Humidity control: First, mulch film covering in the shed to reduce evaporation of soil moisture in the shed; second, timely and proper watering, watering should be ventilated and ventilated on a sunny morning, noon, and water vapor; three attention to ventilation and ventilating, without affecting the shed In the case of internal temperature conditions, ventilate early and regularly. Ventilation is required not only on sunny days but also on rainy days. It is an important technical measure for winter management to improve the light in the shed by controlling the light in various ways. It is necessary to remove dust, snow and water droplets and water mist from the surface of the shed film at any time. Always keep the shed film clean and transparent, and improve the light transmission of the shed film. rate. In addition, under the premise of not affecting the temperature, the straw curtain should be lifted as early as possible to extend the light time of the vegetables.

Multi-layer cultivation technology is usually used for temperature regulation production, that is, covering the ground with plastic film to increase the heat capacity of the soil; covering the grass curtain with a straw curtain, and covering the grass curtain with a layer of plastic film to prevent rain and snow from wetting the grass Curtain, effectively increase the temperature in the shed. Through such multiple coverings, the temperature in the greenhouse can be increased by 3 ° C to 5 ° C, which has a good effect of preventing cold and heat.
