在青岛全国展会上,笔者发现了一个有趣的现象:几乎所有玉米机生产厂家都展示了玉米籽粒直收的产品。然而,这种产品在大型农场作业中还并不常见,更谈不上普及,缘何会得到厂家如此地关注?通过一些采访,笔者获悉,用户对这种产品已经有了殷切期盼。当前,我国玉米机械化收获方式主要是以摘穗剥皮为主。然而剥皮收获后,玉米还需要“晾晒、脱粒再晾晒”等步骤,尤其是晾晒,受地方局限大,同时也会造成一定损失。这种情况下,还是不利于规模化生产,占用了劳动力,增加了成本。在农村劳动力越来越少,越来越贵的情况下,农民对籽粒直收已经有了迫切需求。从收获机械层面来说,发达国家的农机发 At the Qingdao National Exhibition, I found an interesting phenomenon: almost all corn machine manufacturers have demonstrated direct harvest of corn grain products. However, this product is not uncommon in large-scale farm operations, not to mention the popularity of why manufacturers will be so concerned about? Through some interviews, I was informed that the user has this product has been eagerly looking forward to. At present, the harvesting method of maize mechanization in our country is mainly based on pickling and skinning. However, peeled and harvested, corn also need “drying, threshing and drying ” and other steps, especially drying, subject to local limitations, but also cause some losses. In this case, it is still not conducive to large-scale production, occupy the workforce, increasing costs. With less and less labor in the rural areas and more and more expensive peasants, there has been an urgent need for direct grain collection. From the harvest machinery level, the developed countries, the development of agricultural machinery
