Method for retaining trunk and molding green date tree

Abstract

The invention discloses a method for retaining a trunk and molding a green date tree, and belongs to the technical field of fruit growing and management. The method comprises the steps of retaining the trunk and molding, wherein the step of retaining the trunk comprises the steps of: during cutting back of branches, cutting a branch, retaining 1.5 to 2.0m of the branch to serve as the trunk, cutting out the rest branches, and respectively grafting a green date bud on a cut section of each of four to six cut branches on the periphery of the trunk; and the step of molding comprises the step of respectively binding each first-level branch with the trunk on any part of the first-level branches between 0.5 to 1.5 m from the ground to form a mushroom tree structure, wherein the trunk becomes a natural and powerful support of the green date tree. Through the method, a single green date weighs 72 to 76g, which is improved by 41 to 48 percent than a contrast; the yield of a single plant is improved by 71 to 80 percent than a contrast; the sugar content is improved by 34 to 42 percent than a contrast; the tree shape of the green date tree has a reasonable structure; the illumination on flower and fruit branches is increased; and the fruit bearing rate and the yield of the green dates are greatly increased.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation and management. In particular, it relates to a shaping method for shaping a reasonable tree shape for jujube trees and improving fruit yield of jujubes. Background technique [0002] Zizyphus mauritiana Lam is a plant of the genus Zizyphus in the family Rhamnaceae, a tropical and subtropical evergreen or semi-deciduous broad-leaved shrub or small tree. Green jujube is a typical positive plant. It has high requirements for light throughout the growth period, and it does not grow well under shaded conditions. Therefore, the length of the light time has become an important indicator of whether the jujube can grow fast, knot early, and have a high yield. The jujube tree is grafted in the same year and blooms and bears fruit in the same year. In the prior art, after the fruit of the jujube tree is harvested every year, the branches are retracted and renewed, and new shoots are grafted,...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to overcome the unreasonable shape of the green jujube tree in the prior art by using bamboo poles or wooden sticks to support the branches, and the lack of light on the flower and fruit branches affects the fruit setting rate and output of the green jujube and the high cost input. Technical defect, provide a kind of method of intercepting trunk shaping of jujube tree
