The design of the film laying machine has the advantages of simple structure, small volume, low cost, high efficiency, convenient use, strong practicability, convenient disassembly and transportation, basically can satisfy the requirements of current various film. Use of diesel traction, can be a fast and efficient completion of ditching, exhibition of film, film, film, covering the operation, can ensure the film quality.Key words:Film;Agricultural plastic film laying machine;Ditching plow;1 前言 现今在我国很多地区，一些反季作物蔬菜等冬季保温种植广泛推广的一项技术是在耕整后的地面使用塑料薄膜覆盖。耕整后采纳地膜覆盖有提高土壤温度，减少土壤水分蒸发，防止杂草生长等好处。地膜通常是黑色 PE 薄膜或透明，也有绿，银色薄膜，用于地面覆盖，以维持土壤结构，防止害虫侵袭作物和某些微生物引起的病害等，促进植物生长的功能。当前，常用的铺膜机结构复杂，体积大，成本较高，假如用人工铺膜又会造成进度太慢，费工，劳动强度大，人力成本高。这种情况的出现，就需要寻找一种低投资高效率易于普及的铺膜设备。我国在 20 世纪 70 年代末才开始推广应用农用地膜,历史不长却进展很快。如今,利用农用地膜进行促成栽培已成为农业生产中一项重要的栽培技术,收到了很好的社会和经济效益。可以肯定,随着"一优二高"农业的不...
