(2006年8月5日)近年来,小麦收获机械化问题基本解决以后,农机部门重点研究了北方地区保护性耕作问题和南方地区水稻机械化问题。可以说在这两个问题上,我们已经有了一个比较清晰的思路,从技术上、推广方法上、工作措施上研究得比较透彻,然而,对玉米收获机械化问题有必要深入探 (August 5, 2006) In recent years, mechanization of wheat harvest basically solved later, the agricultural machinery department focused on conservation tillage in the northern region and the mechanization of rice in the south.

However, it is necessary to probe deeply into the mechanization of harvesting corn
