Now we will introduce some methods to solve the problem of winter jujube seedlings and jujube: the organic fertilizer is used in the roots to increase the organic matter content of the soil and change the soil nutrient structure. The specific products are not many, and can be selected according to the specific conditions. Often said that the orchard is covered with grass. The grass is increased in soil temperature and humidity. The jujube seedlings are beneficial to the reproduction of microorganisms in the soil and are beneficial to the activation of calcium in the soil. Autumn can reduce the temperature difference of the soil to facilitate the growth of the root system. Covering the grass keeps the soil moisture constant. Deep fertilization: change the existing fertilization method, and use the ditch application or acupoint application to guide the jujube root system to grow deep. Calcium supplementation with foliar fertilizer: Spray with the 'Fubairen' plant synergistic calcium 500-fold dilution twice before flowering, at intervals of more than 10 days. The winter jujube seedlings are sprayed 2 times before harvesting, which is rich in nutrients and improves the drought resistance, cold resistance and stress resistance of jujube trees, which can effectively control the cracking fruit. It also plays a significant role in increasing yield and improving fruit quality. Therefore, in this period, the plant is mainly based on increase. When the trunk is formed, the high growth is slow, the growth of the side branches is strengthened, the crown enlargement is accelerated, and the branching stages are gradually increased. Generally, the crown is formed in 12~13 years. To explain the relationship between the growth of jujube seedlings and the formation of crowns: the crowns of the first growing are small in size, the branches are simple, the branches are strong, and the ability to shoot is strong. The direction of the branches is mostly upright or oblique, and has certain The ability to produce results. With the increase of age, the canopy of winter jujube seedlings gradually formed the result layer and the growth result layer. After entering the fruiting period, with the increase of the result ability, the shoot growth began to decline, and the canopy growth was basically stable within a certain range.
