中文摘要:
      包头市土右旗萨拉齐镇盐碱地燕麦常规翻耕与不翻耕3 cm,5 cm和7 cm播深各处理,单株干物质量和经济产量表现为:相同播深,翻耕处理>不翻耕处理;播深7 cm处理>5 cm和3 cm处理。翻耕7 cm燕麦的经济产量比对照(常规翻耕,3 cm播深)增加64.1%,与其他处理相比,也均达到极显著差异水平;不同生育时期叶片叶绿素含量、质膜透性和丙二醛含量分析表明,翻耕深播可较好地提高燕麦对盐碱的适应能力。
英文摘要:
      An experiment was cnducted to test the effect of no-tillage and conventional tillage with different planting depth on the growth of oats in saline and alkaline land in Inner Mongolia.The control group was conventional tillage with 3 cm planting depth, while two other groups with 5 cm and 7 cm planting depth.The results showed that, with the same planting depth, dry matter and yield in conventional tillage>no-tillage;in conventional tillage, 7 cm planting depth>5 cm and 3 cm planting depth.The yield of conventional tillage with 7 cm planting depth were 64.1% more than that in the control, it also appeared significant difference from other treatments.The variations of chlorophyll content and cell membrane permeability and content of MDA at different growth stages showed that deep ploughing was a high efficient measure for improving saline and alkaline land, and increasing productivity.
