摘　　要：在青铜峡邵岗镇东方红村试验基地,采用正交设计法研究了盐碱地节水灌溉对玉米各种生长发育性状及产量的影响。试验表明:覆膜情况下,玉米株高、叶面积、干物质、产量均高于未覆膜;无地下水补给时玉米的生物学特性及产量均高于有地下水补给。总体来讲,在盐碱地上玉米的各项指标以覆膜无地下水补给最佳。In this paper, influences of water-saving irrigation methods in saline-alkali land on corn development traits and yields by orthogonal design method in Dongfanghong Village, Shaogang Town, Qingtongxia City were studied. The results showed that, in the field with film, the corn height, leaf area, dry matter and yields were higher than those in the field without film. Without groundwater recharge, the biological characteristics and yields of maize were higher than those with groundwater recharge. As a whole, the maize could achieve the best indexes in saline-alkali land with films and without groundwater recharge.
