After picking Ziziphus jujuba, the temperature is still high, and the root absorption function and leaf photosynthesis are still strong. Strengthening post-harvest management can lay a foundation for the high yield of jujube trees in the following year. 1. Base fertilizer. When digging deeply, 50 to 70 cm deep groove or radial sulcus, or by deep plowing in autumn, is applied into the decomposed high-quality organic fertilizer, which is usually applied in the amount of kiwifruit, 4000 to 5000 kg per mu, and applied at the same time. The long-grained long-grained fertilizer, 2 to 3 kilograms per plant. If there is no deep turning, it is necessary to deepen and deepen the hole at the same time to ripen the soil and change the physical and chemical properties of the soil. This will help maintain water and fertilizer, deepen the root distribution layer, and enhance the absorption capacity of the root system. 2. Leaf spray fertilizer. Can use 0.8% ~ 1% of urea solution or dragon light 1000 times spray. In winter, when the weather is too cold and the seeds are subjected to freezing injury in the spring, a lime sulfur mixture can be sprayed to enhance the ability to resist freezing and freezing. 3. Clear Garden scraping skin. In order to reduce overwintering pests and germs, after the jujube harvesting is completed, the diseased fruits and fallen leaves in the orchard must be cleared in time and buried or burned. When the leaves fall, the old skin on the tree must be scraped and burned outside the jujube garden to reduce overwintering pest eggs.
