The ability of grass-proof cloth to keep soil moisture and water permeability is an important technical indicator of grass-proof cloth. It refers to the amount of water permeated within a certain period of time per unit area and reflects the ability of the grass-proof cloth to seep through the surface. It is used in orchards. The grass-proof cloth usually requires water permeability ≥5.0L/(S?m2). Similar to the conservation non-woven fabric, the anti-grass cloth cover blocks the vertical evaporation of soil moisture, allows the water to migrate horizontally, increases the resistance to water evaporation, effectively inhibits the ineffective evaporation of soil moisture, and the inhibitory effect increases with the anti-grass cloth cover Increased area increases. Practice has proved that under the condition of no precipitation, black plastic mulch and black grass-proof cloth can increase the soil moisture content of 20 and 40 cm soil layers by 13% to 15%, and the two have the same moisture retention effect. Agricultural drip irrigation, irrigation, and rainwater can penetrate into the soil through the grass-proof cloth, increasing the soil moisture; the black plastic ground cloth is impermeable and impermeable, and cannot penetrate the irrigation water into the soil. The practice of grass cloth mulching shows that grass cloth mulching not only controls weeds but also reduces soil moisture evaporation, and at the same time, it increases soil moisture.

Weed-proof cloth can improve soil nutrient utilization. After laying the weed-proof cloth, the soil moisture of the tree tray can be maintained, the surface area of the root system of the plant is increased, and the ability to absorb nutrients is enhanced. Farmers’ use of soil nutrients in the cherry orchard after laying black grass-proof grassland, the 5-year test results showed that the plant N, P, K, Ca, Mg, B, Zn, Mn, Cu and other nutrient elements significantly increased. Therefore, it is necessary to increase the fertilizer supply of the plants to ensure the rapid growth of the plants.

Weed-proof cloth can increase crop yield. After the orchard is covered with wed-proof cloth between rows, soil moisture is guaranteed, nutrient utilization rate is also improved, and crop yields such as fruits will inevitably increase. Covering grass-proof cloth significantly increases the output of apple orchards, citrus orchards, and dragon fruit orchards, as well as the growth of seedlings, flower gardens and other fruit trees. A 6-year apple orchard study showed that the nutrient element content of the leaves changes with the growing season after being covered with black turfgrass cloth; tree vigor and yield are higher than that of orchards without turfgrass cloth.
The grass-proof cloth can effectively control the weeds in the orchard. The black grass-proof cloth can prevent direct sunlight to the ground. At the same time, its strong structure can prevent weeds from passing through the grass-proof cloth, thus ensuring that the grass-proof cloth is effective for the growth of weeds. Inhibition. Especially in the hilly orchard, the ground is uneven, there are many rocks, plastic mulch, artificial weeding and other measures are difficult to achieve. The grass-proof cloth shows great advantages in controlling weeds. Many studies have shown that laying black grass-proof cloth between rows of orchards almost completely controls the growth of weeds and has advantages over other chemical or non-chemical weeding methods.

The grass-proof cloth can prevent the loss of water, soil and nitrogen. The loss of soil nitrogen, especially organic nitrogen, is actually the result of the interaction between slope runoff and soil nitrogen. Mountain orchards with large slopes are prone to surface runoff under the erosion of rainwater, causing serious soil erosion and nitrogen loss. On the slopes with high vegetation coverage, soil erosion is relatively reduced due to root fixation. The laying of weed-proof cloth can avoid the direct erosion of the soil by rainwater, maintain the water and soil, and prevent the loss of nitrogen.
