Jujube trees need to be "four water and four fertilizers" in case of drought

Jujube trees need to be poured with four waters during the year of growth, such as drought and rain: 1. Flowering water. Watering during flowering can increase the flower buds, prolong the flowering period, and promote the elongation of the fertilized organs and the germination of pollen grains. 2. The first time to expand the fruit water. It should be combined with the first topdressing of jujube trees at the same time, and the watering time should be implemented before the physiological fruit drop. 3. The second expansion of fruit water. The jujube should be combined with the second top dressing, and the watering time should be carried out during the jujube fruit ripening period. 4. Coloring water. Not only can it reduce the phenomenon of jujube fruit in the case of high temperature wrinkled skin, but also reduce the phenomenon of rain and cracking.

At the same time, jujube trees need four fertilizers: 1. Base fertilizer. It is usually carried out after picking of jujube fruit or before germination in the coming year. 2. Foliar fertilizer. Foliar spray fertilizer is mainly based on amino acids, and has certain curative effects on anthracnose, sunburn and jujube yellow leaf disease of jujube fruit. 3. The first top dressing. The first top dressing should be in the first expansion period of jujube fruit, and the topdressing is mainly based on nitrogen fertilizer. 4. The second top dressing. The second top dressing should be in the second expansion period of jujube fruit, and the top dressing is mainly potassium.
