超微地膜(0.0035±0.0005mm)由运城市塑料一厂于1989年1月研制成功,同年我们在棉花生产上进行了与微膜作对比的应用试验。试验分水、旱地各两组,水地设在棉花研究所农场和临猗县,旱地设在临猗县和万荣县,随机区组排列,重复4次,同时还在大面积应用超微地膜的棉田进行了调查。试验结果表明,超微地膜和微膜同样具有增温保水,增强光合作用,优化棉田生态环境的效果,从而能促进棉花全苗早发,提高棉花产量和品质。通过对不同覆盖度的试验还证明,合理的覆盖度,应当是覆盖作用大,增产最多,效益
The ultrafine membrane (0.0035 ± 0.0005mm) was successfully developed by Yuncheng Plastic Factory in January 1989. In the same year, we conducted the application test on cotton production in comparison with the micro membrane. The experiment was divided into water and dry land in two groups. The water land was set up in the Cotton Research Institute farm and Linqu County. The dry land was set up in Linli County and Wanrong County. Random groups were arranged for 4 times. At the same time, The cotton fields were investigated. The experimental results show that the micro-membrane and the micro-membrane also have the effects of warming the water, enhancing the photosynthesis and optimizing the ecological environment of the cotton field, thereby promoting the early emergence of the whole cotton seedling and increasing the cotton yield and quality. Through the test of different coverage also proved that a reasonable coverage, should be the role of large coverage, the largest increase in production efficiency
