Inverted-umbrella-shaped cultivation technology for peach trees

Abstract

The invention discloses an inverted-umbrella-shaped cultivation technology for peach trees.The technology comprises the steps of defining the plantation density; conducting shaping and trimming in a quantitive mode, wherein the central trunk of a tree is robust, erect, free of principal branches or lateral branches, two adjusting branch sets grow out of the basal part of the central trunk, small bearing branch sets directly grow out of the remaining parts of the central truck, the small bearing branch sets are distributed at an interval of 10-15 cm and uniformly arranged upward in the helical form, the tree height is 2.5-3 m, the crown diameter is 1.5-2 m, the trunk height is 50-70 cm, the growing points of the two adjusting branch sets are vertically staggered with the spacing being 10-15 cm and are distributed at the angle of 180 degrees, the included angle between the growing points of the two adjusting branch sets and the line direction of a plantation line is 30 degrees, meanwhile the included angle between the growing points of the two adjusting branch sets and the central trunk is 40 degrees, attention is paid to control the thickness of branches on the central trunk so that the thickness cannot exceed 1 / 3 or above of the thickness of the central trunk, and thinning is conducted when necessary.By means of the inverted-umbrella-shaped cultivation technology for the peach trees, early fruiting and a high and stable yield are promoted, the full productive age of the peach trees is prolonged, the commodity rate and high quality fruit rate of fruits are raised, meanwhile, work efficiency is improved, and labor intensity is lowered.

Description

Technical field: [0001] The invention belongs to the field of fruit tree cultivation and fruit tree ecology, and specifically relates to a peach tree inverted "piece"-shaped cultivation technique. Background technique: [0002] Tree shape is the basis of peach cultivation. In the process of peach production, peach trees need to be pruned reasonably to form a high-yield structure. The traditional natural happy-shaped tree shape is gradually eliminated. The peach tree trunk-shaped cultivation technology is being promoted and applied. The peach tree grows prosperously in the warm and humid area south of the Huai River. With the top advantage, it is difficult for ordinary fruit farmers to control the tree structure. It is easy to cause the main trunk to be shaped into an umbrella shape, that is, the upper part is strong and the lower part is weak, which affects the overall light of the tree body and easily causes the lower half of the tree body to die. Therefore, after repeated tria...

Problems solved by technology

The traditional natural happy-shaped tree shape is gradually being eliminated. The trunk-shaped peach tree cultivation technology is being promoted and applied. The peach trees grow vigorously in the warm and humid area south of the Huaihe River. With the advantage of the top, it is difficult for ordinary fruit farmers to control the tree structure. It is easy to cause the trunk to become umbrella-shaped, that is, the top is strong and the bottom is weak, which affects the overall illumination of the tree and easily causes the lower half of the tree to be bare and dead
