Because waterproof insulation is required Uncovery day, frequent unwinding and pulling work, resulting in a needle is too large, then the needle is too large have risks? Today, we briefly introduce. Waterproof insulation at the eye of a needle will be seepage, if it rains or snows weather industrial insulation was, rain and snow will be very easy to enter into the waterproof insulation insulation core is allowed to damp insulation core, and reduce its thermal insulation properties, and some are of waterproof insulation materials are waterproof insulation material is use, so enter the insulation core is unable to discharge the water through the eye of a needle. So easy to make long-term use waterproof insulation was lost due to damp insulation properties, affecting the normal growth of the crop. 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 supply insulation was to promote shed humid air with the outside air relative humidity exchange, can effectively reduce the relative humidity in the greenhouse. Hotline to shed heat, but also can reduce the relative humidity. Using drip irrigation technology, combined with mulching cultivation, reduce soil moisture evaporation, can greatly reduce the air humidity (about 20%). Greenhouse insulation was, Shanxi insulation was widely St. agricultural machinery provided by the Canton of St. Shouguang Agricultural Machinery Co., Ltd ..
