夏玉米是我县秋季的主要粮食作物，年种植面积均约抓余万亩。由于从种到收长期都是采用传统的人工操作方式，又加上夏季旱灾频重，水利条件差，产量总是低而不稳。1992年以来，我县从采用适宜的机械化技术人毛并和农艺相结合，进行夏玉米机械化高产技术研究，在赵河、券桥等5个 Summer corn is my county’s main grain crops in autumn, the annual planting area about about 10000 mu. Because from the species to the long term are using traditional manual methods, coupled with frequent summer droughts, poor water conditions, the output is always low and unstable. Since 1992, my county from the appropriate use of mechanized technology, human hair and agronomical combination of summer maize mechanized high-yielding technology research in Zhaohe, Bond Bridge, etc. 5
