自80年代初起,我国地膜栽培面积不断扩大,但连年覆膜不加回收,土地耕作层残膜越积越多,给播种、中耕带来困难,影响作物正常出苗生长,使产量下降。为此,新疆农垦科学院与新疆生产建设兵团农七师55团农机厂合作,最近研制成功了“4FSZ地膜回收机”,用于检拾残留于田间的地膜,收到良好效果。经农机及质检部门进行性能测定及千余亩田间试验结果,地膜收净率平均达80％。该机主要部件有甩刀、搅龙、圆片
Since the early 1980s, the area of plastic film cultivation in our country has been continuously expanding. However, the film is not recycled in successive years. The accumulated residual film in the cultivated land is more and more piled up, which makes it difficult for sowing and cultivating crops to affect the normal emergence and growth of crops and reduce the output. To this end, Xinjiang Academy of Land Reclamation Xinjiang Production and Construction Corps Nongqijun 55 Group Agricultural Machinery Factory, the recent successful development of the “4FSZ plastic film recycling machine” for the pick up the residue in the field of plastic film, received good results. The farm machinery and quality inspection departments for performance measurement and more than a thousand acres of field test results, mulching net average rate of 80%. The main components of the machine rejection knife, auger, wafer
