Fertilizer purchase
Generally dominated by organic fertilizers, such as manure, soil miscellaneous fertilizers, cake fertilizer, grass ash, etc., with the appropriate amount of available nitrogen, phosphorus and potassium fertilizers, in order to enhance the tree vigor. Organic manure must be applied after adequate decomposing. Do not apply raw manure directly. If the organic fertilizer is applied to the rhizosphere of the jujube tree without being rotted, the heat generated during the microbial decomposition of the soil will cause the root system to burn, resulting in degeneration of the tree, death, or induction of rot. The amount of organic fertilizer should account for more than 90% of the amount of fertilizer.

Fertilizer dosage
The application amount of autumn fertilizing material in jujube gardens should be determined according to the jujube tree size, nutritional status, and the number of fruiting. Generally, 30 to 50 kg of organic fertilizer, 1 to 1.5 kg of superphosphate, and 0.5 kg of urea are applied.

Application skills
In combination with the Zaoyuan ploughing, the whole garden may be used for spreading, radial furrows, or annular furrows. The garden will be withdrawn and the fertilizer will be withdrawn evenly in the garden. In combination with turning the soil into the soil, the depth of tillage should be 20-25 cm. However, the shallow depth of application of this method can easily cause the roots to float, and is suitable for adult orchards and densely planted orchards. Radial grooves are less likely to cause root damage and are suitable for adult fruit trees. The trunk can be centered, digging 4 to 6 along the horizontal root extension direction, and 1 to 1.5 meters from the trunk. The depth of the ditch gradually deepens from the inside to the outside, generally 30 to 50 centimeters, narrow and wide inside, covered with soil after application. According to the experiment, deep application of basal fertilizer was better than shallow application without cutting the root system of jujube. The ring groove method is mostly used for saplings, and the annular groove is located at the outer edge of the crown projection, with a groove depth of 30 to 50 cm. Every year, as the crown expands, it moves outward.

Watering protection
After jujube gardens are fertilized in the fall, water should be poured 1 or 2 times. This method can ensure sufficient moisture, which can not only make the fertilizer rot quickly, ferment and decompose, but also make the jujube tree not dry in the autumn. After watering, when the surface is semi-dry, you should loosen the soil and cover it with crop stalks, thatch and other materials.
