农业机械不仅可以大幅度提高劳动生产率,而且可以显著提高土地产出率和资源利用率。特别是现代化的农业机械,不仅功率大、速度快,还能够同时进行几种联合作业,有利于抢农时、争积温、抗灾害、降成本,而且可以根据需要设计、制造和调节结构和功能,完成高精度的作业,做到“定时、定量、定质、定位”作业。农业机械的作用非常多,业内专家和行业专业文献都进行了详尽的叙述。但是,笔者以为,农业机械的作用总的来说只有一个,那就 Agricultural machinery can not only greatly improve labor productivity, but also significantly improve land productivity and resource utilization. In particular, modern agricultural machinery not only has the advantages of high power and high speed, but also can perform several joint operations at the same time. It is conducive to grab farming, fight accumulated temperature, resist disasters and reduce costs, and can design, manufacture and adjust structures and functions as needed. Complete high-precision operation, so that “time, quantitative, qualitative, positioning ” homework. The role of agricultural machinery is very much, the industry experts and industry professionals have carried out a detailed account of the literature. However, I believe that the role of agricultural machinery in general there is only one, then
