Background
Mulching film is one of the important agricultural production material data. The plastic film mulching has the functions of warming, preserving soil moisture, preventing diseases, resisting insects, inhibiting weeds and the like, can increase the yield of grain crops by 20-35%, increase the yield of commercial crops by 20-60%, and makes a great contribution to guaranteeing the safe supply of Chinese grains and commercial crops. China has become the country with the largest consumption of mulching films, the largest coverage area and the largest variety of covered crops in the world. In recent years, the coverage area of the plastic film has been expanding, and the input amount has been increasing. In 2014, the coverage area of the plastic film is approximately 3 hundred million mu, the input amount of the plastic film is more than 144 ten thousand tons, and the plastic film is increased by 5.85% compared with 2013.
The existing mulching mode is to spread or roll two sides of the mulching film on the ground by manual work or wheels of a mulching machine, then compact the two sides of the mulching film by soil, and the compacted parts of the two sides of the mulching film and the ground are similar in parallel. The problem that this kind of mode exists is, the part that the plastic film got into soil is more, uses the back at the plastic film for a period, and the plastic film of both sides can often harden, entangle together with earth, tear the plastic film easily when retrieving, can't carry out the complete effective recovery of plastic film to the part that can retrieve also can remain a large amount of earth, brings the difficulty for the reuse of incomplete membrane. This is also one of the important causes of the growing severity of "white pollution" due to the large amount of mulch film remaining.
