Traditional mulch film is a film blown from polyethylene. It is the result of the development of the plastic industry. The earliest mulch film was researched by British and Japanese scientists in the 1950s and used in agriculture.
A thin layer of mulch film has very powerful functions, especially for warming, moisture preservation, weed control, and salt pressing, etc., which greatly changed the growth environment of crops and changed the agricultural planting mode. Areas cannot be planted, or crops that are not highly effective can grow well.
The use of mulch film is not all benefits. While increasing production and efficiency, and ensuring the production of food, vegetables, and cash crops, the side effects of large-scale use of mulch film begin to appear. This is mulch film pollution.
Biodegradable mulch film is one of the effective measures and means to replace traditional mulch film and solve the residual pollution of mulch film. Existing test results show that biodegradable mulch film has shown good effects in potato, peanut, tobacco and rice production.
in the long run, with the improvement and improvement of technology, the partial replacement of traditional mulch with biodegradable mulch is one of the important measures to solve the residual pollution of mulch.
