Facility vegetable production ushered in the winter with less sunshine and low temperature. In order to make vegetables grow normally, growers should pay attention to the following aspects of management:

1. Insulation and antifreeze. Insulation is enhanced by a multi-layer cover. In order to ensure the temperature inside the vegetable shed, “two membranes” and “three membranes” can be added in the shed, and the multi-layer covering method of mulching film + small arch shed + greenhouse + straw curtain is adopted, and the rain curtain outside the shed is covered with “rain protection”. Membrane", can also be added around the greenhouse "apron" film, etc., can effectively keep warm, to prevent low temperature freezing damage. The straw curtain implements the practice of “covering the night and covering it early”. Generally, after the straw curtain is opened in the morning, it is better to remove the dust on the film and remove it in the rainy and snowy days. The straw curtain enhances the light transmittance. After 4 pm, the straw curtain is covered in time to save heat as much as possible to prevent heat loss at night and enhance the heat preservation effect.

2. Control watering and reduce the humidity in the shed. On the basis of watering in the early stage in winter, the principle of “five pouring and no pouring” is generally mastered, that is, “watering in sunny days, not pouring on cloudy days; watering in the afternoon, not pouring in the afternoon; pouring small water, not flooding; pouring warm water , do not pour cold water; dark water, do not pour water." So as not to reduce the ground temperature, increase the humidity of the air, cause disease; sunny should pay attention to ventilation, cloudy days should also be properly ventilated at higher temperatures. If the vegetables are short of water, you can choose the sunny weather just after the cold current, and use the method of submerged dark water or drip irrigation to avoid lowering the ground temperature.

3. Reduce fertilization and avoid vegetable roots. Winter vegetables grow slowly and need less fertilizer. Watering and topdressing should be reduced. If topdressing is required, the organic fertilizer and biological fertilizer should be used as the main fertilizer, and the fertilizer should be less as much as possible. When it is necessary to chase fertilizer, it is best to cooperate with drip irrigation to implement integrated management of water and fertilizer. It is also possible to choose sunny weather and cooperate with spraying anti-disease agents for foliar topdressing.

4. Strengthen management to ensure the growth of vegetables. It is necessary to clear the ditch and drain in the surrounding of the greenhouse and in the shed. If there is snow cover around the greenhouse, it is necessary to remove the snow in time, eliminate the water in the field, and try to reduce the environmental humidity of the greenhouse. Timely pruning and smashing to the old leaves, spraying some plant growth regulating protective agents, when controlling pests and diseases, use smoke agents or powders to control the disease.
