Biodegradable Agricultural Mulch Film Gains Popularity in Farmlands, Tackling "White Pollution" and Promoting Green Agriculture
"In the past, we worried about residual mulch polluting the soil and had to spend extra time and effort cleaning up the leftover film after harvest. Now, with biodegradable mulch, there’s no need to clean it up—it naturally breaks down in the soil and even acts as organic fertilizer.
"In the past, we worried about residual mulch polluting the soil and had to spend extra time and effort cleaning up the leftover film after harvest. Now, with biodegradable mulch, there’s no need to clean it up—it naturally breaks down in the soil and even acts as organic fertilizer. It’s incredibly convenient!" Recently, in a vegetable greenhouse in Shouguang City, Weifang, Shandong Province, vegetable farmer Li Guiying pointed to the newly laid mulch film while sharing her experience with a reporter. As the concept of green agriculture gains traction, biodegradable agricultural mulch film, with its environmental advantages, is rapidly being adopted across farmlands nationwide, offering an effective solution to "white pollution" in agriculture.
It is understood that traditional polyethylene mulch film is difficult to degrade, and its long-term accumulation can damage soil structure and hinder crop growth. In contrast, biodegradable agricultural mulch film is made from renewable resources such as corn starch and plant fibers, allowing it to decompose completely into water and carbon dioxide in the natural environment without leaving any residue. Under the promotion of Shouguang City’s Agriculture and Rural Affairs Bureau, five demonstration bases for biodegradable mulch film have been established locally, covering an area of 80,000 mu. These bases support facility-grown vegetables such as cucumbers, tomatoes, and peppers. Monitoring data from the bases show that in fields using biodegradable mulch film, soil organic matter content has increased by 1.2 percentage points compared to fields using ordinary mulch film. Additionally, vegetable quality has significantly improved, commanding a market price 0.5 to 1 yuan higher per jin. Relevant officials from the Agriculture and Rural Affairs Department stated that the next steps will involve intensifying research, development, and promotion of biodegradable agricultural mulch film, introducing subsidy policies to reduce farmers' usage costs, and advancing the coordinated development of agricultural production and ecological conservation.
