Air humidity regulation: (1) changes of greenhouse air humidity: plastic film closed strong, greenhouse air exchange with the outside air is hindered, soil evaporation and transpiration of water vapor foliage difficult diverge. So Henan greenhouse construction, greenhouse humidity. During the day, under greenhouse ventilation, greenhouse air relative humidity of 70-80%. After rainy days or irrigation of up to 90%. Shed air relative humidity is reduced as the temperature rises, often to 100% at night. Shed after cold wet air condenses into water film or droplets attached to the inner surface of the film or plants. (2) the regulation of air humidity: the greenhouse air humidity is too large, not only directly affects photosynthesis and the absorption of mineral nutrition of vegetables, but also conducive to spore germination and infection. Therefore, the need for ventilation, promote shed humid air is exchanged with outside air humidity greenhouses, can effectively reduce the relative humidity shed. Henan greenhouse warming greenhouse vegetables to the hotline can also reduce the relative humidity. Using drip irrigation technology, combined with mulching, reduce soil moisture evaporation, can greatly reduce the air humidity (about 20%). Greenhouse skeleton advantages are as follows: 1, small investment without having to build factories in Henan plastic greenhouses, small footprint, two-phase, three-phase power available, 3-5 people can produce. 2 full specifications can produce different specifications of products, cylindrical, oval, distance, shaped, solid type, hollow tubes. 3, see Lee quickly without high investment risk.
