Tomato is a common vegetable in the market and a vegetable that is often eaten in life. It has high economic benefits. In order to better improve economic efficiency and yield, it is also a good choice to use greenhouses in winter. Then, in the process of tomato planting, what about the hollow tomatoes in the greenhouse? What's going on? What are the preventive measures? Let's take a look!
1. The reason for the hollowness of tomatoes in the greenhouse in winter: the direct cause of the "hollowness" of tomatoes is that the temperature of the water in the greenhouse is lower than 7 ℃, and the roots of the tomato are contracted by cold, the vigor of the roots is reduced, and the water absorption is poor. In the short-term lack of water supply, the phenomenon of partial lack of flesh in the fruit is prone to occur. Although the ground temperature increased and the roots resumed water absorption, the hollow part of the enlarged fruit was no longer full. Therefore, the water temperature of greenhouse tomatoes in winter must be raised to 10°C in advance.
2. Prevention method: You can use a corner of the greenhouse to temporarily store watering water, and then water it after the water temperature rises, so that the "hollow" phenomenon of tomatoes can be avoided.
