目前玉米覆膜技术已在各地广泛推广,玉米覆膜机的研制多种多样,从小四轮的牵引到大型拖拉机的牵引,从分段播种、覆膜到一次性完成多条垄的起垄、施肥、播种、和墒、镇压、铺膜、覆土的作业,实现了玉米覆膜的机械化。1997年友谊农场五分场为了大力推广玉米覆膜技术,进行了不同形式的覆膜机改装,现以BEW-5.4型垄作机改装成覆膜机为例。 一、该类型覆膜机的结构特点(以700mm垄距为例)
At present, the corn laminating technology has been widely popularized all over the country. There are many kinds of corn laminating machine developed from small four-wheeled tractors to traction of large tractors. From the section sowing and laminating, Fertilization, sowing, and moisture, repression, film, soil cover operation, to achieve the mechanization of corn film. 1997 Friendship Farm five-point field In order to promote corn film technology, carried out different forms of laminating machine modification, now BEW-5.4 ridge machine converted into laminating machine as an example. First, the type of laminating machine structural characteristics (to 700mm Ridge distance, for example)
