不同垄向对玉米增产效果的研究

Research on Effect of Different Direction of Ridge in Increasing Yield of Maize

以不同垄向为切入点,玉米品种龙单51为试材,于2010年开展了不同垄向对玉米增产效果的研究。结果表明:玉米在苗期、拔节期、大喇叭口期、抽雄期、灌浆期,南北垄向的各层土壤温度、叶面积系数、干物重等构成产量因子均高于其它处理,南北垄向、东西垄向、东北西南垄向分别比东南西北垄向增产7.90%、4.80%、2.83%,南北垄向值得推广。

Taking maize variety of Longdan 51 as experimental material,different direction of ridge as point cut,the effect of different direction of ridge on increasing maize yield was studied in 2010.The results showed that inseedling stage,jointing stage,huge bellbottom period,tasseling and filling stage,the yield constitutes factors such as soil temperature,leaf area coefficient,dry matter weight and so on in south-to-north ridge were all higher than those of the other treatment.South-to-north,east-to-west,and northeast-to-southwest ridge increased yield by 7.9%,4.8% and 2.83%,respectively compared with southeast-to-northwest ridge.It was worthy popularizing for planting maize with south-to-north ridge.
