夏玉米籽粒收获机械化技术是玉米生产全程机械化技术的重要环节之一,是玉米丰产丰收的重要保证。黄淮海夏玉米产区是我国的玉米主产区,仅河南省夏玉米种植面积就达300多万hm~2(4 500多万亩)。长期以来,黄淮海区玉米的收获多采用人工或分段机械化收获模式,果穗晾晒、脱粒和籽粒晾晒等环节劳动强度大,费工又费时,已成为玉米收获的一大难题。特别是近几年来,随着土地流转步伐的加快、种植大户的增 Summer maize grain harvesting mechanization technology is one of the most important aspects of mechanization of corn production, which is an important guarantee for high yield and good yield of corn. Huanghuaihai summer maize producing areas is China’s main producing areas of corn, only the summer corn acreage in Henan Province amounted to more than 3000000 hm ~ 2 (45000000 acres). For a long time, harvesting of corn in Huang-Huai-Hai area has adopted artificial or segmented mechanized harvesting mode. The work of ear drying, threshing and drying of grain is labor-intensive, time-consuming and time-consuming, which has become a major problem for corn harvesting. Especially in recent years, with the accelerated pace of land transfer, the growth of large families
