Mechanized recycling of mulch film in Chabuchar, Xinjiang, reduces soil “white pollution”

The film mulching cultivation technology department has greatly promoted the continuous increase of agriculture since it was promoted and used in Chabuchaer County, Xinjiang in the 1980s. However, the mulching cultivation technology brings significant benefits and is also used year after year. The mulch film can not be recovered in time, and the soil is ploughed every year and accumulated in the tillage layer, resulting in serious residual film pollution of the cultivated land, which brings potential harm to agricultural production, especially cotton production. Clearing the residual film has reached an urgent point, and "white pollution" has also attracted the attention of the county leaders. This year, the county implemented mechanized operations on residual membrane recycling, effectively reducing soil white pollution and increasing agricultural output.

Agricultural mulch polyolefin compounds are extremely difficult to degrade under natural conditions and can exist in the soil for 200 to 400 years. The average residual film volume of cotton land is 4.6 kg per mu. The smallest residual diameter is about 1 cm, and the largest diameter is 30 cm, of which the diameter is between 10 cm and 20 cm, accounting for about 60%. The residual film remaining in the soil not only destroys the ecological environment of the farmland, but also forms a barrier zone, which affects the development and growth of the seed roots. According to the survey, the soil contaminated by the residual film for 3 to 5 years, the sugar beet reduced by 2% to 3%, the peanut yield decreased by 3% to 6%, and the cotton yield decreased by 10% to 23%.

At present, the implementation of mechanized recycling of residual film is undoubtedly the most effective way to solve residual film pollution, and has enormous social and ecological benefits for protecting cultivated land and achieving sustainable development of agriculture.
