敖汉旗1985年开始引进推广机械铺膜技术,1989年全旗机械铺膜面积就已发展到1万多亩,1990年全旗地膜玉米总面积2.6万亩,其中1.8万亩采用机械铺膜,占地膜玉米总面积的70％多。实践证明,机械铺膜效率高、成本低、质量好、省地膜、速度快。机械铺膜比人工铺膜提高工效5倍,每亩节省人工3个,节省人工费9元;机械铺膜拉得紧,压得实,膜面平整,均匀一致。因此,比人工铺膜防风性能好,抗雨水冲刷,保水增温效果好,
Aohan Qi introduced in 1985 to promote the mechanical membrane technology in 1989, the whole flag of the mechanical membrane area has been developed to 10,000 mu, 1990 full-flag maize corn a total area of 26,000 mu, of which 1.8 million mu mechanical membrane , Accounting for more than 70% of the total area of plastic film corn. Practice has proved that mechanical filming high efficiency, low cost, good quality, provincial film, fast. Mechanical film than the artificial membrane to improve work efficiency 5 times, save 3 artificial labor per acre, saving labor costs 9 yuan; mechanical film pull tight, pressed real, membrane formation, uniform. Therefore, than the wind-proof performance of good film, anti-rain erosion, water warming effect,
