How to maintain the grafted pine seedlings in the later stage?
1. If the seedlings grafted before the end of July want to develop into finished seedlings in the same year, the original rootstock should be folded in half (half knocked) 5- 17 days after grafting to promote the direct supply of nutrients to the seedlings. You should also untie the rope between 10 and 15. If the seedlings grafted after the beginning of August cannot become the finished seedlings of that year, there is no need to untie the rope and fold the branches.

2. No matter the finished seedlings or semi-finished seedlings grafted in the same year, the lower buds that affect the development and enrichment of grafted buds must be broken in stages in time. The smaller, the earlier, the less nutrition consumption.

3. The finished seedlings developed by grafting in that year should be cut in time. If the grafted seedlings and the surviving ones are untied before the end of July, it is necessary to leave about two inches on the grafted seedlings for the first time. When the seedling grows to about 30cm, leaving about 0.5cm on the bud for secondary anvil cutting is beneficial to healing.

4, the newly cultivated grafted seedlings should pay attention to soil sealing or support, to prevent the wind from breaking.

5, pay attention to the fertilization of seedlings, irrigation should be timely intertillage soil moisture conservation.

6. Leave enough plastic belts according to different varieties, carry out core picking on seedlings, and do a good job in seedling shaping.

7, do a good job in the prevention and control of various diseases and insect pests of newly grafted seedlings, and promote the healthy development of grafted seedlings.
