Multi-span greenhouse features and dehumidification methods

The multi-span greenhouse is an upgraded existence of the greenhouse. In fact, it is a large greenhouse. The original independent single-room greenhouse is connected with the original independent single-room mode greenhouse with scientific means, reasonable design and materials. Or understood as a kind of expansion.

Multi-span greenhouse features:

1. Utilization of space Compared with traditional greenhouses, the use of space in multi-span greenhouses and greenhouses is a bright spot compared to traditional greenhouses, and their utilization area is much larger than that of traditional greenhouses.

2. In terms of management, it is more unified than traditional greenhouses, more scientific in operation, saves time and improves efficiency

Multi-span greenhouse dehumidification method:

1. Ventilation and dehumidification. Ventilation is a good way to reduce humidity. Ventilation must be carried out at high temperatures, otherwise it will cause the temperature in the multi-span greenhouse to drop. If the temperature drops too quickly during ventilation, the vents should be closed in time to prevent the vegetables from being harmed by a sudden drop in temperature.

2. Plastic film covering. The use of plastic film covering can reduce the evaporation of soil moisture, which is an important measure to reduce indoor air humidity.

3. Heating and dehumidification. This method can not only meet the needs of vegetables for temperature, but also reduce the relative humidity of the air. When the plant grows to be resistant, water the closed shed and raise the temperature to about 30°C for 1 hour, then ventilate and dehumidify. After 3-4 hours, it can be repeated once when the greenhouse temperature is lower than 25°C.

4. Adopt thermal insulation curtain material with good hygroscopicity. Thermal insulation curtain materials with good moisture permeability and moisture absorption, such as non-woven fabrics, can prevent condensation on the inner surface of the shed and prevent dew from falling on the plants, thereby reducing the air humidity in the multi-span greenhouse.

5. Natural moisture absorption. Rice straw, wheat straw, quicklime and other materials can be used to spread between rows to absorb water vapor or mist to achieve the purpose of dehumidification.
