Tomato seedbed management

After sowing, the daytime temperature is controlled at 25-28 Â°C, at night it is not lower than 20 Â°C, and it can be emerged in 3 to 4 days. Before the seedlings are unearthed until the first true leaves are emitted, the temperature should be appropriately lowered to maintain a large temperature difference between day and night at 23 to 25 Â° C during the day and 13 to 15 Â° C during the night to prevent the seedlings from growing. After slowing down the seedlings, the bed temperature should be gradually reduced, and the temperature difference between day and night should be increased to facilitate the cultivation of strong seedlings. The seedlings were subjected to low temperature exercise 7 to 10 days before planting to adapt to the environment where the temperature in the plastic greenhouse was low in early spring and the temperature difference was large.
