Plastic film mulching planting is an important measure to solve the problems of drought and water shortage and agricultural water saving.However, in agricultural production, such mulching film has the problems of difficult recovery and difficult degradation, and the residual film in the soil accumulates year by year, causing the ecological environment to suffer Destruction, forming a large area of 'white pollution' Wang Pengfei CPPCC National Committee members believe that we should step up research and development support advanced recycling and reuse of residual film technology and equipment to ensure sustainable development of agriculture.
According to Wang Pengfei, according to statistics, the area covered by plastic film for agricultural use in our country reached 298 million mu in 2014. The area of application has expanded from the arid and semi-arid areas in the north to the high mountains and cool areas in the south, covering crop varieties from economic crops to bulk grains Crops In recent years, the problem of plastic film residue has become increasingly prominent, and the ecological environment of the soil and land have had serious damage.The existing waste film treatment methods are the following: First, recycling, but easy to damage due to ultra-thin plastic film , The recovery time-consuming and laborious, farmer initiative to recover residual film is not high; Second, buried, but buried in the local agricultural film, film degradation cycle is too long, will eventually cause deep pollution of the environment; Third, without any treatment, Wasted film was blown away; Fourth, burning, but release a lot of smoke and toxic substances, pollute the air.
Wang Pengfei proposed to further increase the advanced R & D support for the technology and equipment of residual membrane recycling and reuse, and to support the research and development of new degradable mulching materials and new products with better adaptability in the region and to subsidize users of degradable mulch film products. Legislation on legislation of prevention and control of agricultural film pollution According to the principle of 'who uses who recycling and who pollutes who is responsible', it restricts the production and use of the film by legal means.
