1. When the soil temperature is higher than 28 ℃, the resistance to root knot nematode gene decreases. Please use drugs as appropriate in the high temperature season. It is recommended to grow seedlings in soil or substrate.

2. At the flower bud differentiation stage of 2-6 leaves, the night temperature should not be lower than 12 ℃. The seedling age should not be too long, 50-60 days in spring and 25-30 days in summer. In spring, the night temperature of seedbed is specially increased. Strong seedlings are specially cultivated in summer.

3. After planting, do everything possible to promote root development and spray drugs to promote root growth, such as cytokinin, EM bacteria, etc. The slow seedling water should be properly supplemented with quick acting fertilizer. For high fertilizer cultivation, the first water after fruit setting shall be poured in time and early, and then it shall be promoted to the end. During fruit development, more foliar fertilizer shall be applied.

4. Reasonable close planting, plant spacing 33-35cm, row spacing 60cm. Single pole pruning, pay attention to thinning flowers and fruits, and leave three to four ears of fruits. Individual two panicle capped plants can leave terminal buds to continue to grow. Each plant has 10-12 fruits, and the average single fruit weight can reach 250-350g.

5. In most areas of northern China, tomato leaf mold has mutated, Jinpeng No. 1 has been infected, and m158 should also pay attention to leaf mold control. Baolian made in Japan has better efficacy.
