玉米联合收割机的开发与研制在国家政策的鼓励与支持下已经开展多年了,但一直没有比较合适的机型得到大范围的使用与推广。究其根本,不仅是国家政策、地方政策等的社会性原因及收割效益方面的经济性原因,很关键的是收割机本身的技术原因导致了其使用与推广受到了限制。我们现在就玉米联合收割机的几个有关技术问题进行探讨。 (1)地区的适应性。玉米联合收割机与小麦、水稻等谷物 The development and development of corn combine harvester has been carried out for many years under the encouragement and support of the national policy. However, no suitable model has been widely used and popularized. The fundamental issue is not only the economic reason of social reasons such as state policy and local policy, but also the economic benefit of harvesting. The key reason is that the technical reasons of the harvester itself have restricted its use and promotion. We are now on the corn combine harvester several technical issues to be explored. (1) Regional adaptability. Corn combine harvester with wheat, rice and other grains
