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一穴双株高密度高产栽培试验,产量达到1 120.50~1 239.69㎏/667m2,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/667m2,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一项简单易行的高产高效种植模式,极具推广价值。 In view of the current situation of high input and high yield of corn production in Hetao Irrigation District, the potential for increasing production was further tapped. In 2015, two high-density and high-yield cultivation experiments of corn in one hole were carried out in Hangjinhou Banner and Linhe District. The yield reached 120.50-1 239.69㎏ / 667m2, which is 14.1% -28.2% higher than that of the control corn high-yield high-yielding demonstration plots. The average increase of benefit is 464.1 yuan / 667m2, and the effect of increasing yield and income is very significant. Tests show that one hole Shuang Zhu is a simple and feasible Hetao Irrigation high-yield and efficient planting mode, very promotional value.
