Due to the late harvest of jujube fruit last autumn, tree nutrient consumption is greater. Coupled with the low temperature this spring, jujube trees sprout late. Failure to strengthen management will result in weak tree vigor and affect budding, flowering and fruit setting. Therefore, jujube trees must be strengthened in management this spring to restore tree vigor and ensure normal germination, flowering, fruiting, and maturity of jujube trees.

First, fertilization. If there is no fertilizing date garden in the autumn, it is necessary to seize the time and fertilize as soon as possible so as to provide nutrients for the jujube tree as soon as possible and promote growth. The farm organic fertilizer is applied in an amount of 2 kg of organic fertilizer per kilogram of fresh jujube, generally 4000-6000 kg per acre, and an appropriate amount of nitrogen and phosphorus fertilizer is added at the same time. Farmhouse organic fertilizer must be fully cooked and then applied. No farmyard manure can be replaced with bio-organic fertilizers (such as a special bio-organic fertilizer for plump fruit trees), and 4 to 5 pounds per plant can be used without any additional fertilizer.

Second, trim. Under the premise of moderate load, maintaining the jujube tree has certain vegetative growth, promoting root growth, and maintaining the robustness of the tree. Follow the principle of “trimming trees and shaping them with branches” to solve the main problem of ventilation and light transmission, and carry out moderate double cuts on the external jujube branches, so that the annual growth of the jujube head is maintained at about 30 cm, and attention is paid to adjusting the entire The tree's affiliation, after pruning, the total number of buds on the dates of the year should account for 1/8 to 1/6 of the whole tree, in order to ensure that the tree is strong, air and light and the appropriate amount of foliage.

Third, deepen the tree plate. Before the winter, there is no deep-turning tree tray to deepen the tree tray in the early spring. Some of the pests that overwinter in the soil can be pests or larvae such as peach, cotton bollworm, food buds, azaleas, and Zaojiao Daqiao. Frozen or eaten by birds. It is also necessary to pick up the overwintering insects as much as possible and bring them out of the park for destruction. Deeply turning the tree tray can also loosen the soil, improve the permeability, increase the temperature and protect the soil, and create better soil conditions for root growth. In addition, the planer turned off the roots of the surface layer and promoted the deep rooting of the roots, which improved the ability of the jujube tree to fight drought and resist warts. In the autumn, there is no fertilization in the jujube garden, which can be combined with deep-rooting in early spring.

Fourth, strengthen pest control. Spraying medicaments before jujube sprouts to prevent and control pests and diseases to ensure the normal germination of jujube buds. Lime spray can be used to eliminate some of the overwintering pests and germs; Spray 30% Dragonfly Fulian suspension 400 to 600 times, or 77% Donning wettable powder 300 to 400 times, or 60% Tongjia WP 300 ~400 times liquid, while adding 20% ​​faster Ling 1000 times, eradicate the tree wintering bacteria and wintering pests, the effect will be better. At the same time, we must pay attention to the pests of the jujube tree after germination and find that it is timely controlled.
