When growing vegetables in greenhouses, you should first pay attention to leveling the land, renovating and weeding, and adding some base fertilizer at the same time. When setting up a shed, find a good location and control the size. Choose vegetables that are shade tolerant, disease resistant and high humidity tolerant. They are more suitable for growing in a greenhouse environment. The temperature should be controlled and should not be higher than 33℃. Watering is best done using drip irrigation.
1. Leveling the land
1. Leveling the land
The first step in greenhouse vegetable cultivation is to level the land. The land needs to be renovated and weeded, and some base fertilizer can also be added to the soil according to the vegetables grown. Fertilizer should not be too concentrated, otherwise it will cause deterioration such as soil hardening.
2. Set up a shed reasonably

At the same time, it is necessary to choose a suitable steel stand to provide better support. Choose non-drip film to cover the shed surface, which can increase the internal temperature.
3. Vegetable Selection

The first is that the lighting requirements are low, and the lighting time itself is not long in winter. In addition, the cover of the greenhouse will reduce the entry of sunlight, so be sure to choose shade-tolerant vegetables. The second is strong resistance. The ventilation capacity of the greenhouse is average, so the plants must have the ability to resist diseases. The third is resistance to high humidity. The humidity in greenhouses is often very high and difficult to control, so vegetables must be resistant to high humidity.
4. Temperature control
Greenhouse One of the biggest advantages is that it has good heat preservation properties, so that it can provide a growing environment for some vegetables. However, the temperature should not be too high and should be controlled below 33°C. When the temperature is higher than this, the temperature should be cooled down immediately and the shed can be opened for ventilation.
5. Drip irrigation and watering
Due to the high humidity in the greenhouse, it is not advisable to water too much. Generally, drip irrigation is better. Drip irrigation itself also saves water, making it an economical and cost-effective method.
