(1) Suitable temperatures during the day are 25 ° C to 28 ° C, and nights are 16 ° C to 18 ° C. (2) When the temperature is lower than 15 °C, tomato seed germination, pollination and fertilization and tomato turn red are affected. (3) When the temperature is lower than 10 °C, the growth is slow and the reproductive development is inhibited. (4) When the temperature is 5 °C, the stems and leaves stop growing, and at 2 °C, they are chilled and frozen at 0 °C. (5) Reproductive development is affected by temperature above 35 °C, and is more than 40 °C physiological disorder and heat death. 3. Management of water and fertilizer (1) Tomatoes generally do not need watering in the summer and autumn rainy seasons, but they will encounter drought when the second ear is ripe, and should be properly watered. (2) The tomato of the fertilized fertilizer is higher than the non-bacterial fertilizer, and its fruit color and sweetness yield are higher than several grades. (3) If the phenomenon of deficiency in the greenhouse is serious, it can be sprayed with foliar fertilizer and has special effects. 4. Prevention and control of pests and diseases (1) The disease of tomatoes can be prevented from being refractory, and should be based on "prevention".

(3) On-site sale or self-feeding should be picked at the maturity stage, that is, when the fruit is red or yellow. (4) It should be lightly picked and collected when picking up. It is best not to bring fruit stalks when picking up, in case the fruits are stabbed in each other during shipment. Note: It is not advisable to use hormones to stimulate fruit coloring in the post-fruit ripening period. The advantage is that it not only reduces production costs, improves the quality of tomatoes, but also ensures the safety of consumers. The above is the high-yield planting technology of tomatoes.
