A method for shaping pears on a trellis in a pear orchard

Abstract

The invention discloses a method for shaping shed pears in a pear garden. The method comprises the steps of building a shed frame in the pear garden in which the shed pears are planted and is characterized in that the tops of grafted seedlings are cut, wherein branches close to the cut tops are diagonal branches, side branches are reserved on the diagonal branches at intervals, each side branch is matched with 2-3 auxiliary side branches in an alternate way, and all elongated heads on a trunk and the side branches of the diagonal branches grow upwards at the angle of 45 degrees; a vertical fixed rod is arranged at the root of each trunk of each grafted seedling, and an upper shed guide rod is away from each fixed rod by 1.5m; the first bud branches and the second bud branches on the tops are vertically upwards bond by the vertical fixed rods, and all the tips are twisted when the buds germinated at the lower parts of the diagonal branches grow to the period of half lignification; in winter, the second bud branches on the tops are pruned from the roots, and the bud branches at the first bud cuts are bond on the upper shed guide rods along the reverse direction to form a tree-shaped structure leaning to one side. The main branches, the side branches and the auxiliary side branches are reasonably configured, so that the method is less in trimming work and easy to master; the trimmed tree structure is simple, the early yield is high, and the method is easy to popularize and apply.

Description

technical field [0001] The invention belongs to the field of fruit tree cultivation, in particular to a method for shaping pears on a scaffold in a pear orchard. Background technique [0002] Modern pear scaffolding cultivation technology originated in Japan. Pear tree scaffolding cultivation can reduce the losses caused by typhoon attacks, facilitate daily management of orchards, high yield per unit area, and good quality pear fruit. The traditional pear tree cultivation method in my country is the standing tree type , In 1995, Dalian City was the first to introduce the Japanese pear trellis cultivation technology. According to incomplete statistics, there are about 100,000 hm of scaffolding pear orchards in my country 2 , mainly distributed in Shandong, Liaoning, Hebei, Zhejiang, Jiangsu, Shanghai, Fujian, Jiangxi and other eastern coastal or offshore provinces and cities, and a small amount of planting in Hubei, Henan, Anhui, Sichuan and other provinces.

Problems solved by technology

[0009] The main tree shape of the imported Japanese scaffolding in my country is mainly the split-shaped tree shape. Judging from the current production situation of the imported tree shape, the pruning of the tree shape is complicated, and the problem of branch structure confusion often occurs on the shed surface. On the one hand, because Pear tree trellis cultivation technology is still in the demonstration and promotion stage in my country. On the other hand, farmers do not know how to comprehensively use techniques such as pruning, water, and fertilizer to control tree vigor

Therefore, the growth of the main branches of the different tree shapes is different; the "identities" of the main branches, side branches, and auxiliary side branches are not clear; the extension direction of the main branches and side branches is not clear; The upper branch develops to form a "mountain" shape; and the growth potential of the main branch and sub-main branch is weak, so the tree shape shows that the tree phase is chaotic, and the effect of scaffolding cultivation cannot be achieved, resulting in weakened tree vigor, reduced yield, and reduced fruit quality.
