| 摘 要： | 本试验于2005年在达拉特旗测定了设置沙柳沙障的沙丘和对照样地(未设沙障)的土壤机械组成、有机质、全氮、全磷、全钾、酸碱度等理化指标,对比分析沙柳沙障对土壤理化性质的影响。结果表明:设置沙柳沙障的沙丘表层细沙含量比对照样地提高15.1%、粘粒提高18.3%、粉沙含量是对照地的1.8倍,说明设置沙柳沙障能够增加沙丘表层细颗粒含量,有效控制地表粗化。设置沙柳沙障后沙丘土壤有机质含量是对照地的1.78倍,全氮含量是对照地的1.97倍,全磷含量是对照地的1.64倍,全钾含量是对照地的1.14倍,说明设置沙柳沙障能够改善沙丘土壤的养分状况。 |

| Abstract: | The soil physical composition,organic matter,total nitrogen,total phosphorus, total potassium and pH of Salix psammophila ccheckerboard and contrast sand of Dalate county were investigated in 2005,the effects of Salix psammophila checkerboard on physical and chemical characteristics of sandy soil were analyzed.Study indicated that establishing Salix psammophila checkerboard can effectively keep the earth's surface from coarsening,because Salix psammophila checkerboard can obviously increase the fine sand and clay sand of soil surface,accounting for 15.1%,18.3%,powder sand increased by 1.8 times.Organic matter,total nitrogen,total phosphorus and total potassium content was higher than barren sand,increasing by 1.78,1.97,1.64,1.14 times,it showed Salix psammophila checkerboard improved fertility condition of soil. |
| Keywords: | Salix psammophila checkerboard sandy soil physical and chemical characteristics |
