地膜覆盖栽培棉花是一项增产幅度大、经济效益高的新技术。我县八三年在石脑公社望城大队罗下生产队试验示范,试验面积14亩,共收皮棉2940斤,亩产210斤,比不覆盖的棉田亩产170斤亩增40斤,增长26.6%。通过一年来的试验、示范,一致认为地膜覆盖是棉花栽培史上的一项重大改革,是大幅度提高单产的新途径。历年来我县由于春季多雨低温和自然灾害等因素的影响,往往难以达到“三早”夺高产目的。为了摸索棉花高产途径,现将近几年来增产效果显著的地膜植棉的试验示范情况简报如下。地膜覆盖的优越性一、增温保湿。太阳光线透过薄膜晒到土壤,由于地膜
Film mulching cultivation of cotton is a large increase rate, high economic efficiency of new technologies. Eight or three years in our county Shicheng commune Wangcheng Brigade Luo production team test demonstration, test area of 14 acres, received a total of 2940 kg of lint, mu yield 210 kg, than the uncovered cotton mu of 170 kg mu by 40 pounds, an increase of 26.6 %. After a year of experiments and demonstrations, it was agreed that plastic film mulching was a major reform in the history of cotton cultivation and a new way to substantially increase yields. Over the years, due to the rainy spring in our county and natural disasters and other factors, it is often difficult to achieve “three early” high-yielding projects. In order to explore the high-yielding ways of cotton, now in recent years a significant yield increase effect of plastic film mulching demonstration briefing is as follows. The advantages of a plastic film, warming moisturizing. The sun shines through the film to the soil due to the film
