How to manage tomatoes in summer and autumn? Please explain the methods.
For summer and autumn tomatoes, you can refer to the following management methods:
1. Seedbed management: Use arched greenhouse seedling raising and cover with shade netting. After sowing and pricking out, spread a layer of Wudai mixture or chlorothalonil or carbendazim medicinal soil to prevent damping-off. After the pricked-out seedlings have taken root, spray 80-100 g of 50 micrograms/ml paclobutrazol solution per sq m of seedbed to prevent seedling spindling. After emergence, keep the temperature inside the greenhouse at around 20°C during the day and around 10°C at night. The shade netting should be covered during the day according to weather conditions and removed promptly in the morning and evening. Gradually remove the shade netting one week before transplanting to strengthen hardening off.
2. Timely transplanting: Before transplanting, deep plow the soil, apply sufficient base fertilizer, and form saddle-shaped high ridges with wide and narrow rows of 50 cm and 70 cm. Transplant when the seedlings are about 40 days old, planting about 4500 plants per mu, water thoroughly after transplanting, and cover with plastic film after planting.
3. Field management: Before fruit set, keep the temperature inside the greenhouse at 25-30°C during the day and 14-18°C at night, and do not water or water sparingly. After fruit set, keep the daytime temperature at 20-28°C and the nighttime temperature at around 15°C. Stake and prune in time, and select and retain 3 fruit trusses. Keep 3-4 fruits per truss, and at the same time spray flowers with 30-50 micrograms/ml Tomatotone to prevent flower and fruit drop. After each truss has set fruit steadily, combine with watering and apply 15-20 kg of urea or compound fertilizer per mu as topdressing, then spray 2-3 times of potassium dihydrogen phosphate solution in divided applications. Starting in early December, add reflective film, which can increase light inside the greenhouse by 15%-20%, and at the same time raise the temperature inside the greenhouse by about 20°C, promoting tomato fruit enlargement. Increase yield. Every 2-3 weeks, spray pesticide once to prevent disease. Use procymidone to control gray mold; use chlorothalonil, carbendazim, thiophanate-methyl, mancozeb and other medicinal solutions to control early blight, late blight, leaf mold, and other diseases.
