Background

The plastic film mulching is one of the important factors for increasing the corn planting area and yield continuously, before the plastic film technology is used, the corn cannot be popularized and planted in a large area in dry farming areas in the northwest and the northeast of China due to the restriction of conditions such as low accumulated temperature, lack of water resources and the like, and the plastic film technology appears, so that the problems are overcome, the field operation procedure for planting the corn is reduced, the corn keeps a higher yield level, and the enthusiasm of farmers for planting the corn is improved. According to the estimation, 667 ten thousand hm2-800 ten thousand hm2 corns in the country in 2012 adopt a plastic film mulching technology, and account for more than 1/4 of the sowing area of the corns in the country.

However, with the popularization and application of mulching films, the problem of mulching film residue is increasingly prominent, and investigation shows that the residual quantity of the mulching films in the long-term mulching film farmland is 71.9kg/hm-259.1kg/hm, the residual film quantity in soil of the northwest farmland is far higher than that of the northwest China and the southwest China from the aspect of area, the harm of the residual films is mainly shown in the aspects of hindering the permeation of soil capillary water and natural water, affecting the soil hygroscopicity, reducing the soil permeability, affecting the activity of soil microorganisms, soil fertility and the like, in addition, the residual films of the soil can cause slow seedling emergence of crops, reducing the seedling emergence rate, even reducing the quality of agricultural products, causing serious pollution to the agricultural ecological environment due to the residual films, and the reasonable use of the mulching films and the enhancement of the multistage recycling of the mulching films are important contents of the future mulching films in the healthy application of the agricultural field.
