The use of needle punched non-woven fabrics in the agricultural field
1. Transplanting and fake planting of garden trees. Before fake planting of large trees and small seedlings, the polyester needle-punched non-woven fabric can be placed in the tree pits and then planted, and then covered with nutrient soil. This method has a high survival rate of fake garden trees, and retains water and fertilizer.
2. Use floating surface to cover the greenhouse and open field nursery in winter. Can prevent wind blowing and increase temperature. The seedbed is compacted with soil on one side of the needle-punched cotton, and the other side is compacted with bricks and soil. You can also use bamboo or thick iron wire to make a small arch, cover it with acupuncture non-woven fabric, and compact it with bricks or soil around it. Keep warm. Covered vegetables and flowers need more sunlight, so that they can be uncovered in the morning and covered in the evening. Covered vegetables can be put on the market 5-7 days earlier, increasing the yield by about 15%.
3. Used as a ceiling. In the greenhouse and greenhouse, a polyester needle-punched non-woven fabric is used to make the ceiling. The distance between the ceiling and the plastic greenhouse film is 15-20 cm; an insulation layer can be formed, which can increase the temperature in the greenhouse by 3-5°C. It is opened during the day and closed at night. The layers must be closed tightly to be effective.
4. Cover the small arch shed to replace the straw curtain for heat preservation, which saves 20% of the cost than the straw curtain and greatly extends the service life; it can also cover the small arch shed with a layer of polyester needle-punched non-woven fabric and then cover with plastic film , Can increase the temperature by 5-8℃.
5. Used for shading light. Cover the seedbed directly with polyester needle-punched non-woven fabric, cover it in the morning and uncover it in the evening, which can effectively improve the number of seedlings and the whole seedlings. Vegetables, flower seedlings, and middle seedlings can be directly covered on the seedlings in summer.
6. Before the cold wave comes, directly cover the crops such as tea and flowers that are susceptible to freezing damage with polyester needle-punched non-woven fabrics, which can effectively reduce the loss of freezing damage.
Polyester needle-punched non-woven fabrics have a wide range of applications. In addition to being used in agriculture, they can also be used in medical and health, clothing, toys, home textiles, shoe materials, and so on.
