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 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, combined with mulching cultivation, reduce soil moisture evaporation, can greatly reduce the air humidity (about 20%). As a non-woven non-woven needle shed, both breathability and insulation, fruits and vegetables in the nursery have played a positive role. Here is the introduction to the specific characteristics of non-woven fabrics shed: 1, light weight: the polypropylene resin as the main raw material of electric insulation is, the proportion of only 0.9, only three-fifths of cotton, with fluffy, feel good. 2, soft: the fine fibers (2-3D) tap hot-melt adhesive molding. Finished moderate softness with comfort. 3, water repellent, breathable: the promotion of non-absorbent polypropylene insulation is sliced, the moisture content is zero special insulation, water-repellent finished good, with fibers from 100% porosity, permeability, and easy to maintain the fabric dry, easy to wash. 4, non-toxic, non-irritating: product is in compliance with FDA food-grade raw material production, without other chemical composition, stable, non-toxic, odorless, does not irritate the skin. 5, anti-bacterial, anti-chemical: Polypropylene is a chemical substance blunt, no insects, and can isolate the bacteria and insects liquid erosion exist; antibacterial, alkali corrosion, erosion and the finished product is not due to the impact strength.
