摘要:
为定量研究优良牧草纳罗克非洲狗尾草带的水土保持效应,于2001～2002年在云南昆明进行了研究.试验设纳罗克非洲狗尾草草带(A)、迈洛克高羊茅草带(B)和无草带种植(C)三个处理,坡度在1.2～14°之间;每个处理上部等高种植9m×2m玉米,基部种植0.5m宽的草带,底部设径流收集池.结果表明,三个处理的水土流失量为C>B>A,与对照C相比,处理A的年均径流量、侵蚀量分别减少75.9%、96.4%,处理B分别减少59.2%、88.2%;与B处理相比,处理A减少了40.9%、69.2%,说明结合农作物种植纳罗克非洲狗尾草草带,是一种很好的防治水土流失方法,在云南及南方地区的坡耕地上有着广泛的应用前景.
Abstract:
In order to quantitatively study the effect of african green bristlegrass Narok on water and soil conservation,the study was made in Kunming Yunnan in 2001 and 2002.The treatments were grass strips of African green bristlegrass Narok(A),grass strips of tall fescue Melike(B),without grass strip(C),with three replications which had slopes ranging from 13.2% to 14%,were investigated.In experiments,contour planting maize was on the top of plots and grass strips of 0.5 m wide were on the bottom of plots.The results showed that:the total quantity of runoff and soil loss of three treatments were ABC.The treatments of A averaged 75.9% less runoff and 96.4% less soil loss,and B averaged 59.2% less runoff and 88.2% less soil loss,respectively than from C.The A averaged 40.9% less runoff and 69.2% less soil loss than from B.Contour planting grass strips of African green bristlegrass Narok in sloping fields is an effective conservation measure,so it can be widely used for soil and water conservation purpose in Yunnan and southern part of the country.
