摘　　要：针对河套灌区目前玉米生产投入高、产量水平也较高的现状，进一步挖掘增产潜力，2015年在杭锦后旗和临河区进行了玉米-穴双株高密度高产栽培试验，产量达到1120．50—1239．69口/667m3，比对照玉米宽覆膜高产示范田增产14．1％-28．2％，效益平均增加464．1元／667mz，增产增收效果十分显著。试验证明，一穴双株是河套灌区玉米-项简单易行的高产高效种植模式，极具推广价值。According to the situation of high investment and yield on corn production in irrigation area in Hetao,we conducted experiment on high density and high yield corn cultivation of one hole double plants in Linhe and Hanggin Rear Banner in 2015 to further explore yield potential. The yield was up to 1 120.50~1 239.69 kg/667m2, 14.12%~28.2% increasing in wide coated corn high yield field and the average benefit was 464.1 yuan per 667m2. The results in increasing investment and yield were obvious. In a word, the experiment investigates that one hole double plants mode was a simple and feasible method on high density and high yield corn cultivation in irrigation area in Hetao with high market value.
