[0002] Biodegradable film is a new type of environmental protection material. Its main components are materials that can be completely degraded by the action of microorganisms in the natural environment, such as PBAT, PLA, etc. At the same time, environmentally friendly additives that are harmless to the environment are added. This kind of film can be degraded in the soil, avoiding the problem of residual film pollution generated during the use of traditional polyethylene (PE) plastic films, and having a protective effect on the soil structure and ecological environment. Plastic films, usually transparent or black PE plastic films, and there are also green and silver plastic films, are used for ground covering to increase soil temperature, maintain soil moisture, maintain soil structure, prevent pests from attacking crops and diseases caused by certain microorganisms, etc., and promote the growth of plants. In practical applications, scientific researchers optimize the formula and application method of biodegradable films according to the soil characteristics and remediation needs of different regions to achieve the best soil remediation effect. For example, in the remediation of saline-alkali land, specific microbial treatment technologies can be combined with the use of biodegradable films to reduce the soil salt content and improve the agricultural production capacity of the soil.
