Three, the role of grass cloth
Horticultural ground cloth is also known as "grass-proof cloth", "ground woven film", "ground protection film" and so on, mainly used for greenhouse ground weed control, drainage, keep the ground clean, ground marking and guidance purposes.
1, prevent weeds on the ground. Because the floor cloth can prevent the direct sunlight to the ground (especially the black floor cloth), at the same time, the use of the floor cloth itself strong structure to prevent weeds from passing through the floor cloth, thus ensuring that the floor cloth to weed growth inhibition.
2, eliminate the ground water in a timely manner and keep the ground clean. The drainage performance of the cloth ensures the rapid discharge of the ground water, and the cobble layer and medium sand layer under the cloth can effectively inhibit the reverse osmosis of soil particles, thus ensuring the surface of the cloth is clean.
3, is conducive to the growth of plant roots, to prevent root rot. This effect also stems from the weaving and laying structure of ground cloth, which ensures that no water accumulates in the roots of crops, so that the air in the roots has a certain fluidity, thus preventing root decay.
4, prevent the extra growth of potted flower roots and improve the quality of potted flowers. When potted flowers are produced on the ground, the ground cloth can prevent the roots of the plants in the pot from penetrating the bottom of the pot and drilling into the ground, thus ensuring the quality of potted flowers.
5. Favorable to cultivation and management: Most of the ground cloth is woven with one-way or two-way marker lines, in the greenhouse or outdoor pots or arrange cultivation substrate, according to these marker lines to accurately arrange.
It can be used in weed control, greening, water conservancy, dam construction, road construction, airport, construction, environmental protection projects, reclamation and land reclamation. It can play the role of filtration, drainage, isolation, protection and reinforcement.

1. Characteristics of grass proof cloth:
1, high strength, due to the use of plastic flat wire, in the dry and wet state can maintain full strength and elongation.
2, corrosion resistance, in different pH and soil and water can be corrosion-resistant for a long time.
3, the permeability is good in the gap between flat wire, so it has good water permeability.
4. Good resistance to microorganism and moth.
5, construction is convenient, because the material is light and soft, so transportation, laying and construction are convenient.
6, high breaking strength, up to 20KN/m, good creep resistance and corrosion resistance.
