Apple canopy closed garden pruning method

Abstract

The invention belongs to the technical field of fruit growing, and particularly relates to an apple closing garden pruning method. The apple closing garden pruning method comprises the following steps of removing heads and tails of branches and thinning out large branches after picking apples and before leaf falling in the autumn; trimming extended single shafts of principal branches in the late winter and the early spring; and trimming the branches again before blooming in the spring. By the apple closing garden pruning method, adverse effects of pruning in the winter can be avoided, different pruning measures can be taken in different periods step by step, orchard workers can learn and master the apple closing garden pruning method conveniently, and the pruning ability of the orchard workers can be improved; the pruning time is reasonable, the pruning goal and the pruning principle are clear, the branches are thinned out wisely, tree vigor recovers robustly, tree bodies have a ventilating effect, light can pass through the tree bodies, insides and outsides of the tree bodies bear apples, the quality of the appears is improved, and the yield is high and stable in successive years; and the orchard group structure is effectively adjusted and optimized, light conditions of an orchard are improved, and flower formation, quality improvement and efficiency improvement are facilitated.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and in particular relates to a pruning method for closed apple canopy orchards. Background technique [0002] Most of the red Fujis in the main apple planting areas of our province were planted in the late 1980s and early 1990s. Three types of plastic models, namely free spindle, small canopy and sparse canopy, and large canopy and sparse canopy were generally adopted. Now most of the orchards are relatively closed. serious. However, many fruit growers do not pay enough attention to this. They do not know how to prune or do not have a comprehensive grasp of pruning techniques. Which branches should be pruned? Which branches should not be pruned? When is the best time to prune fruit trees? What is the purpose of pruning is unclear, and the basic principles of fruit tree pruning have not been mastered. The orchard is closed, the main branches overlap and cross, the large branche...

AI Technical Summary

Problems solved by technology

The orchard is closed, the main branches overlap and cross, the large branches are kept too much, the fruiting branches in the inner chamber are insufficient, the fruiting parts move outward, and the quality of the fruit declines

Fruit farmers are used to pruning fruit trees intensively in winter. Too many branches are thinned at one time, and the cutting edge is easy to lose water and shrink, which is not conducive to wound healing and is prone to rot

Many fruit growers don’t care about it after one-time pruning. Some meticulous pruning work is often not done properly, which is not conducive to high and stable yields year after year.
