Degradable liquid film

A degradable liquid film that can replace plastic mulches was introduced in Beijing recently. Relevant experts believe that the successful development of biodegradable liquid mulches will play a huge role in inhibiting “white pollution” brought by plastic mulch film farmland, as well as in heat preservation and reduction of coastal zone loss. According to reports, this product is a high-tech product jointly developed by the China Academy of Agricultural Sciences, Beijing Yanshan Petrochemical Company and other units. It is a kind of emulsion that is mixed with special additives in the everywhere bitumen, and has a strong adhesive effect.

The black and brown black liquid film can increase the absorption rate of light and increase the soil temperature. Compared with plastic mulch, degradable liquid mulching has the following features: The first choice is easy to use. The liquid film only needs to be diluted 4-5 times with the original solution and evenly sprayed on the surface with a pesticide sprayer. The entire operation process can be completed by one person. Followed by no artificial rupture. After the liquid film is sprayed and dried to form a film, the plant seedlings can directly rupture the film without artificial rupture of the film. The third is natural degradation. The state-of-the-art membrane naturally degrades after it completes the functions of water retention, warming, soil conservation, and seedling conservation. After entering the soil, it can also exert its role as a soil conditioner and continue to exert its effect of improving the soil. ("Business Express")
