Base fertilizer has a very good effect on the spring germination, shoots and fruit setting of jujube trees. The application of base fertilizer on jujube trees is generally from the time after the jujube is harvested to before the budding in the spring of the following year. The effect of autumn application is the best. Because of the high temperature in autumn, fertilizers are easy to decompose, which is beneficial to the absorption of jujube trees, and is also beneficial to the healing of root wounds caused by fertilization. In addition, it can also enhance the cold resistance of the tree, which is conducive to the safe overwintering of jujube trees.

Choose good fertilizers. Fertilizers are generally based on organic fertilizers, such as barn manure, soil miscellaneous fertilizers, cake fertilizers, plant ash, etc., and appropriate quick-acting nitrogen fertilizers, phosphorus and potassium fertilizers to benefit the tree. The amount of organic fertilizer applied should account for more than 90% of the amount of fertilizer applied, and it must be decomposed before it can be applied.
Fertilizer dosage The dosage of fertilizer should be determined according to the size of the jujube tree, the nutritional status, and the number of fruits. The general plant dosage is 35-50 kg of organic fertilizer, 1-1.5 kg of superphosphate, and 0.4-0.5 kg of urea.
Fertilization methods should be different depending on the age of the tree, planting density, soil type, and the amount of fertilizer.
Annular furrow dig a ring-shaped ditch around the periphery of the canopy, the depth and width of the ditch are 30-50 cm. Mix the fertilizer with 3 times the soil and fill it into the ditch, then fill it with the subsoil. This fertilization method is suitable for jujube young trees, and the fertilization ditch moves outward year by year to induce the root system to expand outward.
The radial furrow is applied at a distance of 30 to 50 cm from the trunk of the jujube tree. 4 to 6 radial furrows are dug outwards. The furrow grows to about 0.5 meters outside the canopy. The furrow is 30-50 cm deep and 30-50 cm wide. The furrow is shallower near the trunk. , The far trunk goes deeper into the ditch. Mix the topsoil with the base fertilizer and apply it, and then fill the trench with the subsoil. This method has less root damage and a larger contact area between the roots and the fertilizer. It is suitable for mature trees.
Strip furrow can dig a short furrow around the canopy of jujube trees. The depth and width of the ditch are 30-50 cm each. Strip furrow application should be rotated on both sides of the canopy. This method saves labor and fertilizer, and is very suitable for flat-land jujube gardens, and can also be used for mountain and hilly jujube gardens.
Spread the base fertilizer evenly on the jujube garden or under the canopy of the whole garden and the tree tray, and then turn the fertilizer 20 to 30 cm deep into the soil.
After the watering and moisture preservation fertilizer is applied, it should be watered 1 to 2 times. In this way, sufficient water can be ensured, which can not only make the fertilizer quickly rot and ferment and decompose, but also prevent the jujube from drought in the autumn when the autumn is high and airy. After watering, cover with crop straws, thatch, etc. to protect the moisture.
