each group. Remove the outer packaging when appropriate. According to the group situation and temperature, gradually dismantle the outer packaging or heat preservation, starting from the top, then around, and finally starting from the bottom of the box; Withdraw the strong group first, then withdraw the weak group. The insulation in the box should be gradually removed with the expansion of the hive. 2. Reward feeding Appropriate reward feeding can play the role of queen bee laying eggs in spring, which is a way to promote the development of bee colonies. But reward feeding should be carried out when there is a certain amount of honey in the nest. In early spring, there should be 0.5 kg of honey in each nest of spleen. If honey is insufficient, it should be supplemented at one time and then rewarded with a small amount. It's best to start when there is a small amount of powder honey source outside, and stop when there is a cold wave, so as to avoid freezing the worker bees when they fly out. Reward feeding should be less and frequent, otherwise too much honey stored in the nest will limit the queen bee from laying eggs. In early spring, after the bee colony excretes and flies, it is necessary to replenish the pollen spleen in time, so that each frame of bees has100 ~150g of pollen, and the insufficient bees are fed with honey candy cakes or other pollen substitutes. In spring, the bees should always be supplied with drinking water, because the queen bee has begun to lay eggs and the worker bees need water to feed their larvae. Generally, one end of the cotton swab is put in the reservoir, and the other end is dragged to the front of the nest, or dipped in foam plastic and placed in front of the nest for bees to get water. 3. Enlarging the egg circle and adjusting the size of the egg circle of spleen and spleen queen have a great relationship with the proliferation speed of bee colony. Beekeepers often exchange the queen's nest and spleen filled with eggs back and forth, so that the egg circle quickly expands to the whole frame. If the back is covered with honey, or the spawning ring is restricted by the outer ring, cut the honey cover with a sharp knife scalded with boiling water. The method is to cut from front to back or from inside to outside, so that bees can move the stored honey to the outer edge of the nest and spleen to expand the spawning circle. When it comes to the third cell of the spleen, egg circles are often two big and one small, and the small one can be turned to the middle. When there is too much honey stored on the nest and spleen, it should be properly separated. The separation of honey should be carried out at a temperature above 65438 05℃, and the spleen should not be placed outside the box for too long. After taking the above measures, the spleen area of individual bee colonies can not be expanded, which may be due to the poor oviposition ability of queen bees. Two groups of such bees can be merged into a double queen bee colony, and the queen bee can be replaced later. The spleens of these groups can also be exchanged with the spleens of large-area strong groups to give full play to the feeding ability of these groups. However, in early spring, if the weak colony can't expand the spawning circle due to poor heat preservation and feeding ability, it is advisable to replace the egg worm spleen of the weak colony with empty spleen to let the queen bee continue to lay eggs, and then draw the spleen with young bees from the strong colony to the weak colony. This method of helping the weak first and then helping the weak with the strong is also a method to expand the egg circle and promote balanced development. 3 ~ 4 weeks after the egg circle is enlarged, new bees leave the house one after another, and the old bees are gradually eliminated. The number of bees in the nest is almost the same as that in early spring, but the quality is greatly improved, and the bee colony has entered the development stage. At this time, the temperature rises, the early nectar plants have blossomed, and the queen bee lays eggs faster. At this time, the empty nest spleen can be added appropriately, so that the spleen is slightly more than the bee. At the beginning, I added a spleen cover that had been used for one or two years. Empty spleen should be added between honey spleen and secondary spleen, which is the outside of secondary spleen. When there is a good honey powder source outside, new spleen or half spleen can be added, and empty spleen can be added in the middle of secondary spleen. When bees collect a large amount of honey powder, they can add a nest base frame to let bees secrete wax and make the spleen lay eggs. Spleen was added four or five times, and there were more spleen than bees. Under the condition of good heat preservation, 50% bees on each spleen are enough. If the hive is not expanded, the number of bees will always be dense, which will cause the bees to distribute heat. 4. Control the craze of bee distribution. In spring, when the bee colony develops to a certain extent, when there are 7-8 Italian bees and 4-5 China bees, there will be bee separation. When the queen bee platform is blocked, the female bee's abdomen contracts, and the amount of eggs laid drops obviously, which is a sign of bee separation. Worker bees walk slowly before bee separation, and the queen bees stop laying eggs, which is not conducive to the full play of the potential of bees and the utilization of honey powder sources, especially in the main honey flow period, which will disperse the potential of bees and affect honey collection. Improving the breeding of improved varieties and strengthening feeding management can prevent and control the occurrence of bee craze: selecting improved varieties and replacing new kings. In the artificial breeding of queen bees, we should choose bees that don't like to divide bees and can maintain a strong population as the population and feeding population. About half a month before the honey flow every year, Lao Wang is replaced by a new king. Proper control of population potential during breeding period. When the bee colony grows and the number of young bees increases greatly, it can be raised in stages and batches to cover the spleen and organize or expand new bee colonies. Gather honey early, and gather honey frequently. Collecting honey stored in nests is effective for preventing and controlling bee fever. Strong bees adopt the method of continuous production of royal jelly, and make full use of the feeding ability of worker bees, which can effectively avoid bee separation. Eliminate bad spleen, actively build spleen, get rid of old, irregular and irregular bad spleen as soon as possible, build spleen on the basis and expand spawning circle. Male bee pupae and natural queen bee platform are often cut off. Replenish the spleen in time, enlarge the door and the bee path, improve the ventilation of the hive, and keep the bee colony in a positive state all the time. Bee colonies suffering from bee fever should be treated as soon as possible. In addition to cutting off the queen bee platform, the first thing is to add egg spleen, remove all the blocked spleen in the nest, and transfer the new weak group of egg spleen, so that a box of bees has an egg spleen, which will inhibit the bees from sorting and heating because of heavy feeding work. The second is to add empty spleen, hang all the sub-spleen or cover spleen in the group and replace it with empty spleen and a part of the nest base frame. Third, exchange beehives with vulnerable groups to reduce the number of bees and group potential. Raise the king early and carry out planned grouping. For a better natural platform, bees can also be divided.
How to manage tea gardens in spring Key points of tea garden management in spring
1. Shallow tillage before and after spring tea cultivation in tea garden is 1 time. Shallow tillage before spring tea is generally carried out in March; Shallow tillage after spring tea is carried out from late May to early June.
2. Before topdressing, the amount of fertilizer applied to spring tea in tea garden is generally 100 kg per mu, with 300 kg of rapeseed cake as base fertilizer and urea 100 kg as topdressing. At the same time, spraying 800 times of new high-fat film thinner on the leaves to improve the absorption and utilization of fertilizer efficiency of crops, and cutting crops to meet the needs of tea tree growth and famous tea production.
Third, the early pruning of spring tea In today's vigorous promotion of early harvesting of famous and excellent tea, mature tea gardens are generally not pruned, because once tea trees are pruned, the germination of tea buds will be delayed. However, the pruning in the early stage of spring tea will be postponed until after the spring tea harvest. The pruning degree should be based on the growth intensity and aging degree of tea trees, and four methods should be adopted: light pruning, deep pruning, heavy pruning and surface pruning. For the newly developed young tea gardens with excellent asexual varieties in recent years, plastic pruning is an important means to cultivate the crown, especially for the tea gardens in famous tea bases. On the basis of shaping and pruning, supplemented by topping, a flat section can be quickly cultivated, which lays a good foundation for rapid and high yield. The first pruning is carried out when the tea seedlings are transplanted and planted. The main branches are cut off from the ground 15 ~ 20 cm with pruning shears to reduce the evaporation of water while shaping. In the first year of planting, although seedling protection was the main method, 1 grain of Zhuangganling was added to every 100 kg of liquid, and it was sprayed on the leaves after stirring and dissolving, with good effect, once every 7- 10 days. It can make the stems of tea trees stout, the leaves stout, the leaves fresh and tender, the plants luxuriant and the natural flavor rich. At the same time, it can improve the disaster resistance, reduce the dosage of pesticides and fertilizers, and reduce the residual poison. Generally, 0/000 kg grass or 2500 kg fresh grass per mu/kloc is better, but backbone branches should also be cultivated. The second pruning is carried out from the end of February to the beginning of March in the second year after planting. The height varies according to different tea varieties, and the pruning is 30 ~ 35 cm from the ground. The third pruning should be carried out in the spring of the third year after planting, and the height should be 45 ~ 50 cm above the ground.
How to manage 1, soil preparation and fertilization in potato field should choose sandy loam with rich soil, deep soil layer, loose soil layer, good air permeability and slight acidity. Before sowing, the stubble should be cleaned up, and the depth of tillage should reach 20 cm. Combined with ploughing, 2000 kg/mu of decomposed organic fertilizer was applied, and more than 20 kg of compound fertilizer was applied according to soil moisture (the ratio of nitrogen, phosphorus and potassium was 1:0.5:2).
2. Seed potato treatment: select suitable fine varieties and accelerate germination. Seed potato can be sown under scattered light and kept at 15-20℃, and planted directly after short and strong buds are accelerated; Seed dressing with plant ash, chlorothalonil and new high-fat film before sowing can promote the wound healing as soon as possible, reduce rotten seeds and increase potassium to prevent diseases.
3, reasonable close planting, timely sowing, spraying a new high-fat film on the surface after planting, keeping warm and moisturizing, preventing soil hardening and improving the emergence rate. After emergence, intertillage should be done in time, mainly weeding and loosening the soil, and a small amount of soil should be cultivated from the roots of seedlings. At the same time, spraying new high-fat film can prevent bacterial infection, improve the ability to resist natural disasters, improve the intensity of photosynthesis and protect the vigorous growth of rice seedlings.
4. In field management, timely loosening soil, ridging, watering, intertillage weeding and rational fertilization should be carried out. At the same time, before the potato blooms, the tuber forms an expansion period, and the timely spraying of Diguo Zhuangdiling can effectively control the overgrowth of surface branches and leaves, accelerate the ultra-rapid expansion of underground tubers, enhance the ability to resist pests and diseases, and ensure the high quality, high efficiency and bumper harvest of potatoes.
5. Control pests and diseases. Apply phoxim 3-4 bottles/mu to control underground pests when sowing or before potato production, and cooperate with spraying new high-fat film to improve the drug effect; At the same time, according to the requirements of plant protection, spraying targeted chemicals and spraying 800 times of new high-fat film can kill aphids, ladybugs, early blight, late blight and other pests and consolidate the effect.
How to manage cowpea in vegetable greenhouse in spring? Cowpea is not suitable for continuous cropping. It is best to choose a field that does not grow legumes for 3 years. Cowpea cultivated in greenhouse has a long growth period, high yield and large fertilizer demand, so base fertilizer should be applied again. Apply base fertilizer before soil preparation, and apply 5000 kg of fully decomposed organic fertilizer, 50 kg of ternary compound fertilizer, 20-30 kg of calcium superphosphate and 0/5 kg of potassium sulfate/kloc per mu. Early ploughing and deep ploughing should be carried out in cowpea field to realize fine soil preparation, so as to improve soil water and fertilizer conservation capacity, improve soil structure and improve soil fertility. Deep ploughing, raking and leveling, making a high ridge with a width of 1.2m, and covering it with plastic film. Covering with plastic film can increase low temperature and promote root growth. 3. Cultivating strong seedlings In order to ensure the robustness of seedlings, the method of transplanting seedlings is generally adopted in greenhouse cultivation. Seedling in greenhouse or greenhouse ripens 7 ~ 10 days earlier than direct seeding. The seedling raising method is as follows:
3. 1 seedbed preparation: firstly, prepare nutrient soil, use 6 parts of fertile garden soil without leguminous vegetables, add 4 parts of fully decomposed organic fertilizer, add 0. 1% ternary compound fertilizer, and mix well. Put the nutrient soil into a nutrient bowl with a diameter of 8 cm and lay it flat on the seedbed. 3.2 Timely sowing: Early cowpea cultivation in greenhouse and early seedling raising are generally sown around March 5th. Before sowing, carefully select seeds, eliminate damaged, germinated, immature and incomplete seeds, and select seeds that are large, full, neat in size, uniform in color and without mechanical damage. Sun seed 1-2 days. Choose to sow in sunny days. Before sowing, soak the seedbed with water, sow 2-3 seeds in each pot, cover with 1.5 cm fine soil, buckle the small arch shed, cover the grass grid at night, and cover the grass grid in the morning and evening.
3.3 Seedling management: Before emergence, maintain the high temperature of 26 ~ 28℃ during the day and18 ~ 20℃ at night; After emergence, the temperature is reduced to 20 ~ 25℃ during the day and to 13 ~ 15℃ at night. With the increase of temperature, the wind resistance will gradually increase. Hardening seedlings at low temperature within 7 ~ 10 days before sowing, 15 ~ 20℃ during the day and 10 ~ 15℃ at night. 20 ~ 25 days after sowing, when the first pair of true leaves spread out, it is the suitable seedling age for transplanting.
How to manage spring cherry trees in the first half of March, before germination, we should pay attention to the following points:
1. Prune cherries before germination in winter. Young trees are mainly shaped, and trees over 3-4 years old are mainly thinned and delayed, and attention should be paid to opening the bottom corners of backbone branches to alleviate the polar growth of cherries, promote short branches and promote flower bud differentiation. Cultivation, regeneration and rejuvenation of fruiting branches should be the main stage of full fruit, and the number and distribution of flower buds should be adjusted to facilitate high and stable yield.
Older trees should be scraped and peeled. Scraped old and warped skins were collected, taken out of the orchard and burned.
3. Cherry trees with more fruits should be topdressing with 1 times compound fertilizer, which can be applied in radial furrow, and sprinkler irrigation can be used if quick-acting chemical fertilizer is applied.
4. After fertilization, the germinated water should be watered 1 time, which is especially important in North China.
5. Boiling and spraying 1 3-5 Baume sulfur mixture in the whole garden can prevent and control pests and diseases, significantly reduce the harm of pests and diseases, and have good control effect on scale insects, brown beetles, longicorn beetles and deciduous diseases.
6. In the park where the grass is seriously covered by scale insects, you can pile a 40 cm beach under the tree to prevent the trees above from being hurt. The first fruit cherry in spring is flowering. How to manage cherry trees in spring should pay attention to the following four measures:
First, pay attention to matching fertilization.
Cherry, like other plants, needs a lot of mineral elements, such as nitrogen, phosphorus, potassium, calcium, magnesium, iron, boron and zinc. Without these elements, the big cherry can't grow and develop normally, and even have corresponding element deficiency.
& lt/FONT & gt； Second, the disease tree treatment
The treatment of diseased trees includes: ① cutting off diseased branches and treating diseased trees with dead branches; At the same time, clean the roots of dead branches in the same direction, cut off rotten roots, and coat carbendazim and mancozeb (both 400-600 times). At the same time, the pit was enlarged to 100cm2, with a depth of 60cm, and filled with 20cm soil mixed fertilizer and 20cm new soil to prepare for planting trees again next year. (3) Check the branches of fruit trees and remove the egg lumps on the branches.
Third, tree pruning and shaping.
After defoliation, the branches of trees are clear, which is an ideal period for pruning and shaping. Branches can be pulled properly according to production needs. At the same time, cut off the inner cavity, the upper branches on the back and the cross branches without flower buds from the roots (after cutting, color them to prevent drying shrinkage). After picking the fruit, combine with summer pruning to remove the inner chamber and upper branches that do not need to be preserved. Combine the root soil, straighten the tree basin and dig the drainage ditch.
Four, timely watering spring water, spraying fungicides in time.
In recent years, there is little rain and snow in winter and the drought is serious. It is suggested that the orchard be watered once (combined with fertilization). Watering every half month (before flowering) can not only alleviate the drought, but also reduce the ground temperature, thus delaying the flowering time of fruit trees. Spray 5-degree sulfur mixture or 1: 2.5: 200 BE solution in time to disinfect trees. By "painting white", the absorption of ultraviolet rays from the sun by trees can be better reduced, and the excessive temperature rise of trees can be delayed, so that the flowering time can be delayed, and the blooming fruit trees can be placed in a more suitable pollination temperature environment, thus improving the fruit setting rate.
How to manage orchids in spring
Orchid management in spring pays attention to moistening and thinning.
In the management of orchids in spring, we should pay attention to the word "moist", "transparent" and "rare", or "scattered". Spring does not come out: pay attention to the cold!
The water content of the material in the basin should be wet, but it must be thoroughly poured, and it should not be excessively wet because it needs to be wet. This is a no-no!
When watering, don't water the seedlings to avoid wet buds. When soaking, the water must be one or two centimeters lower than the material level in the pot to avoid soaking buds. This is a no-no!
Apply less fertilizer every time, but apply it fully, not indiscriminately, to prevent seedling injury and bud injury! Be sure to return to the water to prevent root rot!
There should be plenty of sunshine, but it will still disperse. Don't be careless when the climate highlights high temperature! Spring does not come out: pay attention to the cold! In spring, the earth's atmosphere rises and everything begins to wake up and grow. People have a physiological proverb: spring covers autumn without covering it. In spring, we should guard against strong winds and cold spring! But on sunny days and when there is no wind or breeze, you can open the window to get some air.
Rule number two
For the glass of the blue shed, the method of opening when the sun comes out and closing when the sun goes down. Due to the large temperature difference between day and night in early spring, opening the window as soon as the sun comes out in the morning to let in fresh air and warm wind is conducive to the recovery and growth of orchids. Closing the window when the sun goes down can prevent the orchid from being hurt by the cold at night.
Orchids should be classified and managed, and the flowering period should be limited;
Fertilize the orchids in the pot at the end of the year;
Put the non-flowering orchids together, leave her alone, but let them see more sunshine, keep the orchid pot moist, and let her blossom as soon as possible. Fertilize after all flowers bloom every 7-65,438+00 days (the fertilization concentration can be slightly higher, because new roots have grown and new grass has not come out, which will not hurt roots and buds); Apply bactericide once a month in early spring, once or twice a month in late spring, and apply insecticide once a month after late spring to kill insects and insects. Bluegrass metabolism, yellow leaves should be trimmed in time.
Three rules
Winter passed, spring came back, and everything was completely new. After the return of Dujiangyan in spring, all kinds of animals and plants woke up in the spring thunder. At this time, I would like to remind my friends of orchids that orchids in your have to wait for pests, such as scale insects, red spiders and small snails. No matter whether diseases are found or not, around your orchid garden, including walls, floors, orchid plants, orchid pots and flower stands. The vernal equinox, that is, March 2 1 22 in the solar calendar, is the peak period of germ growth of various plants, and the end of the dormancy period of orchids is also the best time to change pots and plant them separately. Adjust sunshine, temperature, ventilation, etc. In the case of uneven cold and hot in the blue room and uneven air temperature, the best state is achieved. The spring buds of orchids cultivated in greenhouses are half long, but those cultivated in mountainous areas are covered with water moss. This time is the best time to sterilize. The new buds are half long, but the spring buds cultivated in the mountains are covered with water moss. It is the best time for sterilization and disinfection. Therefore, it is necessary to prevent the occurrence of bacterial diseases and black spot diseases caused by pests and immature buds in advance. Qingming: April 5-6 in the solar calendar. At this time, it is the rainy season. It rained continuously and the wind was biting. At this time, orchids have sprouted new buds one after another, and the leaves and stems of the spring buds that have already opened leaves have already stretched out quickly. The temperature will rise tomorrow, and sometimes there will still be cold wind blowing. Where orchids grow, the indoor humidity of orchids is high, so special attention should be paid to watering and fertilization, especially sterilization.
