Non-woven fabrics are widely used in agricultural projects

In recent years, a kind of widely used in construction, non-woven packaging and medical and health care, consumer goods, is being applied to vegetables, flowers, rice seedling and tea leaves, flowers on the frost damage prevention, replace and make up for the deficiency of the mulch on heat preservation. Now apply non-woven technology is introduced as follows: one, the product features non-woven fabric is a kind of has good air permeability, moisture absorption and transmission of light new cover material, with cold heat preservation, anti frost, prevent exposure to the sun, and so on. And light weight, corrosion resistance, long life, 4 - 5 years) , easy to use storage. White non-woven can coordinate the crop growth microclimate, especially in winter outdoor or greenhouse seedling and the temperature of the vegetable, nursery stock, the relationship between light and pervious to light; Summer can prevent the strong sunlight seedbed moisture evaporates quickly, seedling and vegetables, flowers, such as young seedlings of burns. Second, the use method 1, garden trees transplanting and provisonal planting. Before the large trees, small provisonal planting seedlings, but non-woven spread within the buffalos provisonal planting again first, and then covered with soil, in this way provisonal planting landscape plants survival rate is high, and water and fertilizer. 2, winter greenhouse and open field seedling ( Specifications for 25 - 30 g / 280 cm) Surface coverage. Can prevent wind and raise the temperature. Seedbed side covered non-woven compaction, the other side of the brick and soil compaction, make little tunnel can also be used bamboo or thick wire, and cover the non-woven fabric in the above, surrounded by brick or soil compaction. Coverage of vegetables, flowers, need more sunshine, jie do morning, evening cover. Surface coverage, 10 cm away from the earth's surface temperature can be improved about 2 ℃, improve the ground temperature 1 - 2 ℃, the vegetables 5 - early can be covered 7 days, improve the yield was about 15%. 3, for ceiling. In the greenhouse, greenhouse Zhang Yidao non-woven fabrics for ceiling, ceiling and plastics greenhouse film span 15 20 cm; To form a thermal insulation layer, can improve the relative temperature of 3 - 5 ℃, day and night closed, interlayer between must be tightly closed. 4, in a small tunnel outer covering ( Specifications 80 - 100 g / 280 cm) Careless, careless instead of insulation to use, than to save costs by 20%, greatly extend the service life; Also can be in a small tunnel cover a layer of non-woven fabric, then cover with plastic film, 5 - can improve the temperature 8℃。 5, for covering the sun. Directly with non-woven fabric cover on the bed, cover in the morning, in the evening, can effectively improve good seedling emergence, full stand. Vegetable, flower seedlings, the seedlings, summer can be covered in the miao directly. 6, before the cold wave comes in vulnerable to cold tea, flowers and other crops, with non-woven fabric cover directly, which can effectively reduce the frost damage loss.
