摘要:
采用人工模拟降雨方法，以耕地和裸地为对照，对3种多年生牧草进行水土保持能力分析。结果表明：产流时间依次为裸地>耕地>三叶草>狼尾草>狗尾草，在76 mm/h雨强下径流量、1 h径流和泥沙累积量、土壤侵蚀量依次是耕地>裸地>三叶草>狼尾草>狗尾草，在53 mm/h雨强下泥沙量、1 h径流和泥沙累积量、土壤侵蚀量依次是裸地>耕地>三叶草>狼尾草>狗尾草。3种牧草均有很好的水土保持效果，其中狗尾草水土保持效果最好，三叶草相对较差。
Abstract:
A study on soil and water conservation capacity of three introduced grasses under artificial simulated rainfall was conducted in contrast to the farmland and the bareland. The results showed that three grasses have good soil and water conservation capacity. The Setaria sphacelata cv. Narok is the best. The water movement times are successively bareland > farmland > Trifolium repens cv. Haifa > Pennisetum clandestinum cv. Whittet > Setaria sphacelata cv. Narok. The runoff and sediment accumulant as well as soil erosion under 76 mm/h artificial simulated rainfall are successively farmland > bareland > Trifolium repens cv. Haifa > Pennisetum clandestinum cv. Whittet > Setaria sphacelata cv. Narok. The runoff and sediment accumulant as well as soil erosion under 53 mm/h artificial simulated rainfall are successively bareland > farmland > Trifolium repens cv. Haifa > Pennisetum clandestinum cv. Whittet > Setaria sphacelata cv. Narok.
