Effects of wild pueraria and bahia grass on soil and water conservation and soil amelioration in red soil of hilly land

摘要: 试验研究红壤坡地野葛水土保持和土壤改良效应结果表明，横峰野葛和百喜草可有效增大土壤持水量、土壤孔隙度和降低土壤容重，提高土壤pH值、有机质和N、P、K含量，减少土壤侵蚀量和径流量，水土保持和改良土壤效果明显，且野葛综合效果优于百喜草。

Abstract: The effects of wild pueraria and bahia grass on soil and water conservation and soil amelioration were studied in red soil of hilly land.The results show that Hengfeng wild pueraria and bahia grass can improve the soil capacity of water，soil porosity，pH value，organic matter，the contents of N，P and K，and decrease the soil bulk density，soil erosion and runoff.It gets good effects in soil and water conservation and soil amelioration，and wild pueraria has better integrative effect than bahia grass.
