Last Updated: 2024/11/22, 1. Good application of basic fertilizer: this time, the fertilizer is mainly organic fertilizer, which should be applied before the defoliation of fruit trees, in order to facilitate the decomposition of organic fertilizer, and the fertilizer effect can be brought into play early next spring. The dosage depends on the variety, the size of the crown, the amount of fruit in the current year and the strength of the tree. Under the condition, 10 kilograms of charred mud ash is applied to each plant. At the same time, extra-root topdressing before defoliation can prolong the life of leaves and improve the quality of flower buds. 2. Do a good job in clearing the garden: carry out comprehensive cleaning of the garden, eliminate overwintering diseases and pests, and reduce the number of overwintering diseases and pests.

1, good base fertilizer: this fertilizer is mainly organic fertilizer, should be applied before the fruit tree leaves, the purpose is to facilitate the decomposition of organic fertilizer, next spring can play an early fertilizer effect. Dosage depends on varieties, crown size, the number of fruit and the strength of the tree, conditional application of 10~15 kg of burnt mud per plant. At the same time, before defoliation, it can prolong the life of leaves and improve the quality of flower buds.

2. Do a good job in clearing the garden: carry out comprehensive clearing of the garden, eliminate overwintering pests and diseases, and reduce the base number of overwintering pests and diseases.

(1) mainly scrape off the trunk, main branch and auxiliary main branch and large lateral branches of the thick bark, flow gum and plum branch rot disease spots, with 43% Holic 1 pack (3 ml) plus 50% carbendazim WP 25 g water 2.5 kg, or sulfur suspension agent stock solution (or water 1 times) plus "402" antibacterial agent 50~100 times, or 843 rehabilitation agent stock solution, painted on the affected part; Also available 43% Holic 1 pack plus 50% carbendazim 25g flush 15kg, spray branches.

(2) Spray 3~5 degrees of stone sulfur mixture on trees and ground, or 120~180 times of crystal sulfur.

(3) White coating: white coating agent for trunk, main branch, auxiliary main branch and large lateral branch.

3, winter pruning: time from mid-November, late to germination can be, in this period should be early. Cut off dead branches, diseased branches, thin branches, crossed branches and overlapping branches. Except for the position of excessive branches, which can be changed to fruiting branch group, they should generally be cut off from the base. At the same time, pruning is carried out according to the fruiting habits of various fruit trees. When pruning, pay attention to the following two aspects: (1) the main branch, the extension of the main branch of the cut bud must leave the outer bud, if the extension of the head position is not appropriate (angle improper, cross, too high), you can choose the appropriate branch to change the head, but the cut bud stay method is the same. (2) Pay attention to culturing fruiting branch groups and fruiting basal branches, and increase fruiting parts. For trees with large gaps in the middle and lower parts of the crown, appropriate extended branches can be selected for short truncation, leaving 3 to 5 full buds at the truncated position. At the same time, the fruit platform branches should also be retracted to 1~2 buds.

4. Deep ploughing and soil improvement: clear ditches and cultivate soil in tree trays. On this basis there are conditions as many as possible kinds of green manure. Varieties have clover, broad bean, Indian cowpea, Indonesia mung bean and so on.
