Question 2: What fruit trees are suitable for planting in Changsha? Changsha is warm and humid, suitable for the growth of many subtropical crops. Economic fruit trees can be planted with pear, peach, plum, chestnut, loquat, pomegranate, persimmon and jujube.
Question 3: What fruits can be grown in Hunan Province? You can grow fruits in the south, as long as you look at the terrain and the economy.
Question 4: What fruit trees are most suitable for raising chickens in Changsha, Hunan? You can raise chickens under the fruit trees. You can wait for the fruit trees to grow up before raising them, or you can enclose them before raising them. In fact, there is nothing particular about what fruit trees to plant.
Question 5: What fruit trees are suitable for planting in Hunan? Citrus or blueberries are more suitable. Buying seedlings in the city and spraying enzyme fertilizer can delay seedlings quickly without replenishing seedlings.
Question 6: What kind of trees are most suitable for planting in Changsha? The geographical location and topography of Changsha make the climate in Changsha and even the whole central Hunan more special. There are three main reasons that affect Changsha's climate: First, Changsha is located in the southeast of China and belongs to the world-famous monsoon climate zone. Affected by the monsoon, the seasonal changes are obvious, and Leng Xia is hot in winter; Second, Changsha is located in the third step of China's topography, far from the sea, with plain hills as the main terrain, and the continental climate characteristics of Leng Xia fever in winter are obvious; Thirdly, due to the ups and downs of geological times, the terrain in the middle of Hunan where Changsha is located is high in the south and low in the north, especially there are five mountains in the south, Mufu Mountain in the east, Xuefeng Mountain in the west and Dongting Lake in the north, which makes its terrain horseshoe-shaped and blocks the adjustment of westerly winds in the East and South China Seas, making the characteristics of winter cold and summer inflammation particularly remarkable. Changsha's climate features are: Leng Xia is hot in winter, with four distinct seasons; Spring and autumn are short, winter and summer are long, which fully embodies the similarities and differences of subtropical continental monsoon climate types.
Therefore, Changsha area is suitable for planting camphor trees.
Question 7: What kind of fruit trees should be planted in Changsha, Hunan? You can try to plant citrus and attach citrus planting techniques.
1. When choosing a citrus orchard, you should choose a place without obvious freezing damage, which requires deep soil layer, good drainage and ventilation, rich organic matter, convenient irrigation and convenient transportation. The hills and mountains are below 800 meters above sea level and the slope is below 25. In areas with freezing injury in winter, the southeast slope should be chosen, and gardens should not be built in low-lying areas with poor drainage and valleys where cold air is easy to stagnate. When the garden is built on gentle slopes, rivers and paddy fields below 5, attention must be paid to drainage. Natural barriers and large water bodies can be used to adjust the temperature, and gardens can be built around them. Building a garden requires a lot of surrounding environment. It is required that the citrus produced should be robust and free from pests and diseases, and the surrounding air quality, irrigation water quality and soil environmental quality should be fully understood. The standard of pollution-free food formulated by 200 1 says that the environmental quality of production process should be considered.
The planting season of 1. 1 is generally from late February to mid-March, before the spring shoots germinate. In areas without frost damage in winter, it can be planted in 10 ~ 1 1 mid-autumn; In April-May of spring and summer, after the growth of spring shoots stops, the survival rate of summer bamboo shoots is also very high. Container seedlings can be planted all year round.
1.2 The most common spacing for citrus cultivation is 4x6m, but different planting methods tend to make the citrus grow intensively in the later stage, so the spacing of 4x3m or even 4X 1.5 is often adopted. Its planting density is usually 4 10 plants per hectare, and there are 800 plants or even 1600 plants per hectare in the case of close planting. Dig the planting pit according to the specification of1×1m. Weeds, garbage fertilizer, decomposed organic fertilizer, calcium superphosphate and other base fertilizers are applied in the pit. Kechun can also be planted in autumn.
2. Management of citrus trees
2. 1 soil management soil is a loose layer on the land surface, which is composed of minerals, organic matter, water, air and organisms. It is fertile and can grow plants. Citrus grows well in light soil, but it can also grow in heavy loam if suitable rootstocks and good drainage conditions are used. The soil with pH over 8.0 is not conducive to the growth of citrus. Citrus is very sensitive to soil salt and boron (even in deep soil) and hardened soil. Citrus roots are mainly distributed in 0.90 m soil layer, which varies with irrigation conditions. The vast majority of aerobic active roots are distributed in the surface layer of soil 30 cm. In light soil, the recommended irrigation cycle is twice a week, and daily irrigation is better. Obviously, because water can easily penetrate below the active root zone in light soil, frequent and small irrigation will produce better results.
2.2 Fertilizer and water management Citrus needs irrigation in dry months, so it must be irrigated in winter when the temperature is above 13 degrees Celsius. In addition, dehydration is dangerous, which makes the fruit flow to the leaves and causes the fruit to wither. In the past, furrow irrigation or sprinkler irrigation was mainly used in the upper part of the crown, but sprinkler irrigation was at risk of salinization, and furrow irrigation would reduce soil permeability. At present, drip irrigation and micro-sprinkler irrigation are used under the canopy, which is strip irrigation and part of the soil surface remains dry. Orchards that have not fully applied phosphorus and potassium fertilizer before planting should increase the application amount of phosphorus and potassium fertilizer year by year; 1 After young trees are planted, new roots begin to move, and thin manure can be applied. The amount of fertilizer should be less than more, light, not thick, especially chemical fertilizer, and more attention should be paid not to hurt the roots. Quick-acting fertilizer should be applied 1 ~ 2 times before each new shoot sprouting and during the growth period, and new shoots germinate 3 ~ 4 times in 1 year, that is, spring shoot fertilizer should be applied from the end of February to the beginning of March, summer shoot fertilizer should be applied in the middle and late May, autumn shoot fertilizer should be applied in the middle and early July, and winter fertilizer should be applied in1/June. In areas prone to freezing injury, fertilization should be stopped from August to 65438+10 to prevent late autumn shoots and winter shoots from sprouting and avoid freezing injury caused by nutrient consumption. In the second year after planting, the amount of fertilizer should be gradually increased, combined with soil improvement, organic fertilizer should be applied, the amount of phosphorus and potassium fertilizer should be increased, and appropriate amount of lime should be added to acidic soil to cultivate dense root groups and strong autumn shoots, laying the foundation for the third year. For 2-3-year-old trees, topdressing should be applied continuously in each new shoot growth period, about half a month before the emergence of bamboo shoots, and topdressing 1 time for those with less bamboo shoots. After self-cutting or coring, topdressing 1 times of strong shoot fertilizer, and topdressing twice after autumn shoots turn green.
Pay attention to the difference between weak trees and strong trees when fertilizing. In order to ensure the normal growth of weak trees for three times and increase the number of new shoots, summer shoots can be popularized in the first year after planting. When the summer shoots grow to 7-8 leaves, they can be picked and fertilized, so that the fertilized summer shoots are full and strong. Fertilization can promote the early autumn shoots to be strong and can play the role of nourishing the strong shoots with small fertilizer. In the second year after planting, the summer shoots of weak branches should not be cut short because of poor nutritional conditions. & gt
Question 8: Is Changsha, Hunan suitable for planting fig trees? There are many propagation methods of fig, generally cutting propagation is adopted. Cutting can be done in most months of the year, and the survival rate is very high. Cutting seedlings can bear fruit when planted in the early spring of the following year, and some even can bear fruit in the same year, and soon enter the peak of bearing fruit, and the yield per mu is as high as 1000 kg or more.
First, the technical points of cutting seedling.
1. Select soil without saline and alkali. Although it is resistant to salt and alkali, it contains a little more salt and alkali, which is easy to die when cutting. It is best to use sandy soil with fertile soil and soil with high organic matter content.
2. Cutting should be carried out when the juice stops flowing after defoliation in autumn, such as cutting before germination in spring. Take the sprouting branches on the ground of the mother tree or the lower part of the trunk of the mother tree as cuttings. In order to ensure the storage quality, the cuttings should be soaked in clear water for about 3 days before storage. After fishing, cuttings should be layered with sand, watered with proper amount of water to keep the soil moist.
3. Cutting method: cut with cuttings with appropriate thickness, cut flat, without splitting, and the length is about 20 cm. According to local conditions, the ground should be subdivided and fertilized to make beds. Generally, the bed width is 50 cm, the bed height is about 33 cm, or the ridge spacing is about 35 cm. Ridging, cutting and watering, cutting depth 17- 18 cm. The cutting time should be about 3 days before the local healing and rooting period. At this time, cutting can reduce the influence of adverse external climate, and its healing and growth speed is fast.
4. Management after cutting Although fig cuttings are easy to heal and take root, we should also pay attention to the management after cutting. The main points of management are as follows: ① the healing tissue needs high temperature, and the ground temperature should be raised in time; At the same time, strengthen water supply. In the later stage of healing and rooting, the cuttings will grow many hairy roots. At this time, the temperature is gradually rising, and attention should be paid to increasing soil moisture. (2) Never pour mud after healing and rooting to avoid burning leaves, especially low-bed cuttings; (3) insist on water wet soil, water less or no water when the soil is wet. If the soil is dry, it is advisable to water it more and keep it moist. (4) Ficus carica seedlings are not cold-resistant, so it is necessary to do a good job of cold prevention (freezing) and heat preservation before freezing or cold in spring. The simple method is to bury the soil or cover the grass curtain, leaves, straw and other mulch; ⑤ When the seedlings enter the vegetative growth period, the compound fertilizer with nitrogen fertilizer as the main component should be lightly applied once a month. The amount of fertilization increases gradually with the growth of seedlings, and with the deepening of seedling roots, the effect of deep ditch application is better, but attention should be paid to avoid root damage when fertilizing.
Second, the cultivation points of fig
1. Planting can be done in potted plants or in barren slopes, fields and courtyards. When farming in barren hillsides, fields, courtyards, etc. Generally, the planting density should be increased appropriately, i.e. 1 m× 2 m, and the depth of a single planting pit is 50-70 cm. With a diameter of 40-60 cm, mixed fertilizers containing phosphorus and potassium (such as human and animal manure, green manure, cake fertilizer and chemical compound fertilizer) are used as base fertilizers, and the suitable planting time should be around Qingming Festival in North China, around Grain Rain in Northeast China and after defoliation in South China. If potted, it can be transplanted and planted at any time in the middle of the year, but it should avoid the flowering and fruiting period.
2. The shaping and pruning of figs are relatively simple, and the technical requirements for pruning and pruning are not high. Generally, the pruning method of natural joy and multiple main branches is adopted, but the whole plant should be kept at 3? A main branch, leaving no side branches, the main branch group is directly planted on the main branch. In the young tree period, we should focus on cultivating the main branches, pay attention to improving the angle of the main branches, promote multiple branches, and achieve the goal of rapid crown expansion. After entering the first fruit stage, special attention should be paid to cultivating more branches to promote the formation of a certain yield. Pay attention to cultivating backbone branches, renewing large and medium branches, and cutting and shrinking weak branches during the full fruit period. For trees with aging or serious diseases and insect pests, the main branches and branches can be re-cultivated by using budding branches or hidden buds on the base or branches. Figs began to ripen in mid-July, and gradually reached165438+1October. The picking of figs should generally be carried out in sunny morning or evening. When there is a small hole at the top of the ripe fruit and the peel appears the color of the inherent variety (red and yellow varieties), pick it. Over-ripe fruits are not resistant to storage and transportation after harvesting.
3. Carry out fertilizer and water management during the growth period of young fig trees. If the base fertilizer is insufficient, it should be topdressing. The method is to apply about 5 kg of decomposed miscellaneous fertilizer to the plant at a distance of about 40 cm from the main root; Potting should be applied at least 1 kg. Mature trees should be applied with decomposed agricultural fertilizer of about 15 kg, potted plants with about 2 kg, basal fertilizer before and after defoliation, and topdressing at the stage of vigorous new shoots and rapid fruit expansion is better. Fig is a fruit tree with high fertilizer tolerance, but more phosphorus and potassium fertilizer should be applied. Generally, the ratio of nitrogen to potassium is 0.5: 1: 1. Because it is drought-resistant and waterlogging-resistant, new buds grow ... >>
Question 9: What kind of saplings can be planted in Changsha, Hunan? There are many saplings that can be planted, and there are many varieties to choose from.
It depends on how you position yourself and adapt to local conditions. According to your land location and environment, your management and maintenance conditions, whether it is a kind of green landscape seedling, fruit tree seedling or bonsai material, need professional reference.
After more than ten years' breeding and promotion of famous varieties and precious sapling varieties, we can provide you with corresponding sapling selection.
Question 10: My family is from Changsha, Hunan. I want to build a farmhouse. There are hundreds of acres of mountains. What kind of fruit trees should I plant? There are many kinds of fruit trees, but landscape trees are the main ones. Now I'm thinking that the profit is not bad. My brother built a very ordinary farmhouse with an annual income of over 100,000 yuan. Our side is an island, located in laohekou city, Hubei Province. There is an island surrounded by water, which belongs to low-lying and humid land. We can see the groundwater when we dig 0.5 meters. There are 1600 households living in the whole island, covering an area of about 30,000 mu. There is a piece of land that is very suitable for a leisure resort, 8 kilometers away from the city. It usually takes 20 minutes to drive to the expressway. If anyone is willing to invest or cooperate, they can take a look at the fields and let the city people rent down every square meter to grow vegetables, which can turn them into farmers and transform a very beautiful landscape. Plant bamboo around, build thatched huts and let city people make tea on the farm. Play cards and eat farm food, but you must have your own characteristics. If people come, they hope to bring their friends and family back later. If they don't have this idea, they have failed. Farms can launch picnics, barbecue buffet, farm dishes, farm parties, beach open-air weddings and blind date parties. ........
