For jujube management, organic fertilizer should be the main base fertilizer, mixed with appropriate amount of chemical fertilizer. The amount of base fertilizer applied should account for more than 70% of the total amount of fertilizer applied to jujube trees. The following points should be paid attention to when establishing the variety and quantity of base fertilizer:

1. In the total amount of base fertilizer, if excessive chemical fertilizer is used as base fertilizer, it will cause local high-concentration fertilizer barriers. Therefore, when the total amount of jujube fertilization is insufficient, it is necessary to increase the amount of organic fertilizer in the base fertilizer to meet the requirements.

2. Use less nitrate and ammonium nitrogen fertilizers as base fertilizers. Nitrate nitrogen fertilizers are not easily adsorbed by the soil when applied to the soil, and are easily leached by rain or irrigation; if ammonium nitrogen fertilizers are applied too much, serious fertility obstacles will occur. The phenomenon of yellowing or shrinking of leaf color will also affect the absorption of calcium and magnesium fertilizers by crops.

3. Potassium fertilizer should not be too much in the base fertilizer. Although potassium fertilizer is not easy to be leached out by water when it is applied to the soil, excessive potassium fertilizer application will affect the absorption of calcium and magnesium and easily cause calcium and magnesium deficiency.

4. Organic fertilizers must be fully decomposed before they can be applied. Otherwise, it will burn the root system and cause the death of young trees in severe cases.
