People engaged in the greenhouse industry in agriculture know that keeping the greenhouse dry is important. Scientists engaged in the design and research of greenhouse facilities can design and manufacture basic and modern automatic control greenhouses according to the different needs of users. So how do we get rid of the dampness in a multi story greenhouse to ensure the normal growth of plants?
1. Cover with plastic film. The use of plastic film covering can reduce soil moisture evaporation and is an important measure to reduce indoor air humidity. In addition, insulation curtain materials with good moisture absorption are used. The use of insulation curtain materials with good moisture permeability and absorption can prevent dew from falling on plants, thereby reducing the air humidity in multi greenhouse buildings.
2. Heating and dehumidification. This method can not only meet the temperature requirements of vegetables, but also reduce the relative humidity of the air. When the plant grows to the point of resistance, water and close the shed to raise the temperature to about 30 ℃ for 1 hour, then ventilate and dehumidify. After 3-4 hours, if the greenhouse temperature is below 25 ℃, it can be repeated once. Natural moisture absorption can also be achieved by using materials such as straw, wheat straw, and quicklime to spread between rows and absorb water vapor or mist, achieving the purpose of dehumidification.
3. Ventilation. Ventilation is a good way to reduce humidity, but ventilation must be carried out at high temperatures, otherwise it will cause a decrease in indoor temperature in multi greenhouse buildings. If the temperature drops too quickly during ventilation, the ventilation openings should be closed in a timely manner to prevent a sudden drop in temperature from harming the vegetables. So we need to control the ventilation situation well, otherwise the consequences will be unpredictable.
