What are the key points of summer management techniques for jujube trees?
1. Increasing fruit set rate (1) Remove root suckers. Root suckers consume a large amount of nutrients, and any root suckers found should be dug out promptly. (2) Remove buds and pinch off tips. Control the sprouting of jujube heads; all new buds with no space in the inner canopy should be removed, leaving only a few jujube hanging fruiting shoots. (3) Girdling. When 30%-40% of the flowers have opened, trunk girdling can be carried out. The width of the girdle should be 1/10 of the trunk diameter. It should be done without damaging the xylem, and the girdle cut should have no ragged edges. After girdling, apply a 200-fold solution of carbendazim and seal it with clear adhesive tape. (4) After girdling, spray the plant with 2.5-3.5 kg of ice in the morning or afternoon. Alternatively, during the flowering period of jujube trees, spray 5 ppm of 2,4-D or 10 ppm of sodium naphthaleneacetate solution.

Detailed Explanation of Summer Pruning Methods and Techniques for Jujube Trees
Traditional jujube orchard management is relatively extensive, and summer pruning is generally not carried out, resulting in disordered tree shape and small angles of scaffold branches. Although the tree is tall, ventilation and light penetration are poor, and yield is low. Summer pruning of jujube trees not only facilitates ventilation and light penetration, but also regulates tree nutrition and increases fruit set
