| 摘 要： | 研究了孪井灌区典型地段包气带土层可溶盐分在灌溉前后的变化,分析了灌溉水和土壤水盐分动态特征,并在室内进行了不同类型土壤的淋滤试验。结果表明引黄灌溉是使土壤脱盐的过程,尤其是灌溉初期,土壤脱盐非常明显。灌溉洗盐与包气带岩性和灌水量有关,砂壤土较黏砂土易脱盐,土壤初始含盐量越大,灌溉量越大,土壤脱盐量就越大。 |
| 关 键 词： | 灌溉 岩性 盐分动态 灌溉洗盐 |

| Abstract: | This paper systematically analyzes soluble salt before and after the irrigation for unsaturated soils in a specific sector of Luanjing irrigation area.The chemical dynamic state of irrigation water and soil solution is analyzed during the irrigation,and elution tests for different type soils are carried out in the laboratory.The results show that the irrigation is the process of soil desalination,especially in the early irrigation,desalination is very obvious.The desalination of irrigation relates to the un... |
