Pinus sylvestris seedlings have relatively high technical requirements, and nursery selection and seedling management are not only strict, but also wintering management is more important. If not managed properly, there will be a large area of ​​death in the second spring. Now introduce wintering management of seedlings. Pinus sylvestris seedlings have relatively high water requirements. To prevent the seedlings from losing water during soil freezing (especially to prevent the spring part of the seedlings from sprouting, and the soil is not thawed and the seedling roots cannot absorb water and cause physiological drought), the cover must be overwintering. Coverage time should not be too early, otherwise the seedlings are perishable. Soil is generally covered before the soil is released in the fall, that is, in late October and early November. The method is to irrigate the seedbed once every 5 to 6 days before the cold, then push the seedlings in one direction and break the trails to cover the seedbed. The thickness of the cover is slightly covered by the seedlings. In late spring and early mid-April, the cold soil can be removed when the soil is frozen. The withdrawal of the soil will be carried out in two stages. The first time, half of the soil will be removed and the seedlings will be slightly removed. The second time, all the soil will be removed. After the soil is removed, it should be watered in time to prevent the seedlings from being damaged by the wind.
