The seedling bed should be loose in soil and comprehensive in nutrition. When preparing the land, apply 3-5 kg ​​of special seedling fertilizer every 10 square meters to level the ground and pour it thoroughly. Spray disinfection: The day before seedling division, the tomato seedlings were sprayed with 2000 times liquid Ruimiaoqing or 600 times liquid Plexick to prevent disease, and irrigated the seedbed with water first, which is beneficial for digging the roots with soil for transplanting the next day. Seedlings should be selected after emergence to eliminate diseased weak seedlings and heartless leaf seedlings. If the seedlings are uneven, they can be transplanted separately according to their size, which is convenient for management. The depth of the seedlings is generally 1-2 cm from the cotyledons exposed on the soil surface. Hypocotyl is easy to form adventitious roots, and curved planting of seedlings can increase the root system and reduce the height of seedlings. However, do not press the cotyledons when planting seedlings.

Points for seedling division: Seedling division must be completed when the two leaves are concentrated. The tomato seedlings were sterilized one day before the seedling splitting with an oxalic acid solution with a trade name of Ruimiaoqing 2000 times or 600 times with a trade name of Habracarb. After the inferior seedlings are eliminated, they are transplanted separately according to the seedling size. The depth of planting seedlings is preferably 1-2 centimeters from the cotyledons exposed to the ground. If the seedlings have longer stems, the rods can be bent and planted into the seedbed.
