近年来,地膜植棉发展很快,地膜用量日益增多,地膜类型亦较多.地膜植棉究竟使用哪种类型地膜好?我们于1985年在铁克其乡进行了不同类型地膜植棉对比试验.供试地膜为幅宽70厘米的普通膜(0.015毫米聚乙烯)、低压膜(0.008毫米聚乙烯线型膜)和光化膜(0.015毫米).试验分两个点,一个点设在铁克其三队,供试品种为巴州6017,面积2亩,机械铺膜并播种;另一个点设在海力排一队,供试品种为军棉1号,面积1.5亩,人工铺膜并播种.两试验点均于4月25日播种,5月上旬出苗,7月20日打顶,8月25日开始收花.
In recent years, the rapid development of plastic film mulching, increasing the amount of mulching, film types are also more.What kind of plastic film mulching is good? We conducted in 1985 in the Te Ke Township of different types of plastic film cotton contrast test The test film for the 70 cm width ordinary film (0.015 mm polyethylene), low pressure film (0.008 mm polyethylene linear film) and the photochemical film (0.015 mm) .The test is divided into two points, one point in the grams The third team, the test varieties for Bazhou 6017, an area of 2 acres, mechanical membrane and sowing; another point in the sea power row of a team for the test varieties Junmian 1, an area of 1.5 acres, artificial membrane and The two test sites were sown on April 25, germination in early May, topped on July 20, and the flowering started on August 25.
