2. When is the cherry tree transplanted and when is the best cherry tree planted (the planting time and method of cherry tree)
1, in time, it is easy to survive when transplanted in early March or early June of 10.
2. When transplanting, please dig as much space as possible to loosen the soil, apply decomposed organic fertilizer, and pay attention to filling and compaction.
3. Pour 30-40 kilograms of roots on each tree, and you like to dilute it with mycophenolate mofetil 8000 times. Improve the survival rate. The best season for transplanting cherry trees is to bring as many roots as possible, especially big roots, before sprouting in spring. Then cut off the upper branches and cut off one third of the total branches. The soil is better, no problem and no big problem. The depth of planting direction is basically the same as before. Practical after planting, watering. If it is transplanted after germination, soil balls must be brought, and the cultivation method is the same as before germination.
Third, cherry trees will take several years to bear fruit. Generally, it takes three years from cultivation to first fruiting. If grafting is adopted, the cycle will be greatly shortened, and the specific choice should be based on rootstocks.
Four points for attention in cherry cultivation 1. Try planting first, then develop.
Big cherry likes warmth, is not cold-resistant, drought-resistant, moisture-resistant and afraid of strong winds, and is suitable for cultivation in areas with annual average temperature 10℃~ 15℃. Practice has proved that when the annual average temperature exceeds 15℃, cherry blossoms bloom more and bear less fruits. The introduction and development of big cherry only depends on the local annual average temperature, precipitation, sunshine, frost-free period and other factors, and it is also necessary to carefully analyze the local microclimate characteristics, try planting first, and then develop.
2. Develop hard meat storage and transportation varieties.
At present, there are only a dozen excellent cherry varieties that have been verified by planting, and each variety has certain shortcomings. Like the red light cultivated in China, the fruit is big, the color is bright, the juice is sweet, and the yield is stable. However, because it enters the full fruit stage late, the skin is thin and the flesh is soft, which is suitable for small-area cultivation. In the future, we should choose varieties with beautiful appearance, hard pulp, good quality, light crack, storage and transportation resistance, fresh food and suitable processing.
3. Focus on preventing root cancer and viral diseases.
Selecting excellent rootstocks suitable for local cultivation is the key to the success of cherry cultivation. The most important thing is to see if the rootstock is resistant to root cancer and has virus disease. In the old cherry producing areas, it is not allowed to use continuous cropping land to develop cherries, nor to use continuous cropping land to cultivate cherry seedlings. In the newly developed cherry producing areas, root cancer and virus diseases must be strictly controlled on the premise of determining improved varieties and excellent rootstocks.
4. Both pollination and fruit thinning are needed.
Most cherry varieties are not self-pollinated or have low seed setting rate, so cross pollination is needed. Cherry orchard, with low yield and few suitable fruits for many years, is not affected by freezing injury, mainly due to unreasonable allocation of pollination trees, poor flowering and poor pollination. Pioneer and Rubins are ideal pollination varieties. It is also necessary to remove the weak fruit branches, small flowers, small fruits and deformed fruits with incorrect shape and position in time, and it is best to leave 2 ~ 3 on each strong fruit branch.
