农田覆盖塑料薄膜是一种方法简单的作物栽培新技术,地面覆盖塑料后可延长作物的生长时间,提高复种指数。它还能防寒、抗旱、抗涝、增温,有利于保水、保肥、防病虫害,促苗早出,从而获得增产。目前我国还是采用人工铺膜,费工、费时,劳动强度大,效率低,很难在大面积上推广应用。山西省农科院棉花研究所从1980年开始研制地膜覆盖机。经田间试验,效果较好。1981年通过运城地区科委、省农机所、省农机鉴定站等单位鉴定,现已投入批量生产。根据样机现场播种、铺膜及测试,鉴定认为: 1.2GM-2型地膜覆盖机解决了本省棉田大面积铺
Plastic film covered farmland is a simple method of crop cultivation of new technologies, plastic covering the ground can extend the growth time of the crop and improve the multiple cropping index. It is also cold, drought, waterlogging, warming, is conducive to water conservation, fertilizer, pest control, promote seedling early out, so as to increase production. At present, our country is still using artificial film, labor, time-consuming, labor-intensive, low efficiency, it is difficult to promote the use of large areas. Shanxi Academy of Agricultural Sciences Institute of cotton from 1980 started the development of plastic film covering machine. After the field test, the effect is better. In 1981 through the Yuncheng District Science and Technology Commission, Provincial Agricultural Machinery, Provincial Agricultural Machinery Identification Station and other units identified, is now put into mass production. Sowing according to the prototype site, filming and testing, appraisal that: 1.2GM-2-type film mulching machine to solve the large area of cotton shop in the province
