Appropriate temperature during the flowering period of tomato is 24-26°C and nighttime is 12-14°C. The flowering period of tomato was sensitive to temperature, especially from 5 days before flowering to 3 days after flowering. Less than 12°C and higher than 30°C were not conducive to flowering, pollination and fertilization. Second, the initial flowering pruning The first big flower on the first spike of the tomato will affect the other flowers and it must be destroyed in time. Before the first fruit is sitting, it is not advisable to cross it too early. If it is too early, it will reduce the early growth of the plant and affect rooting. Generally when the cocoon grows to about 10-12 cm, knock it out. After the first fruit is seated, the upper part of the tomato should be promptly knocked out. Pay attention to reducing the wound as much as possible when crossing. Work with pruning and forklifts. Third, take care of matters needing attention 1. Regardless of the type of simmering agent used, different concentrations should be used according to different temperatures. In strict accordance with the spray pharmaceutical instructions; 2, to avoid repeated flowering; 3. It is best to spend the morning on the day of flowering. 4. In the early spring, the temperature of the greenhouse is low, and the humidity is more conducive to the occurrence of gray mold. The pathogens are easy to invade through the wound or the weak residual flowers. The flowering period is the peak of pathogen infection. Therefore, wolfberry flowers should be combined with control of gray mold, can be added in the preparation of nectar liquid 50% fluocin suspension or 40% Shijiale suspension agent, add 1ml per jin of water. IV. Pest control in the early flowering period The main insect pests in this period are whitefly and leafminer. The control of whitefly using imidacloprid plus buprofezin to prevent and control leafminers can be sprayed with agents such as AA salts and spot latrines. After the tomato entered the early flowering period, it also reached a high incidence of disease. Disease prevention and control should follow the principle of "prevention first, prevention and control combined", do a good job in cultivation and management, spray the protective fungicide regularly before the occurrence of the disease, and do a good job of prevention in advance. In the event of disease, spray the medicine in a targeted manner at the early stage of the disease.
