The fertilization of jujube can be divided into base fertilizer and topdressing fertilizer: 1. Base fertilizer. The purpose of the fruit harvest is to increase the storage nutrition of the tree in order to meet the needs of budding, flower bud differentiation, flowering and fruit setting in the following year. On the basis of sufficient organic fertilizer, each tree is generally applied 0.8 kg of Tianji brand nitrophosphate fertilizer. 2. Topdressing. Topdressing before sprouting: generally carried out in the first ten days of April, each plant is applied 1.5 kg of Tianji brand phosphate and potassium nitrate. Topdressing in fruit setting period: generally carried out in the first ten days of June, each plant applied 0.8 kg of Tianji brand phosphate and potassium nitrate. Fruit expansion period topdressing: generally carried out in mid-early August, each plant applied 1.2 kg of Tianji brand nitrophosphate fertilizer. In addition, 0.3% potassium dihydrogen phosphate can be sprayed 2 times 3 times from mid-late April to mid-August.
