Acupuncture needle felt insulation was: This is a very long life insulation, carpet layers made with recycled cotton insulation was quoted, tension increased. Filaments felt thick quilt more than cloth, not afraid of sun exposure, but because the density is relatively large, and therefore made thicker, heavier, insulation can be achieved, in the winter when wet will become heavy, and difficult to dry, This is a lot of users often complain about. Air humidity regulation: the greenhouse air humidity is too high insulation purposes, 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 humidity and ambient air is exchanged for insulation, can effectively reduce the relative humidity in the greenhouse. Hotline to shed heat, but also can reduce the relative humidity. Using drip irrigation technology promotion insulation is combined with mulching cultivation, reduce soil moisture evaporation, can greatly reduce the air humidity (about 20%). Insulation was quoted Tibet insulation was widely St. agricultural machinery provided by the Canton of St. Shouguang Agricultural Machinery Co., Ltd ..
