Seedbeds should be loose soil and comprehensive nutrition. During the preparation of the ground, apply 3-5 kg ​​of special nursery fertilizer for every 10 square meters to level the ground and pour it through. Spray disinfection: The day before the seedlings were divided, tomato seedlings were sprayed with 2000 times solution of Ruimiaoqing or 600 times solution of Plec for disease prevention, and the seeds were first irrigated with water to facilitate the transplanting of seedlings with roots on the next day. Seedlings should be selected after seedlings have been raised, and diseased and weak seedlings and heartless leaf seedlings should be eliminated. If the seedlings are uneven, they can be transplanted separately according to the size, which is convenient for management; the depth of the seedlings is generally 1-2 cm from the surface of the soil. If the seedlings have a long hypocotyl, the seedlings can be bent into the bed soil and tomatoes. Hypocotyls are prone to forming adventitious roots, and the curved planting of seedlings can increase the root system and reduce the height of seedlings. But when planting seedlings, the cotyledons must not be pressed.

The main points of splitting seedlings: splitting seedlings must be completed when the two leaves are focused on one heart. The tomato seedlings were sterilized and disinfected the day before the seedlings with the oxametholone brand name Rui Miaoqing 2000 times liquid or the downy mildew brand name Plec 600 times liquid. After eliminating inferior seedlings, transplant them according to the size of the seedlings. The depth of planting seedlings is appropriate when the cotyledons are 1-2 cm above the ground. If the stems of the seedlings are longer, the rods can be bent and planted in the seedling bed.
