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 Key Points of Wax-Sealing Technology for Jujube Scions
I. Benefits of Wax Sealing 1. Wax-sealing the scion forms a thin wax film on the scion surface, sealing the stomata of the scion epidermis and the cuts at both ends of the scion, reducing water evaporation by more than 90% compared with ordinary scions, thus protecting the scion. 2. The grafting period is long; jujube branch grafting is generally

Key Technical Points for Soil, Fertilizer and Water Management in Jujube Orchards
After jujube trees enter the full fruit-bearing stage, doing a good job of soil, fertilizer and water management and maintaining a good tree vigor are the prerequisites for high yield and quality. The soil, fertilizer and water management of jujube trees in the full fruit-bearing stage can be summarized as two tillages, four fertilizations and three waterings. The two tillages refer to deep plowing and intertillage. Deep plowing can loosen the soil in the jujube orchard,

How to control crown gall disease of jujube trees with good results
This disease is a bacterial disease and occurs in jujube-growing areas in the north. After the roots are damaged, the aboveground growth is slow and the plants are stunted; in severe cases the leaves turn yellow and fall early, and the branches weaken or even die, but it rarely causes the whole plant to die. Besides harming jujube trees, the pathogen also attacks
