摘　　要：为探索坡地水土保持技术,以传统习惯种植作物为对照,开展了坡地种葛对减少水土流失技术的研究。结果表明:种植葛根可以有效地减少坡地土壤的地表径流量和土壤侵蚀量,种葛4年后地表径流量比对照减少一半以上;随着种葛年限的增加,土壤侵蚀量逐年降低。种葛第2年后,雨水对坡地土壤的侵蚀量比对照减少了58.0%,到第10年种葛处理的土壤侵蚀量比对照减少了91.1%。本研究通过对坡度在28°以内的坡地种葛,对减轻水土流失,改善土壤理化性状,培肥地力提供了一条新的有效技术途径。To explore soil and water conservation techniques on slope field,the study on reducing soil erosion by planting Kudzu was done. The traditional crop was as a control. The results showed that planting Kudzu could effectively reduce surface runoff and soil erosion on slope field. After the Kudzu was planted 4 years,the runoff was reduced to more than half. With the increasing age of planting Kudzu,the soil erosion was reduced year by year. After the Kudzu was planted2 years,soil erosion of planting Kudzu was decreased 58. 0% than the control on the slope field. After the Kudzu was planted 10 years,soil erosion of planting Kudzu was decreased 91. 1% than the control. Planting Kudzu could significantly reduce soil erosion on 28 degrees slope field and improve soil physical and chemical properties. It provides a new and effective technical approach to control soil and water loss.
