【摘要】 随着小麦、水稻机械化收获的全面推广，玉米机械化收获也逐渐进入农田。玉米从穗收到粒收机械化，可以节约人力成本，减少霉变，增加农民收益，在保障粮食质量安全、提高玉米市场竞争力方面具有重要的意义。但比起小麦和水稻，玉米机收范围还比较小，接受度也比较低，机收率仍有待提高。为了推进玉米籽粒收获机械化，分析了黄淮海玉米籽粒直收的制约因素，以期寻找合适的解决方法，推进玉米籽粒直收的发展，提高我国玉米机械化耕作水平。更多还原

【Abstract】 With the comprehensive promotion of wheat and rice harvest mechanization,maize harvest mechanization has gradually entered farmland. Maize direct harvest from ear to kernel will save labor costs,reduce mildew and increase farmers’ benefit,which has important significance in ensuring grain quality and safety,and improving the market competitiveness of maize. However,compared with rice and wheat,the mechanized harvest range of maize is still relatively smaller,and the acceptability of maize mechanized harvest is still lower,and the mechanized harvest rate of maize still needs to be improved. In order to promote the development of maize direct harvest,this paper discussed and analyzed the restricting factors of maize direct harvest in Huang-Huai-Hai region,to find the appropriate solutions to promote the development of direct kernel harvest and improve the level of maize mechanization harvest in China.更多还原
