| 摘 要： | 以新疆生产建设兵团125团滴灌、沟灌、漫灌的棉田土壤为研究对象,分别测定不同灌溉方式棉田土壤的比重、容重、孔隙度以及团聚体结构和机械组成等物理性状.结果表明:棉田不同灌溉方式对其土壤各种物理性状产生了不同程度的影响.比重、容重表现为漫灌＞沟灌＞滴灌,而孔隙度则反之;土壤团聚体中粒径小于0.25 mm的微团聚体占了较大比重,良好结构团聚体的含量表现为滴灌＞沟灌＞漫灌,而微团聚体则相反;土壤机械组成中砂粒的含量占了较大比重,而砾石没有,砂粒、粉粒的含量均表现为漫灌＞沟灌＞滴灌,而粘粒则表现相反. |

| Abstract: | Taking the different methods of irrigation(drip irrigation,ditch irrigation,flooding irrigation) for the cotton field soil of Regimental Farm 125,of Xinjiang Production and Construction Corps in the northern region of Xinjiang as a target,we respectively measured the proportion of soil density,porosity and the reunion of the structure and mechanical components and other physical properties with the different irrigation methods in cotton field.The results showed that the different irrigation methods in the c... |
