High-Yield Cultivation Techniques for Greenhouse Tomatoes
1. Establish a high-standard warm winter greenhouse
Temperature is the key factor in overwintering tomato production. In order to provide the necessary temperature conditions for tomato growth, it is necessary to establish a high-standard winter greenhouse with good insulation and fast heating.

If the leaves are not properly cared for, it can easily cause premature aging of the plant, resulting in low yield. For specific methods, you can refer to spraying an appropriate amount of warm water or white sugar water on cloudy and foggy days to increase leaf surface humidity.
