2. Transplanting management methods The planting of jujube trees must be particularly cautious and meticulous, because the survival rate of jujube trees planted in that way will be high. Therefore, in the case of transplantation, we should pay attention to the continuous initial foundation soil of Ziziphus jujuba, and the holes dug during planting should be very effective, at least the roots of Ziziphus jujuba can naturally expand and contract. At this time, we should pay attention to cover the main stem with fine soil first, then tamp it gently, and then fill the cave with other soil.
3. Relative density management method Green jujube trees grow well and can be stored for a long time. Therefore, in the case of initial planting, everyone should pay attention to the relative density of planting to ensure the permeability between gardens. Usually, we plant it according to the spacing of cm per row and 5 meters per tree. The relative density of planting is very high, which not only consumes the cost, but also will continue to improve the task for future cultivation techniques.
4. Liquid fertilizer management methods Green jujube trees grow faster, which means they need a lot of nutrients. Therefore, in the case of fertilization, people must apply fertilizer in batches and apply fertilizer scientifically and reasonably according to different stages of green jujube trees. For example, during the pruning period of fruit trees, everyone mainly promotes the growth of branches with base fertilizer as the leading factor.
Potassium fertilizer and phosphorus-potassium fertilizer are the main factors in the fruit-bearing period of jujube trees, supplemented by base fertilizer and boron fertilizer. At the same time, we should also pay attention to the water management methods in the field. During the growth period of its branches, there must be a lot of water, but the field must be kept dry before flowering and fruiting, and the water can be gradually watered until the thumb is big.
5. Pruning and shaping Because the branches of Zizyphus jujuba grow very fast, everyone must prune the branches of Zizyphus jujuba regularly and maintain a stable tree shape, which is not only beneficial to cultivation techniques, but also can improve the permeability of the field and reduce the harm of diseases, thus ensuring the increase of Zizyphus jujuba production.
6. Pollination management method: Pollination trees should be selected in the process of planting green jujube trees. Although some trees are not intercropped and pollinated, in order to improve the yield, sales and quality of Zizyphus jujuba, we can make scientific and reasonable layout and effectively plant pollinated trees in a herringbone way, so that the probability of successful pollination is higher. Secondly, in the next period of time, we must make scientific and reasonable thinning of flowers and fruits, so as to ensure the quality of green dates and not appear in the middle and late stages.
7. Growth characteristics of jujube trees: Jujube trees mainly show the growth habit of continuous growth all year round. As long as the environmental temperature is suitable, the terminal bud will grow forward and sprout branches with it. Branches grow into costal cartilage every three nodes. On the branch, there are 1 subordinate branches every three nodes. Finally, the main branch is generated at the branch level. The primary branches (main branches), secondary branches and tertiary branches (fruit branches) can grow to 2 meters, and the average number of secondary branches is 16.
