Effective prevention of greenhouse hollows
During the production of tomatoes in winter greenhouses, there are prone to external enlargement and hollow fruit, which not only affects the yield, but also greatly reduces the quality and taste of the tomato. The direct cause of the tomato hollow is due to the fact that the temperature of irrigation in the greenhouse is below 7°C. At low temperatures, tomato roots are cold-shrinked, root vigor is reduced, and water absorption is poor. At this time, the results of the breeding process are in a period of expansion. In the short-term lack of water supply, the phenomenon of local flesh-eaten fruit is prone to occur. Although the ground temperature was later increased, the roots recovered water, but the hollow part of the expanded fruit could no longer be enriched. Therefore, in the late fall and winter, when the greenhouse tomato is poured, the water temperature must be raised to above 10°C in advance (the temporary water can be used in the corner of the greenhouse to facilitate temperature increase), and the tomato hollow phenomenon can be avoided.
