Features greenhouses: the regulation of air humidity. Variation of greenhouse air humidity: plastic film closed strong agricultural greenhouses, greenhouse air with outside air exchange is hindered, soil evaporation and transpiration of water vapor foliage difficult diverge. Therefore, the construction of agricultural greenhouse, shed humidity. During the day, under greenhouse ventilation, air shed 70-80% relative humidity. After the rainy days or irrigation of up to 90%. Features greenhouses: the regulation of air humidity. Air humidity regulation: the greenhouse air humidity is too large, not only directly affect photosynthesis and the absorption of mineral nutrition of vegetables, but also conducive to spore germination and infection. Therefore agricultural greenhouse construction company, to conduct ventilation, promote shed humid air is exchanged with outside air humidity, can effectively reduce the relative humidity in the greenhouse.
