| 摘 要： | 利用排水式蒸渗仪,通过设置6种地下水位控制处理(地下水位埋深分别为0.5、1.0、1.5、2.0、2.5 m和3.0 m)试验,探讨了太原盆地不同地下水埋深对冬小麦和春玉米生长指标、产量、产量构成因素及水分生产效率(WUE)的影响.结果表明,地下水埋深对冬小麦和春玉米千粒重的影响较小,对冬小麦干.物质重影响显著(P=0...

| Abstract: | The growth indicators,yield,yield components and water use efficiency(WUE) of winter wheat and spring maize were investigated under different groundwater depth by using drainable lysimeter.The results showed that different groundwater depth had little influence on 1000-grian weight of winter wheat and spring maize.They had significant effect(P=0.05) on dry matter weight of winter wheat.When groundwater depth was more than 1.0m,the planting density,tiller number,spike number,grains per spike of winter wheat ... |
