1. Drying: Seedlings shall be dried in a timely manner after colonization, that is, the excess part of the upper part shall be cut off, and the height shall be 60-80 cm. After drying, smear with a paint to prevent moisture loss in the young tree. Drying early can reduce the water consumption of the seedlings and help the seedlings survive and grow. Pay attention to the buds at the cut-outs should leave strong buds, and leave about 1 cm of piles on the buds to drain and cut off the top buds with water loss.
2. Stubbles and plastic surgery: After filling, most of the sprouts on the seedlings can germinate. However, only three to four buds are grown under long-term conditions, but the remaining growth is small. It is a few Wang branches, therefore, the buds on the lower part of the seedlings and the sprouts on the rootstock should be wiped out early to facilitate the growth of the seedlings.
3. Watering and Topdressing: About a week after the seedlings are planted, the mound around the seedlings should be plowed and the water should be poured once. The amount of water should not be too much. After watering, stack the mounds to keep the roots wet. Watering this way 1 or 2 times will ensure survival. This is a key measure to ensure the survival rate in arid regions. After the seedlings have survived, the previous fertilizer and water management should be strengthened. In the early stage, quick-acting nitrogen fertilizers were dominant, and urea was recovered once in mid-June and early July. The amount of each plant was 0.10 kg. By the end of July, each plant was topped with 0.15 kg of potassium dihydrogen phosphate. At the same time, from August to September, a 0.2% potassium dihydrogen phosphate solution was sprayed once every 10 to 15 days.
4. Control of pests: After planting, in order to prevent pests from harming new shoots, the branches are bagged before budding to protect the buds from harm. After the new shoots are spread, they are easily damaged by insect pests. The common pests are scarabs, aphids, leaf curlers, and caterpillars from the sky. Early detection and prevention must be done.
5. Prevention of animal pests: In areas where rabbits and rats are infested, tie a barbed branch or a protective agent with a foul odor on the seedlings to prevent damage to the animals. At the end of autumn, the whitening agent mixed with lime sulfur should be painted on the trunk to effectively prevent the damage of the rabbit.
