Winter-date girdling yield increasing technology

Abstract

The invention discloses a winter-date girdling yield increasing technology and is characterized by the following steps: selecting the days in flowering period, in which no rain falls in girdling period or after girdling and the daily mean temperature stands around 25-26 DEG C for over continuous 3-5 days, as the girdling time; selecting the position close to the fruiting part as the girdling part and maintaining auxiliary culture branches of certain number; controlling the diameter of the girdling part at 1 / 10-1 / 8, width of scab mouths not more than 1cm; spraying 10-15ppm of gibberellin 2-3 days after girdling, spraying again every 5-7 days, using 2-3 times continuously, spraying insecticide on the scab mouths once every 4-6 days beginning from 5-7 days after girdling, and smearing the slowly healing scab mouths with high concentration 920 agricultural chemicals 20 days after girdling. The invention solves the problems that leaves fall off untimely, trees are easy to die and the yield increasing effect is unsatisfactory due to over weakened tree vigor by traditional winter-date trunk middle and lower part girdling yield increasing technology, and the invention is suitable for winter-date yield increasing management.

Description

technical field [0001] The invention relates to the field of fruit tree management, in particular to a girdling technique for increasing the yield of winter jujubes. Background technique [0002] At present, in the management of winter jujube fruit trees, the traditional yield-increasing technology of girdling the middle and lower parts of the main trunk of the fruit tree is generally used. This technology weakens the tree too much, causing the leaves to fall off prematurely. Improper peeling often leads to dead trees, and the yield-increasing effect is not good. Ideal and other issues. Contents of the invention [0003] The present invention aims to solve the problems that the current traditional technique of girdling the middle and lower part of the main trunk of winter jujube weakens the tree vigor too much and causes the leaves to fall off prematurely, and improper girdling often leads to dead trees and unsatisfactory yield increasing effects. The technique of girdlin...
