Recently, the Hunan Provincial Department of Agriculture and Rural Affairs Office issued the "Hunan Province 2023 Scientific Use and Recycling Pilot Work Implementation Plan".
During the implementation of the project, 2.5 million acres of thickened high-strength mulch films and 500,000 acres of fully biodegradable mulch films were promoted in key film-using areas in Hunan Province. The mulch film recycling rate in the pilot areas has stabilized at more than 83%.
In terms of financial support, the thickened high-strength mulch film is 34 yuan/mu, and the fully biodegradable mulch film is 70 yuan/mu.
The plan requires that scientifically promote high-strength thickened mulch films, select mulched crops according to local conditions, and give priority to open-air vegetables, fruits and other crops. Support the promotion of the use of high-strength thickened mulch films of 0.015 mm and above to ensure the safety of mulch films from the source. Recyclability.
Steadily promote fully biodegradable mulch films. Focus on selecting areas and crops where trials have been carried out, giving priority to tobacco leaves, refined vegetables and high value-added cash crops, and steadily promote fully biodegradable mulch films that comply with the national standard of "Fully Biological Agricultural Ground Covering Film" (GB/T35795-2017) (The main ingredients are biomass materials such as aliphatic polyester and aliphatic-aromatic copolyester with completely degradable characteristics. They must not contain polyethylene (PE), polypropylene (PP) and other olefin raw materials. An appropriate proportion of Starch, cellulose, etc., as well as other environmentally friendly inorganic fillers and functional additives). In principle, the water vapor transmission rate of the product is below 400g/(m2·24h), and the effective service life is more than 60 days. The specific indicators are determined by various localities based on crop types, production conditions, etc.
