Hard branch cutting method of jujube

The robust jujube head was collected before sprouting, and the middle and lower part of the jujube was cut into cuttings with 3 to 4 nodes, the upper end was cut flat at 1 cm from the top node, and the lower end was cut obliquely at 2 to 3 cm below the basal node. The cut cuttings were first buried in clean wet sand for 30 to 40 days to soften. Before cutting, soak the cuttings with indolebutyric acid or acetic acid with a concentration of 100 to 200 mg per liter for 24 hours, then cut the cuttings obliquely in the trench and leave 1 bud above the ground. 30 plants per square meter of seedbed. Water thoroughly after sowing. When cutting in the open field, plastic film mulching can improve the higher humidity of the bed; when cutting in the open field, plastic film mulching can improve the bed and preserve soil moisture gently.
