1. Strengthen water and fertilizer management. Deeply plow the soil and apply more organic fertilizer so the plant's root system grows well. For late-autumn tomatoes, when temperatures drop sharply, pay even more attention to soil moisture management and avoid overly rapid moisture changes. In open-field cultivation, water more regularly to avoid drastic soil moisture changes when rain suddenly falls, and drain promptly after rain...

Key Technical Points for Preventing Spindly Growth in Greenhouse Tomatoes
The main causes of spindly seedlings and stunted seedlings in greenhouse tomato cultivation are insufficient light, excessively high temperatures and excessive moisture. Once spindly or stunted seedlings appear, the harm is considerable. Spindly seedlings differentiate flower buds late, drop many flowers, have a low survival rate, and suffer large yield reductions, while also failing to achieve early maturity. The measures to prevent spindly seedlings mainly...

Early prevention and control of gray mold in autumn tomatoes gives good results
Gray mold: During the flowering period, 0.1% of 50% procymidone wettable powder or 50% iprodione wettable powder can be added to the flower-dipping medicinal solution, with very good results. Spraying the fruit is also possible, but care should be taken to rotate the medications to prevent the pathogen from developing resistance. 50% duoke dust formulation can also be used, applying 1 kg of dust per mu.
