Detailed Explanation of Methods for Releasing, Thinning, and Replanting Rootstock Seedlings

After the rootstock seedlings emerge, promptly cut open the plastic film at the emergence points to release the seedlings. When the seedlings reach 4 to 5 cm in height, keep 2 to 3 strong seedlings per spot. If missing seedlings are found during the final thinning period, dig out the strong seedlings intended for thinning together with the soil, transplant them to fill the gaps, and water immediately.
