1. The best time for planting is to follow the planting, to get up too early, and the saplings lose water and water for a long time, which is detrimental to the survival and growth of afforestation.
2. The nursery was watered in winter and spring in arid areas. The soil in the nursery was hard to lift and the seedlings were difficult to lift. The nursery had to be irrigated 5-6 days before the start of the seedlings. This would not only facilitate the raising of seedlings, but also ensured that the roots of the seedlings were intact and the nursery stock could be used. Sufficient water absorption to increase the water content of seedlings and enhance the ability of seedlings to resist drought.
3. The seedling depth should be based on the root distribution rules of each tree species, and should not be shallow. It is too shallow, the roots are too many, the roots of the saplings coming out are few, and the survival rate is low or the growth is weak; for the long main root or lateral roots, it may be cut off due to the inconvenience, and avoid cutting the seedlings by hand to avoid tearing the roots or Root bark collapsed, otherwise it will affect survival.
4. To bring soil ball evergreen seedlings and big trees to dig, take soil ball and wrap it with straw rope. This will prevent the root system from being exposed to the air, causing it to lose water. At the same time, after the planting, the roots and soils are closely connected, and the roots can resume their absorption function quickly, which can improve the survival rate of evergreen seedlings and large tree transplants.
5. Seen from the day the seedlings do not raise the seedlings on a windy day, the windy seedlings are more likely to lose water, affecting survival. In the rainy days, evergreen seedlings should not be allowed to grow. Because the branches and leaves are easy to get mud, affecting the afforestation effect and photosynthesis.
