The "Soil Pollution Prevention and Control Action Plan" issued by the State Council a few days ago clearly proposes to promote clean agricultural production, carry out pilot projects for the resource utilization of agricultural wastes, and form a batch of replicable and popularized agricultural non-point source pollution prevention and control technology models. At present, China's agriculture has surpassed industry to become the largest non-point source pollution industry. For example, China accounts for 30% of the world's chemical fertilizer application, and the use of pesticides per unit area is twice as high as that of developed countries; about 2.5 million tons of agricultural film are applied every year, but less than 1.5 million tons are recovered, and about 1 million tons of waste agricultural film fragments remain in the soil. Rural non-point source pollution threatens rural ecology and farmers' lives.
