In orchard management, weed control is a vital part. Weeds not only compete with fruit trees for nutrients, water and sunlight, but may also become habitats for pests and diseases, posing a threat to orchard ecology and fruit tree health. Weed control cloth, as a geotechnical material specially designed for horticulture, has become an effective nemesis of weeds under orchard trees through its unique functions and mechanisms.Weed control cloth is usually made of black or other dark materials, which can effectively absorb and block the sun's rays. When weed control cloth covers the surface of the orchard soil, it creates a dark environment that prevents weeds from photosynthesis. Photosynthesis is the process by which plants use sunlight, water and carbon dioxide to make food and energy. Without light, weeds cannot carry out normal physiological activities, their growth rate slows down, and they eventually wither and die. This shading effect is the primary mechanism by which weed control cloth prevents weed growth.In addition to the shading effect, weed control cloth also has a temperature control effect. During the high temperature period in summer, weed control cloth can block direct sunlight, reduce the temperature of the soil surface, reduce water evaporation, keep the soil moist, and facilitate the growth of fruit tree roots. In winter, weed control cloth can play a role in heat preservation, reduce the loss of soil heat, and provide a relatively stable growth environment for the roots of fruit trees. Although temperature control is not the main function of weed control cloth, it also plays a positive role in regulating the soil environment of the orchard, indirectly reducing the growth opportunities of weeds.More importantly, weed control cloth has a physical barrier effect. It usually has a certain thickness and strength, which can effectively prevent the roots of weeds from penetrating the cloth surface, thereby preventing weeds from taking root and growing in the soil. This physical barrier effect is the key to the long-term weed control effect of weed control cloth. Even if a small amount of weed seeds germinate on the weed control cloth, these weeds cannot grow steadily in the soil because their roots cannot penetrate the cloth surface, and they will eventually die due to lack of nutrients and water.In addition, the laying of weed control cloth can also increase the organic matter content and loose permeability of orchard soil. Weed control cloth covering the soil surface can reduce soil compaction caused by human trampling and mechanical operations, and is conducive to the activity of soil microorganisms and the decomposition of organic matter. These all help to improve soil structure, increase soil fertility and water retention capacity, and create better conditions for fruit tree growth.In summary, weed control cloth effectively prevents the growth of weeds under orchard trees through multiple mechanisms such as shading, temperature control and physical barriers. It can not only reduce the competition between weeds and fruit trees, improve the yield and quality of fruit trees, but also reduce the cost of orchard management, reduce the use of chemical herbicides, and protect the ecological environment. Therefore, in orchard management, the application of weed control cloth has broad prospects and important significance.
