The Role of Girdling on Jujube Trees and a Detailed Guide to the Method

Girdling of jujube trees means ring barking: cutting through the phloem to sever the pathway by which organic nutrients are transported downward from the tree, so that the organic nutrients temporarily accumulate in the upper part of the tree to meet the needs of fruit set. After fruit set, the girdling wound heals, the pathway for downward transport of organic nutrients in the tree is reconnected, and the nutrient needs of the set fruit are met.
