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。

Controlling soil and water loss technology on sloping field by planting Kudzu |

Abstract: | 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 planted 2 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 significant-ly 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. |
