| 摘 要： | 在干旱条件下,选择农大108和郑单958为供试品种,研究其在不同种植密度下的群体产量、产量构成因素及水分利用效率的差异。结果表明,相同密度下,郑单958产量高于农大108;农大108在低密度下,穗粒数占有优势;在高密度下,郑单958在穗粒数和百粒质量上占优势;在水分利用效率方面,不同种植密度下郑单958均高于农大108。

| Abstract: | With Nongda 108 and Zhendan 958 as maize varieties, it studied the effect of two varieties and plant-densities to yield and WUE of maize in dryland; the resuhs showed that under the same density, Zhendan 958 ＇s yield was higher than Nongda 108, and under low density, the grain number per spike of Nongda 108 was bigger than Zhendan 958, and under high density, the grain number per spike and hundred grain weight of Zhendan 958 were better than Nongda 108. |
