Guangdong agricultural non-woven fabric

The characteristics of Guangdong agricultural non-woven fabric

Insulation:

Non woven fabrics have a lower transmittance for long wave light than plastic films. Because the heat dissipation in the nighttime radiation zone mainly relies on longwave radiation, the coverage insulation effect is outstanding.

Breathable and moisture regulating:

Non woven fabrics are made by stacking long filaments into a mesh, with a high porosity, allowing for breathability, water permeability, and automatic humidity adjustment.

Shading and cooling:

Covering with colored non-woven fabric, it has a shading and cooling effect. Different colored non-woven fabrics have different shading and cooling effects. The shading effect of black is better than yellow, and yellow is better than blue.

Anti aging:

Agricultural non-woven fabrics have undergone anti-aging treatment, and the thicker the fabric, the lower the strength loss rate.

After practical application by vegetable farmers, non-woven fabrics are mainly used in greenhouse vegetable production in the following aspects:
Used as a “second layer” insulation material at the bottom of the straw cover. Many shantytowns not only cover their greenhouses with straw sheets, but also add a layer of non-woven fabric to the bottom of the straw sheets.

Application of Guangdong agricultural non-woven fabric

Agricultural non-woven fabrics have achieved excellent results in agricultural production due to their good water solubility, soil solubility, and breathability. They are widely used in agriculture, forestry, fruits, vegetables, flowers, and tobacco seedling cultivation.

1. Transplantation and planting of garden trees. Before planting large trees and small seedlings, non-woven fabric can be laid in the tree pit before planting, and then nutrient soil can be applied. This method of planting garden trees has a high survival rate and can retain water and fertilizer.

2. For winter greenhouse and open field seedling cultivation, use a floating surface cover (size 25-30g/280cm). Can prevent wind blowing and increase temperature. On one side of the seedbed, use soil to compact the non-woven fabric, and on the other side, use bricks and soil to compact it. Bamboo or coarse iron wire can also be used to make a small arch shed, covering the non-woven fabric on top, and using bricks or soil to compact and insulate the surroundings. Vegetables and flowers that need to be covered should be exposed to more sunlight and covered in the morning and evening. Covering with floating surface can increase the temperature by about 2 ℃ from the ground surface by 10 centimeters, and increase the ground temperature by 1-2 ℃. Vegetables covered with floating surface can be released 5-7 days earlier, increasing yield by about 15%.

3. Used as a canopy. Stretch a non-woven fabric canopy in the greenhouse and greenhouse, with a distance of 15-20 centimeters between the canopy and the plastic greenhouse film; Forming an insulation layer can increase the temperature inside the greenhouse by 3-5 ℃. It should be opened during the day and closed at night. The compartments must be tightly closed to be effective.

4. Covering the outside of the small arched shed (specifications 80-100 grams/280 centimeters) instead of using grass curtains for insulation, saving 20% of the cost compared to grass curtains and greatly extending the service life; You can also cover the small arched shed with a layer of non-woven fabric and then cover it with plastic film, which can increase the temperature by 5-8 ℃.

5. Used for shading from sunlight. Covering the seedbed directly with non-woven fabric, covering it in the morning and uncovering it in the evening, can effectively improve the quality of seedlings. Vegetables, flower seedlings, and medium seedlings can be directly covered on the seedlings in summer.
