For greenhouse vegetables, ensuring the safety of greenhouses is one of the most basic measures. Wind and snow weather will inevitably occur in winter weather, so at this time, the greenhouse should be reinforced, such as pressing the laminating rope, and pressing the two sets of fine steel cables in the lateral direction of the grass and the outer membrane. It can effectively prevent the wind from blowing up the grasshopper together with the outer film. On snowy days, a layer of anti-snow film should be applied to the haystack, and cleaned up in time after snowing. In order to prevent the shed from collapsing, a column should be added to the front of the shed to reinforce the shed.

Therefore, if you want to grow good fruits and vegetables in the greenhouse, you should ensure that the temperature in the greenhouse is appropriate. How to do it? At this time, when the grasshoppers play their role, it is necessary to "late the early cover" to maintain a relatively constant stability in the greenhouse.

Watering in winter should pay attention to not watering in the deep winter season to prevent freezing damage, but should choose to use drip irrigation under the membrane, micro-sprinkling or pouring water under the membrane in fine weather. At the same time, due to the weather factor, the vegetables grown in winter generally grow slowly, so the demand for fertilizer is relatively small. At this time, some organic fertilizer or biological fertilizer should be topdressed.
4. Disease prevention
The greenhouse is relatively a closed space, so it is especially important for the prevention and control of pests and diseases. To reduce the occurrence of vegetable diseases in the solar greenhouse, it is necessary to minimize the humidity of the air in the greenhouse. When using drugs to control vegetable diseases, try to use dust or aerosol.
