Chestnut tree pruning method for general cutting-back castration and yield increase

Abstract

The invention relates to a chestnut tree pruning method for general cutting-back castration and yield increase. When crown closure in a chestnut orchard comes near, after leaves fall and before the Spring Festival, thin and weak useless branches are thinned and removed by adopting a centralized pruning method, then mother branches retained for fruiting undergo cutting-back processing, the upper portions of male flower sections of annual branches are removed, the length of the retained branches is 5-10 cm, 3-4 buds at each base portion are retained, and the pruned and retained branches extend in a single-end mode; the branch retaining amount is 12-15 per square meter; tree shapes are open heart shapes. In the pruning way, males can be thinned by 60-80%, accordingly nutrition is saved, tree vigor is strengthened, and the female flower amount is increased by 8-10%. In addition, the growth of branches of branch groups on the backs of the chestnut trees can be effectively controlled, the tree shapes are not disordered and can be kept for a long time, the cella branch amount accounts for 35.8% of the total amount of branches, fruits can be borne inside and outside the chestnut trees, and yield and revenue are increased. The chestnut tree pruning method can delay the lengthening growth of chestnut trees, make tree crown compact, make main branches thick, strong and firm and make the range widened due to tree crown weight increase at growing seasons small, local crown closure is not easily formed, the upward growing state of the branches can be kept, space is saved, more fruits borne on mother branches can be accommodated, and accordingly the yield is increased.

Description

technical field [0001] The invention relates to a pruning method of chestnut trees, in particular to a pruning method for commonly shortening and emasculation of chestnut trees to increase yield. Background technique [0002] It is generally believed that chestnuts form flowers and fruits from the strong branches and buds at the top of the branches. Therefore, when pruning chestnuts for the purpose of high quality and high yield, the top flower buds will not be cut off, but the traditional centralized pruning method is adopted, that is, the thin and weak branches in the middle and lower parts are removed. Keep the strong branches at the top. These strong branches are mostly long branches, usually 30-50cm, and some are longer. As a result, in the actual production and cultivation, the crown of the chestnut tree expands rapidly and is difficult to control artificially, resulting in a tall tree. The branches are heavy and long, and pruning and harvesting all need people to go u...

Problems solved by technology

[0005] The present invention aims to solve the problem of high-yield chestnut trees mainly planted in high-yield areas, which are closed and low-yield due to too large canopy, and provides a method for pruning and pruning Chinese chestnut trees generally to increase yield and yield, so as to achieve the purpose of premature yield, early abundance, and stable increase in yield
