In recent years, a non-woven fabric widely used in construction, packaging, medical and sanitation, and daily consumer goods is being applied to vegetables, flowers, rice and other seedlings and tea and flowers to prevent freezing damage, replacing and making up for plastic film covering and thermal insulation. On the shortcomings. Now the non-woven application technology is introduced as follows:
1. Product Features
Non-woven fabric is a new type of covering material with good air permeability, moisture absorption and light transmittance, which has the functions of preventing cold and heat preservation, frost prevention, and sun exposure. And light weight, corrosion resistance, long life (4-5 years), easy to use and store. White non-woven fabric can coordinate the growth of crops and the microclimate, especially the relationship between the temperature, light and light transmission of the open field or greenhouse seedlings and vegetables and seedlings in winter; summer can prevent the hot sun from causing rapid evaporation of seedbed water, uneven seedlings and vegetables and flowers Wait for the burns of the young seedlings.
2. How to use
1. Transplanting and fake planting of garden trees. Before fake planting of large trees and small seedlings, the non-woven fabrics can be spread in the tree pit 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. Floating surface covering for greenhouse and open field nursery (specification 25-30g/280cm) in winter. Can prevent wind blowing and increase temperature. On one side of the seedbed, the non-woven fabric is compacted with soil, and the other side is compacted with bricks and soil. You can also use bamboo or thick iron wire to make a small arch shed, cover the non-woven fabric on it, and use bricks or soil to compact the surrounding area for heat preservation. Covered vegetables and flowers need more sunlight, so that they can be uncovered in the morning and covered in the evening. Covering with floating surface can increase the temperature of 10 cm from the ground surface by about 2°C, and increase the ground temperature by 1-2°C. The covered vegetables can be put on the market 5-7 days earlier, increasing the yield by about 15%.
3. Used as a ceiling. A non-woven fabric is used as a ceiling in greenhouses and greenhouses. 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 shed by 3-5°C. It is opened during the day and closed at night. The compartments must be Close tightly to be effective.
4. Cover the outside of the small arch shed (specification 80-100 g/280 cm) 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 be covered with a layer of no Spun cloth and cover with plastic film can increase the temperature by 5-8℃.
5. Used for shading light. Cover the seedbed directly with 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 non-woven fabrics, which can effectively reduce the loss of freezing damage.
