1, temperature management method In the pre-seedling stage of cherry tomatoes, temperature control is very important. It should be adjusted to 28 degrees, and the temperature difference between day and night should be maintained at 10 degrees. The temperature at night shall not be lower than 13 degrees. Subsequently, the temperature was kept at about 22 degrees in the time range from complete emergence to emergence separation of cherry tomatoes. Then the temperature will rise to 28 degrees after the seedlings are divided. At all seedling stages, the temperature should be adjusted according to the growth of seedlings. Controlling the temperature is very important for the growth of cherry tomatoes, so everyone must pay more attention.

2. Wind resistance and disease prevention Before the cherry tomatoes germinate completely, they should be given a moderate high temperature environment to promote the cherry tomatoes to germinate as soon as possible. After the tender leaves of seedlings are developed, the temperature should be moderately lowered, mainly by watering flowers. During the day, the temperature is above 20 degrees, and at night, it is about 1 1 degree. After the seedling leaves, reduce the ventilation, and then pay attention to increase the light time to promote the growth of young leaves. After the cherry tomato has two leaves and my heart leaves have all grown, I should spray mancozeb or moderate mancozeb once to prevent diseases.

3. Effective fertilization In the pre-seedling stage of cherry tomatoes, the market demand for nutrients is relatively large. Therefore, in the case of pre-seedling, everyone needs to pay attention to fertilization. According to the growth status of cherry tomato seedlings, fertilization should be effective, and sufficient nutrients should be given to the seedlings to promote the growth of the seedlings. When cherry tomato seedlings grow to about 3 leaves, topdressing should be done as much as possible to improve seedling fertilizer, and topdressing should be done for about 3 times. Fertilizer should be mainly compound fertilizer such as light fertilizer, not just fertilizer, but also combined with irrigation to prevent fertilizer from burning seedlings due to excessive calorific value.

If the cherry tomatoes are transplanted to the open field, they will suffer from freezing injury. Therefore, attention should be paid to the hardening of seedlings before transplanting. In the case of hardening seedlings, it is necessary to ensure that the seedlings can withstand the low temperature environment of MINUS two to one degree. When hardening seedlings, slowly remove the straw cover and gradually remove the covering layer at night. Let the seedlings accept the bottom temperature exercise of open field cultivation, and pay attention to reducing the watering amount moderately in the middle and late stage of seedling exercise. Because of the slight drought, the natural environment can play the role of hardening seedlings.
