Regulate the temperature in the shed: In winter, tomatoes are most likely to produce stiff fruit, especially in the long-term rainy and snowy weather, less light, high night temperature, less nutrients produced by tomato leaves during the day, and nighttime consumption is large, often forming more rigid fruit . In this case, the night temperature can be lowered to 10 ° C ~ 12 ° C, so that the tomato is maintained at the lowest growth temperature to reduce nutrient consumption, can reduce the occurrence of dead fruit.
Pay attention to reasonable fertilization and watering: if the fertilizer supply is insufficient, the plant grows poorly, or the fertilizer is too abundant and the plant grows prosperously, which is easy to cause the occurrence of dead fruit. Especially in the late growth stage of the tomato, it is necessary to spray the fruit and fruit to provide nutrients for growth. In particular, pay attention to make up the potassium fertilizer to avoid the large amount of fruit in the tomato due to lack of fertilizer.
