Maintain soil moisture
The weed-proof cloth covering hinders the vertical evaporation of soil water, increases the resistance of water evaporation, makes the water migrate laterally, and effectively inhibits the ineffective evaporation of soil water. In the absence of precipitation, mulching with weed-proof cloth can effectively increase the soil water content in the soil layers at 5cm, 20cm and 40cm by about 13%-15%.
Improve nutrient utilization
In agricultural production, the use of weed-proof cloth can maintain suitable soil moisture in the rhizosphere of plants, promote the development of root systems, and facilitate the absorption of nutrients in the soil by crops. At the same time, the inhibition of weeds by the weed control cloth greatly reduces the competition of weeds for soil nutrients, so that crops can obtain more sufficient nutrients.
increase crop yield
The use of weed control cloth for weed control in agricultural production provides a suitable growth environment for crops, greatly improves the nutrient utilization rate, and is conducive to the improvement of crop commodity quality and the increase of yield.
control weeds
The black weed-proof cloth can block the weeds from receiving sunlight, and its sturdy structure cannot penetrate the weeds, hindering their photosynthesis, so as to achieve a good weeding effect. Especially in the hills and mountains, the ground is uneven and there are many stones. It is difficult to implement measures such as mulching, weeding, and artificial weeding. The weed control cloth shows great advantages. Studies have shown that weed control cloth can almost completely inhibit weed growth and has advantages over other chemical or non-chemical weed control methods.
Prevent soil and nitrogen loss
Nitrogen in the soil, especially inorganic nitrogen, exists in large amounts in the soil solution. When the rainfall is large, surface runoff is formed under the erosion of the rainwater. Nitrogen is lost with the runoff, and the soil is also severely eroded. Slopes with high vegetation coverage can effectively reduce soil erosion due to root fixation, but in cultivated land a large number of weeds and other vegetation are removed, and soil erosion is easy. Laying grass-proof cloth can avoid the direct scouring of the soil by rain, maintain water and soil, prevent nitrogen loss, and protect the ecological environment.
Physical control of pests
In agricultural production, many pests use weeds as their habitats, and the use of weed-proof cloth can effectively control weeds and reduce the source of pest infestation. The use of grass-proof cloth can also effectively prevent pests such as borers and moths that overwinter in the soil, reduce the application of pesticides, help increase crop production, improve the safety and commerciality of agricultural products, and can meet the national requirements for creating vegetable and fruit gardens. production needs. Compared with mulch film, grass-proof cloth has better air permeability, which can effectively avoid root rot in the use of mulch film. The functional weed-proof cloth made of the inter-color warp knitting method can effectively prevent and control pests such as aphids by utilizing the evasion of pests.
