with the development of facility agriculture and the wide application of plastic film mulching technology, the non-point source pollution caused by waste agricultural films is becoming more and more serious. The amount of agricultural film is also increasing, and the residual amount of waste agricultural film in the soil is increasing year by year. China should increase the recycling of agricultural film.

some data show that China's agricultural film is increasing at a rate of 10% per year, and has now exceeded the 100 million mu mark, with the amount of agricultural film pollution increasing. However, the agricultural residual film is a polymer compound polyethylene or polyvinyl chloride, which is a plastic that is difficult to degrade, has a high melt index and a degradation cycle of 200 ~ 300, and toxic substances will be dissolved in the degradation process.

If the agricultural film is left in the soil, the first is the harm to the soil, which weakens the drought resistance of the cultivated land and reduces the soil fertility level; The second is the harm to crops, which will destroy the physical and chemical properties of the soil, cause difficulties in the growth and development of plant roots, affect the normal absorption of fertilizer efficiency, and lead to a decline in yield; Once again, the harm to livestock, if cattle and sheep eat residual membrane by mistake, blocking esophagus will affect digestion and even lead to death; Of course, its damage to the rural environmental landscape is also fatal: colorful discarded agricultural films are littered everywhere, which is really unbearable.

It is known from local media that the urban environment has been greatly improved, but environmental protection is still a blank in most rural areas. On January 7 last year, Nanfang Daily reported: 'garbage and waste water surround the countryside, and the countryside is environmentally friendly. 'Forgotten Corner''; The year before last, 'Red Net' also reported: 'Garbage surrounds the countryside, Taojiang county's environment is in emergency. ' The countryside of Taojiang county used to be a good place with lush trees and birds and flowers. Now, don't say fish and shrimp, even the mud can't be found. Garbage has become a mountain and the environment is harsh, especially agricultural film pollution, which has become a very important and urgent issue concerning agricultural ecological security and sustainable development. In fact, the agricultural film is recyclable, and its recycling uses are quite a lot. Therefore, as long as the government does this recycling work well, the agricultural film pollution can be completely avoided, on March 22, 2012, Premier Wen Jiabao stated in the 'important information items' of the National Audit Office: it is necessary to do a good job in the recycling of agricultural plastic film.

'Min sheng wu small' Concerned about rural environmental protection issues, paying attention to the living environment of farmers, and paying attention to the life and health of farmers, this is the real livelihood event. To this end, our governments at all levels must first strengthen publicity and education, improve the farmers' long-term and seriousness of the damage of plastic film pollution, and enhance the awareness of environmental protection; Secondly, it is necessary to establish an incentive mechanism and increase recycling: Formulate some preferential policies to encourage the development of enterprises that recycle, process and utilize waste plastic film. This is the fundamental solution to curb agricultural film pollution.
