Seedling raising of Pinus thunbergii and transplanting of transportation trees should avoid high temperature and dry weather as far as possible, and seedling raising should be arranged in the morning or after 4 pm or on cloudy days to reduce water loss of seedlings.

Key points of planting after transplanting

After the seedlings are transported to the construction site in time for planting, personnel shall be organized to plant them immediately. First, apply rooting powder to the pit, then mix the soil with 2 kilograms of compound fertilizer mainly containing phosphorus, fill it to about 70%, and then fill it to the ground level.

Watering care after planting

After the black pine is pruned or cut off, the tree will secrete an oily substance-pine oil. The bigger the tree, the more oil it secretes. Studies have shown that if too much water is encountered in the process of pine oil secretion, the operation site is difficult to heal, and it is easy to turn black and rot, especially the injured tissue at the root. Therefore, the newly transplanted seedlings of Pinus thunbergii should not be watered in a hurry. You can spray water on the leaves of trees every day and water them normally after 3-4 days.
