A kind of cultivating method of trellis pear tree trunk and auxiliary branches

Abstract

The invention belongs to the fields of fruit tree cultivation and fruit tree ecology, and in particular relates to a method for cultivating auxiliary branches of a novel trellis pear tree trunk, comprising the following steps: 1) after the spring is fixed, select two vigorously growing branch tips, and the rest The branches are topped. After the heavy topping, the shoots of the buds below the topping branches are topped again for 1-2 times; 2) the branches that are sent out from the branches after the first heavy topping are topped again, for 2 consecutive times; 3) after 2 times of heavy topping The topping branches are treated with ring branches; 4) In winter, the auxiliary branches other than the main branches are thinned out. The present invention adopts heavy topping+circling treatment on the new shoots on the main trunk, which reduces the nutrient competition of other shoots to the main branch. Compared with the simple coiling treatment, the number of leaves increases by 38.8%, and the length of the main branch increases by 56.4cm. The branch diameter increased by 4.6mm, which significantly promoted the growth of the main branch, enhanced the tree vigor, and accelerated the pruning process. The invention promotes the large-area popularization of the tree shape of the high trunk scaffolding, and promotes the development of the mechanization and standardization of the pear orchard.

Description

technical field [0001] The invention belongs to the fields of fruit tree cultivation and fruit tree ecology, and relates to a method for cultivating the trunk and auxiliary branches of a novel scaffold pear tree. Background technique [0002] Pear trellis cultivation is an important way of high-quality pear fruit cultivation. With the aging of the rural population in my country and the increasing shortage of labor force, the trellis cultivation mode is more and more favored by pear fruit production enterprises and cooperatives, and it has shown a rapid development trend in recent years. The general theory of pear tree cultivation believes that if the fixed trunk is short (within 60cm), the tree will be stable and the crown will expand rapidly; with the increase of the fixed trunk height, the tree vigor will weaken; if the fixed trunk is too high (more than 1 meter), the tree will be weak, Therefore, high-trunk tree shapes are rarely used in production. The reason is that i...

Problems solved by technology

This patented technology increases the height of the fixed trunk of the scaffolding pear tree to 1.3-1.4 meters. The auxiliary branches are treated with ring branches to promote the thickening of the tree body, so that the tree shape of the high-trunk scaffolding has been popularized and applied. The number of auxiliary branches is large, while increasing the leaf area of ​​the tree and promoting the thickening of the main trunk, it also forms an obvious nutrient competition with the growth of the main branch, resulting in weak growth of the main branch.
