The introduction of the plastic film mulching cultivation technology since 1978 in China has now developed into the world with the largest plastic film mulching cultivation area, which exceeds 3 hundred million acres. For a long time, polyethylene ultrathin mulching films with the thickness of about 0.01mm are mainly used in China, are not easy to recover, are extremely difficult to degrade under natural conditions (the degradation period is 200-400 years), and accumulate year by year to form white pollution, so that a series of problems of soil structure damage, farmland quality reduction, crop yield reduction, blocked farm work operation, secondary environmental pollution and the like are caused.
Xinjiang is the area where the plastic film mulching cultivation technology is used in the field at the earliest time in China, residual film pollution becomes an important factor influencing the ecological environment and the sustainable and healthy development of the Xinjiang farmland, and serious harm is caused to the development of Xinjiang characteristic agriculture and regional economy. Research and research results show that the average residual quantity of mulching films in the field of cotton of the military groups produced and constructed in Xinjiang is 17.4 kg/mu, the average yield reduction of seed cotton is 11.5 percent, and the quality of cotton and textiles is also influenced after residual mulching films are mixed into the cotton. At present, the mulching area of the plastic film in the whole area of Xinjiang exceeds 5000 ten thousand mu, the average mu dosage exceeds 4.0kg, the recovery rate is less than 40 percent, more than 10 ten thousand tons of residual plastic film are newly added every year, and an effective treatment technology is urgently needed.
Since 1982, agricultural and mechanical researchers in China have already conducted research on related technologies. According to incomplete statistics, the machine types developed up to now can be more than 100, and can be divided into a seedling-stage residual film recycling machine, a post-autumn residual film recycling machine and a pre-sowing residual film recycling machine according to the operation period, and can be divided into a surface-layer residual film recycling machine, a shallow-ploughing-layer residual film recycling machine and a ploughing-layer residual film recycling machine according to the operation depth. However, the actual production site is complex, the straw, soil, stone, residual film and the like are mixed, and the mulching film is fragile and easy to wind, so that the recovery technology is difficult, and the related mechanization technology has obvious defects and cannot well meet the agricultural production requirements. For example, patent CN201620687696.4, without a film collecting box, needs to stop and unload the film by 30-50 meters; for example, patent CN201820262175.3, although there is a film collecting box, it can not process straw effectively, the residual film is in fluffy state, and the film box is easy to fill. Therefore, the film is frequently unloaded, and the effective and continuous operation is difficult to complete, which not only affects the operation efficiency, but also brings inconvenience to the secondary cleaning work because a large amount of film piles are piled in the field after the operation.
