First, under the tree management 1. Fertilize. Spring fertilization includes early application of base fertilizer and late spring application of quick-acting fertilizer. In late spring, the quick-acting fertilizer is mainly based on nitrogen fertilizer, which is carried out before and after germination from April to May. Generally, the adult tree is on the side of the tree, and 4 to 8 small pits of 30 to 40 cm deep are drilled. Each plant is applied with 0.5 to 1 kg of urea and 2 kg of superphosphate. The young trees are reduced. 2. Spring irrigation. Most of the spring in the north is dry and less rainy. Before the germination of the jujube trees, the germination water should be poured once to supplement the water needed for the germination of the jujube trees. The amount of irrigation should be based on weather, sensation, tree potential, age, etc. Spring irrigation is best combined with topdressing. Second, pest control 1. Scrape the old skin, clean up the fruit, disease and fruit, remove the diseased plant, and burn it intensively. 2. Spraying 3 to 5 waves of sulphur sulphur or 80 to 100 times of Soligobar before the germination of jujube trees to kill some wintering pests and diseases. 3. Repair the mouth. For those who have not been completely healed due to excessive armor or nailworm, they must use the spring time to repair. One is to remove the hidden biteworm in the mouth of the mouth, the second is to clean up the dead and wound tissue at the mouth of the mouth, and the third is to tightly wrap the mouth of the mouth with a plastic film.
