摘　　要：玉米籽粒田间机械直收是我国玉米生产发展的方向,黄淮海区玉米收获时籽粒含水率偏高,并导致破碎率偏高是当前该区夏玉米田间机械粒收存在的主要问题。生产上为提高作物的机械收获质量和生产效益,常常使用化学催熟技术促进作物提前成熟,降低植株或籽粒含水率,以适应机械收获的需要。介绍几种常用的化学催熟剂及化学催熟对作物产量、品质和机械收获的影响,并对化学催熟在夏玉米上的应用进行初步探讨。The direct harvest of grain with the machinery in field is the focus for future turning way of maize production in our country,the most significant problem of maize grain mechanical harvest is the high moisture content of grain at harvest time and lead to high grain breakage rate.To improve the quality and efficiency of crop mechanical harvest,chemical ripening technology is often used to promote crop maturation,lower water content,suitable for mechanized harvest.This paper introduces several commonly used chemical ripener and chemical ripening on crop yield,quality and effect of mechanical harvest,and the application of chemical ripening in maize were discussed.
