2. Persimmon tree: Persimmon trees, like black dates, belong to the genus Persimmon, so besides black dates, persimmons can also be grafted. In addition, it should be noted that no matter what tree is grafted, the scion must be fresh, otherwise the grafting will fail.
Grafting method: after cleaning the anvil stake, remove the burr on the cutting surface and clean it, which is more conducive to healing. The roots split from the middle, about four centimeters deep, not too deep. Then cut the scion into an oblique angle with a knife, about 45 degrees, preferably with an arc.

Pruning method
There are five kinds in common use: thinning, retracting, cutting short, coring and carving.
1. Thinning: a pruning method to remove dead branches, useless long branches, drooping branches and branches with too dense base on the crown. Thinning branches can make the nutrients of trees concentrated, the density moderate, the ventilation transparent, and the branch potential balanced.
2. Retraction: Shrink and cut the branches that have been extended for many years and bear fruit. It can improve the angle of branches and increase the growth potential, which is beneficial to the rejuvenation of branches and the regeneration of old trees.
3. Short cutting: Shortening the longer branches can increase the nutrients in the lower part, stimulate the germination of the main buds, promote them to grow new branches, and ensure that the trees are strong and bear normal fruits.
4. Picking: During the growing season, the terminal buds of new jujube will be removed, and the jujube heads will grow longer to improve the fruit setting rate.
5. Scratch: Scratch at 1 cm above the main bud to promote the germination of new branches, which is generally useless. In order to save trouble, we mainly take shortcuts.
