为进一步加快我市现代农业建设,提升农业产业发展水平,黄骅市农业局从东北地区学习并引进了玉米宽窄行机械化种植技术,即大垄双行玉米种植技术,并选定齐家务乡二科牛村为示范园区。2015年园区共播种夏玉米1000亩。其中4000—4500株/亩、4500—5000株/亩大垄双行播种共700亩,常规等行距播种300亩。玉米宽窄行种植模式营造了通风透光的生长环境,形成了垄垄是边行的边际效应;辅之以适当增加密度
In order to further speed up the construction of modern agriculture in our city and enhance the development level of agricultural industry, Huanghua Bureau of Agriculture learned and introduced mechanized planting technology of corn wide and narrow lines from northeast China, that is, Niu Cun as a demonstration zone. In 2015, the park sowed a total of 1,000 mu of summer corn. Among them, 4000-4500 plants / mu, 4500-5000 plants / mu are planted with a total of 700 mu of large-ridge double-row sowing lines and 300 mu of conventional sowing lines. Corn wide and narrow row planting mode to create a ventilation and light of the growth environment, the formation of ridge ridge is the marginal effect of the line; supplemented by the appropriate increase in density
