Greenhouse insulation. 1). Multilayer insulation covering technology to improve nighttime temperature inside the greenhouse electric insulation was effectively overcome barriers to low temperature in winter. Multi-layer insulation covering insulation measures are cost-effective. 2). Stamped cover material. Stamped inside the shed covered with insulation materials such as straws, shade net. 3) control the ventilation time. Ventilation late morning, early afternoon covering film. 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 insulation was to promote shed humid air with the outside air relative humidity exchange, can effectively reduce the relative humidity in the greenhouse. Agricultural greenhouse insulation was heated to the hotline, 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%). Farm insulation was, insulation was widely St. agricultural machinery provided by Shouguang Agricultural Machinery Co. St. Canton. Shouguang City, Canton St. Agricultural Machinery Co., Ltd.
