据统计,近年来我国玉米种植面积年均增加2%,2010年全国玉米种植面积为3000万公顷左右,是仅次于水稻(3300万公顷)的第二大农作物。我国玉米种植面积的稳步增长,2007～2008年国际原油价格暴涨,以及生物乙醇的巨大市场需求引发了全国玉米种植的热潮,使得玉米田除草剂成为国内外农药生产企业争相开发与生产的热点品种。 According to statistics, in recent years, China’s corn acreage has increased by 2% annually on average. In 2010, the corn acreage in China was about 30 million hectares, the second largest crop after rice (33 million hectares). The steady growth of corn acreage in China, the soaring international crude oil prices from 2007 to 2008, and the huge market demand for bioethanol have led to the upsurge of corn planting in China, making the herbicide of corn field a hot spot competing for the development and production of pesticide manufacturers both at home and abroad.
