What is the best time to fertilize jujube trees? When are jujube trees generally fertilized? When should jujube trees be fertilized and what kind of fertilizer should be used in each period?

1. Jujube base fertilizer

　　The base fertilizer of jujube trees should be mainly organic fertilizer, and some quick-acting fertilizer should be applied appropriately. Combined application of quick-acting nitrogen fertilizer or nitrogen, phosphorus, potassium compound fertilizer can promote the absorption of nutrient elements by the root system and increase the accumulation of stored nutrients by the tree.

2, Top dressing of jujube trees during flowering

　　 Jujube trees can be supplemented with nutrients in time during the flowering period, which can not only increase the fruit setting rate, but also benefit the growth and development of the fruit. For top dressing during the flowering period, the method of spraying urea on the leaves is often used, so that it is absorbed quickly and is beneficial to timely supplement of nutrients.

3. Jujube Puffing Fertilizer

　　 This top dressing is appropriate in mid-July. In addition to topdressing nitrogen fertilizer, phosphorus and potassium fertilizers are combined to meet the demand for phosphorus and potassium for jujube fruit development and improve fruit quality.

4, The late topdressing of jujube

　　 Late topdressing can be sprayed with nitrogen fertilizer and combined with a certain amount of phosphorus and potassium fertilizer. The jujube trees sprayed with fertilizer in the later stage of the experiment can delay the senescence process of the leaves, improve the photosynthetic efficiency of the leaves, and create conditions for the accumulation of nutrients in the later stage.
