Covering a large area of ??Greenhouse Greenhouse construction companies, land use fully, the greenhouse temperature high solar greenhouse construction, temperature stability, cushioning and strong. In order to strengthen the country's cold insulation solar greenhouse, raising the temperature inside the greenhouse at night to reduce heat radiation at night and the use of multi-layer film covering. Multilayered canopy cover is then covered with a layer or layers of thin-film solar greenhouse quotes, conducted within the cold, commonly known as the two-story screen. The two-story curtain opened the day by light at night and then covered with strict insulation. Interval of two-story screen and greenhouse film, usually 30-50 cm. 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, the need for ventilation, promote shed humid air humidity air is exchanged with the outside world, can effectively reduce the relative humidity in the greenhouse.
