The direct cause of the tomato hollow is that the temperature of the water poured in the greenhouse is below 8°C. At low temperature, tomato roots are cold contracted, root activity is reduced, and water absorption is poor. If the tomato fruit is in an expansion stage and the water supply is short-term, it is prone to local meat loss. Although the ground temperature was later increased and the roots recovered their absorption capacity, the hollow part of the already enlarged fruit could no longer be enriched. Therefore, the greenhouse water temperature in winter must be raised to above 12°C in advance. The method is: You can make use of a corner of the greenhouse to temporarily store the water, so as to improve the temperature, and the tomato hollow phenomenon can be avoided.

The production of tomatoes in winter greenhouses is prone to external enlargement and hollow fruit, which not only directly affects the yield, but also greatly reduces the quality and taste of tomatoes.
