摘要
作为缓解引黄灌区泥沙淤积问题的一种解决方案,引泥沙入田值得作更深入的研究。分析了灌水定额对土壤颗粒级配的影响以及在传统灌溉和波涌灌溉2种灌溉处理下,引黄泥沙在田间的运移规律。结果表明,浑水灌溉可以提高土壤中沙粒、黏粒含量,降低粉粒含量,改善土壤结构性,并且灌水定额越大,变化越大。波涌灌溉可使入田泥沙运移更加均匀,有利于整体改善土壤结构。
As a scheme relieving the issue of sediment deposition in the Yellow River Irrigation Area, it is worth while doing a further research introducing the sediment into the field. This study analyzes the impact of irrigation quota on soil particle composition and the motion law of the sediment introduced into the field under two kinds of irrigation treatments： the traditional irrigation and the surge irrigation. The results show that muddy irrigation may increase the soil content of sand and clay and reduce the silt content, and im- prove the soil structure as well. The greater the irrigation quota, the greater the change. Surge irrigation makes the migration of the sediment introduced into the field more uniform and integral improve soil structure.
