Precautions when scarring or girdling jujube trees

    Scarring and girdling can increase the fruit-setting rate of jujube trees and reduce fruit drop, but they also have the side effect of weakening tree vigor. There are mainly three points to note during operation: (1) Operate carefully, and determine the number and width of cuts and girdles according to tree age, tree vigor and environmental conditions. For jujube trees that are too weak in vigor and poor in fruiting capacity, scarring and girdling should not be carried out; instead, 2 to 3 years should first be spent rejuvenating and nurturing the trees, and only after the tree vigor has recovered should the operation be carried out; (2) Strengthen fertilizer and water management. In plots with sufficient fertilizer and water, even with scarring year after year, girdling can still maintain high yields year after year without any visible weakening of tree vigor, but when fertilizer and water are insufficient, cuts and girdles will seriously affect tree vigor; (3) Protect the wounds and promote healing.
