地膜栽培技术引入我国以后,引起了广泛重视,对瓜菜以及其它作物都有增产效果。我所在1980年对棉花进行小面积试验,试验地为3.2亩,采用国产0.015毫米透明聚乙烯薄膜覆盖,设四个处理即: (1)60厘米等行距单行小垅覆盖。4月16日抢墒起垅盖膜,4月24日人工开孔播种,穴距20厘米,每穴留苗2株,每亩11000株,面积为0.315亩。
After the film cultivation technology was introduced into our country, it attracted a great deal of attention and had the effect of increasing yield on vegetables and other crops. In 1980, I experimented on a small area of cotton with a test area of 3.2 mu. It was covered with a domestically made 0.015 mm transparent polyethylene film. Four treatments were: (1) covering a row of 60 cm with a single row of small loops. On April 16th, it razed and covered the membrane. On April 24, artificial opening was sown. The hole distance was 20 cm. There were 2 strains of Liao Miao per hole, with 11000 plants per mu and an area of 0.315 mu.
