High-position multi-point debarking method of winter jujube tree

Abstract

The invention discloses a high-position multi-point debarking method of a winter jujube tree, which is characterized in that the 3-5 vigorous main branches or the vigorous large fruit branches and the central trunk of the winter jujube tree which grows for 3-12 years are selected and debarked at multiple points, the debarking positions are at smooth positions which are 10-30cm far away from the stem base growing point of the winter jujube tree, 1-3 main branches per tree are not debarked to foster a tree body, nourish roots and strengthen the tree, and the problem that the tree dies because the trunk is improperly debarked can be effectively prevented. The width of each debarked opening is 0.8-1.0cm and 10-15ppm gibberellin is sprayed for 1-2 times within 1-7 days after debarking. The method disclosed by the invention has the advantages that the crown is formed rapidly, the tree can step into a fruiting period very rapidly after debarking, the tree body growth well, the tree is vigorous, the disease resistance is strong, the yield is increased very rapidly, the tree can step into a full fruiting period, the average yield per mu can reach 1250kg, the production value per mu is more than 1.5 times higher than the production value per mu of the traditional method and the benefit is very remarkable. At present, the application area in our county is more than 40 thousand mu. In consideration of the remarkable effectiveness of the method, we are energetically popularizing and applying the method.

Description

technical field [0001] The invention belongs to the technical field of agricultural trees, and relates to a "high-position, multi-point" method for opening the nails of winter jujube trees. Background technique [0002] Winter jujube is a variety with excellent comprehensive quality among the fresh edible jujube varieties. The planting area has been expanding rapidly in the past ten years, but it is difficult for young winter jujube trees to bear fruit, the time for fruiting is long, and the fruit setting rate of mature winter jujube trees is low. The problem of low yield is becoming more and more prominent. According to our long-term production practice and management experience, we believe that "opening" winter jujube trees is an effective way to solve these problems. Jujube tree peeling is to peel the jujube tree in a ring. After cutting off the phloem of the trunk, the nutrients produced by the leaves are suspended, which is conducive to flowering and fruit setting, inc...

AI Technical Summary

Problems solved by technology

However, the traditional method of opening the nails of winter jujube is carried out on the trunk of winter jujube. This method can have a direct impact on the entire tree of winter jujube. For example, if the nail mouth is too heavy or too wide, it will affect the healing of the nail mouth, weaken the tree vigor, and affect fruit setting; If the nail mouth is too light and too narrow, the nail mouth will heal in advance, and the effect of balancing the tree vigor and increasing the fruit setting rate will not be achieved.
