What is the old farmer's wish weed cloth

While traditional PE mulch has made a great contribution to agricultural production, it has also caused a century of pollution to the soil and the environment due to its non-degradable chemical composition, which has brought serious harm to the sustainable development of agriculture. Although the technology research of photodegradable mulch and biodegradable mulch developed by domestic and foreign manufacturers has made progress, due to the technology and raw materials, the problem of natural degradation has not been broken. Most of the degradation is only superficial degradation. The chemical components added by degradation remain in the soil and cannot be eradicated. After long-term cracking and accumulation, the harm of invisible chemicals to the soil, groundwater and crops cannot be controlled. Although some manufacturers’ raw materials do have degradable conditions, in order to meet the relevant technical requirements of mulch, cooking or adding chemical additives for post-treatment during the production process will cause varying degrees of pollution to the surrounding environment. Due to the use of chemical The substance also has serious harm to soil and crops in use. The old farmers wish that the grass-proof cloth does not add any harmful chemical agents. After use, it will naturally degrade to form humus, which is non-toxic and does not pollute the environment after degradation, and it can also improve the structure of the soil. The old farmer wishes the grass-proof cloth adopts a new production process, which has the characteristics of breathable, hydrophilic, environmentally friendly and degradable, which overcomes the shortcomings of traditional plastic mulch films, such as dead vegetables and fruits, and non-degradable. The old farmers wish that the grass-proof cloth has a variety of physiological and ecological effects, such as ventilation, temperature increase, moisture preservation, no-tillage, fertilizer, prevention and reduction of pests and diseases, etc., which can increase the survival rate of crops, accelerate growth, and improve fruit quality; It has the functions of saving electricity, labor, fertilizer and pests and diseases.
