How is non-woven cloth used in vegetable greenhouses?
As a new kind of mulch insulation material, non-woven cloth has been used in vegetable production in the shed and has achieved good economic benefits.
1. Keep warm. The transmittance of non-woven fabric is lower than that of plastic film for long wave light. Because the heat dissipation in the radiation area at night mainly depends on the long-wave radiation, so the effect of covering heat preservation is outstanding.
2. Air permeability and humidity control. Non - woven fabrics by filaments overlap into a network, has a high voidage, breathable, water permeable, automatic humidity regulation.
3. Shading and cooling. Color non - woven cloth covering, shading and cooling effect. Non-woven fabrics of different colors have different shading and cooling effects. Black is better than yellow, and yellow is better than blue.
4. Anti-aging. Agricultural non - woven fabric after anti - aging treatment, the thicker the fabric the lower the strength loss rate.
After the application practice of vegetable farmers, non-woven fabrics are mainly used in the following aspects in vegetable production in the shed:
Use it at the bottom of the grass cover as a "two-track" insulation material. Many rooftops of sheds not only cover grass coverings, but also add a layer of non-woven cloth at the bottom. According to the introduction of the vegetable farmers, through the addition of "two" insulation materials (non-woven cloth), can significantly improve the insulation performance of the shed, than the simple cover grass cover 2℃-3℃, so as to facilitate the growth of vegetables. In addition, in the use of the roll-up machine of the shed on the application of non-woven fabric, can also protect grass cover, extend its service life.
Used on the back wall of the greenhouse as a "slope protection" rainproof material. The whole back wall is sewed together with several non-woven fabrics and fixed with steel wire, which can reduce the heat loss of the back wall. Can prevent rain and snow, protect the wall; Can cover weeding, reduce pests and diseases into the shed damage.
Other applications. Used in the production of multi-film covered watermelon in early spring arch shed, the non-woven cloth can be directly covered on the small arch shed in the arch shed, the heat preservation and cold prevention effect is outstanding.
