A pruning method to enhance the growth potential of the apex of the main branch of the pear tree on the trellis

Abstract

A pruning method for enhancing the growth vigor of the main branches of trellis pear trees, including "short cutting at the front" during pruning in the first year of winter; "thinning at the rear" during pruning in the first year of winter; And pull branches; the second year of winter pruning binds the fruiting branches to the flat scaffolding surface. The pruning method of the present invention to enhance the growth potential of the main branch of the pear tree on the scaffold successfully solves the problem that the extended branch of the apex is easy to become weak in the cultivation of the pear tree scaffolding, and overcomes the main branch pruning method caused by the previous scaffolding pear tree pruning method. The problem of the large difference in growth potential between the front and rear of the main branch is beneficial to the cultivation and renewal of the tree shape and fruiting branch group of the scaffolding pear tree. This pruning technology speeds up the expansion of the crown of the scaffolding pear tree and simplifies the shaping of the scaffolding pear tree. Pruning technology is a fool-like labor-saving pruning mode, which is easy to learn and will surely promote the popularization and application of the new pear tree scaffolding high-quality cultivation mode in my country.

Description

technical field [0001] The invention belongs to the fields of fruit tree cultivation and fruit tree ecology, and relates to a pruning technique for enhancing the growth potential of the apex of a scaffold pear tree. Background technique [0002] Trellis cultivation is an important way of high-quality, mechanized and standardized production of pear trees, and has broad development prospects. In recent years, the inventors have carried out research on a new type of scaffolding cultivation model of pear trees, "two-arm anterograde", which has promoted the demonstration and promotion of scaffolding pear cultivation methods in my country. Because the branches of scaffolding pear trees are bound to grow on the surface of the scaffolding, the dominance of the top is inhibited, and the extension branches at the apex of the main branch usually become weak. The management of the extension branches at the main branch of the scaffolding pear tree is a technical problem in the management...

AI Technical Summary

Problems solved by technology

[0004] In the process of pruning, when the apex becomes weak, retraction pruning is usually used to renew the main branch and extend the branch at the back strong branch, but the result of this pruning is that the crown becomes smaller, and the main branch cannot be extended in a straight line "
