Weed barrieris a material that can increase the ground temperature and retain water

Weed control fabric is a technique that uses plastic or non-woven fabric to cover the soil or crops in the agricultural planting process, which can prevent weed growth, maintain soil moisture, increase soil temperature and crop yield. Weed control fabric has various types, such as black, white, silver, double color, perforated, film-covered, etc., and different types of weed control fabric have different characteristics and functions. The function and advantage of weed control fabric are mainly reflected in the following aspects:
· Weed control effect: Weed control fabric can effectively inhibit weed growth, reduce weeding workload and cost. Weeds are a big problem in agricultural production, they compete with crops for nutrients, water and light, affect crop growth and development, reduce crop yield and quality, and also increase the occurrence of pests and diseases. Weed control fabric can effectively prevent weed germination and growth by shading, isolating, suppressing and other ways. Different colors and materials of weed control fabric have different effects on weed control, generally speaking, black weed control fabric has strong shading property, which can effectively inhibit weed growth; white or silver weed control fabric has strong reflectivity, which can increase light intensity and promote crop photosynthesis; double color weed control fabric combines the advantages of black and white or silver, which can both shade and inhibit weeds, and also reflect and increase light.
· Water conservation effect: Weed control fabric can reduce water evaporation, maintain soil moisture, and save irrigation water. Water is an indispensable factor in agricultural production, it directly affects crop growth and yield. Weed control fabric can reduce water evaporation by covering the soil surface, reducing the contact area between water and air, lowering the water evaporation rate, and increasing soil water content. Different types and thicknesses of weed control fabric have different effects on water conservation, generally speaking, film-covered weed control fabric has strong water conservation property, which can effectively reduce water evaporation; perforated weed control fabric has certain water permeability, which can maintain soil aeration and infiltration; non-woven weed control fabric has strong water absorption and moisture retention property, which can absorb water from the air and release it to the soil.
· Warming effect: Weed control fabric can increase soil temperature, promote crop germination, growth and maturity. Temperature is one of the important environmental factors in agricultural production, it directly affects crop metabolism and physiological functions. Weed control fabric can increase soil temperature by covering the soil surface, increasing the soil’s absorption and storage capacity of solar radiation. Different seasons and regions of weed control fabric have different effects on warming effect, generally speaking, winter or cold regions use black or double color weed control fabric can effectively increase soil temperature, extend growing season, improve crop earliness; summer or hot regions use white or silver weed control fabric can effectively lower soil temperature
