Methods of releasing, interplanting and replenishing seedlings of rootstocks

After the emergence of the rootstock, cut the plastic film at the place of emergence in time and release the seedlings. When the seedling height is 4 to 5 cm, leave 2 to 3 strong seedlings at each point. If the lack of seedlings is found during the fixed seedling period, the strong seedlings that are ready to be removed can be dug out with soil, transplanted and watered immediately.
