地膜覆盖栽培是提高农作物单产的一项新技术,当前已广泛应用于早稻育秧和棉花、蔬菜等经济作物的栽培,获得较高的经济效益。今年我站在乐港乡袁家村进行了彩色地膜覆盖栽培棉花试验,参试处理四个:1.绿色地膜覆盖;2.银灰色地膜覆盖;3.普通地膜覆盖;4.露地(对照)。重复两次,每小区0.05亩,播种后30天田间调查结果表现,彩色地膜处理有明显的保全苗、促早发、防蚜虫和除杂草效果:1.绿色地膜处理:全苗率79.2％、真叶4片,蚜虫危害株率7.5％,每平方尺杂草7株。2.银灰色 Film mulching cultivation is a new technology to improve crop yield, which has been widely used in the cultivation of early-rice seedlings and cotton, vegetables and other cash crops, with high economic benefits. This year I stood in Yuejiaxiang Yuanjiacun conducted a color film mulching cotton cultivation test, the participants deal with four: 1. Green plastic film cover; 2. Silver gray plastic film cover; 3. Ordinary plastic film cover; 4. Exposed (control). Repeated twice, 0.05 acres of each plot, 30 days after sowing the field survey results, the color of the membrane has obvious protection of seedlings, and promote early hair, aphids and weed control effect: 1. Green film treatment: the whole plant rate of 79.2% , True leaves 4, aphid infestation rate of 7.5%, 7 per square foot of weeds. Silver gray
