地膜殘留污染防控技術(shù)現(xiàn)狀及發(fā)展趨勢
[Abstract]:Film mulching has become one of the most important materials in agricultural production in China. Film mulching has been widely used in the whole country, especially in the arid and semi-arid areas in the north and in the cool and alpine regions in the south. In 2015, the amount of plastic film was 1.455 million t, and the coverage area was 18.318 million hm~2.. Film mulching technology has made a great contribution to ensuring food safety supply in China. However, with the increasing of plastic film input and service life, a large amount of agricultural film remains in the soil, which not only seriously affects the sustainable development of agricultural production. Moreover, it poses a great threat to the safety and health of agricultural environment. Based on the analysis of the present situation of the key technologies for preventing and controlling the residual pollution of plastic film, such as the substitution of biodegradable plastic film, the use of one film and two (multi-purpose) films, and mechanized plastic film recovery, the technical measures and strategies to deal with the residual pollution of mulching film in the future are put forward. It provides scientific basis for rational application of plastic film mulching technology and prevention and control of residual film pollution.
