(1) The sowing date should be earlier than the conventional seedling raising method. Because the survival time of grafted seedlings is 8 ~ 10 days at the initial stage of grafting, and the growth of pepper seedlings is very slow during this period, the seedling raising time is correspondingly prolonged, so the sowing time of grafted seedlings should be 8 ~ 10 days earlier than the conventional seedling raising method. (2) The sowing date of pepper and rootstock should be adjusted. The requirements of different grafting methods for sowing date of pepper and rootstock have been introduced before. The main emphasis here is that if pepper seedlings are not transplanted before grafting, only rootstock seedlings are transplanted, it is necessary to take into account that after rootstock seedlings are transplanted, because seedlings need a few days to slow down, the specific sowing date of rootstock needs to be increased by about one week. (3) The cutting position of the seedling stem should be correct. In order to prevent the leaves between grafted pepper seedlings and rootstock seedlings from colliding with each other, the joint quality of the interface should be reduced. When cutting, both pepper seedlings and rootstock seedlings should be cut on the leafless side of the seedling stem. (4) Pay attention to protect the interface of grafted seedlings to avoid splitting or breaking. The interface of grafted seedlings is generally hard and brittle and easy to break. At the same time, because the rootstock and stem segment of pepper seedlings only heal together, it is easy to crack. Therefore, in the management process of grafted seedlings, grafted seedlings should be handled with care, and grafting clips should not be taken off prematurely. (5) Ensure the growth quality of rootstock seedlings and pepper seedlings. Only when pepper seedlings and rootstock seedlings are completely * * *, can they promote each other and use each other. Once the stems of pepper seedlings come from roots, and the roots are rooted in the ground, due to the influence of kinship, the nutrients produced by pepper seedlings will be given priority to the roots, which is not conducive to the normal growth of rootstock roots and will also lead to the loss of grafting significance. On the contrary, if the rootstock grows lateral branches, the water and fertilizer absorbed by the rootstock root system will be preferentially supplied to its own lateral branches due to the influence of kinship, thus inhibiting the normal growth of pepper seedlings. Therefore, once it is found that adventitious roots grow on pepper seedlings or side branches grow on rootstock seedlings, it should be erased as soon as possible.
