摘要

2005-2006年在云南农业大学试验农场10°坡地上研究了玉米间作蔬菜和牧草对径流、土壤侵蚀的影响。结果表明，间作的水土保持效果优于玉米单作。2005年径流和土壤侵蚀，间作比玉米单作分别减少24.4%～34.1%和13.0%～50.9%;2006年间作比玉米单作分别减少8.5%～55.3%和32.5%～85.3%。其中玉米间作牧草水土保持效果最好，其次是玉米间作马铃薯及间作甘蓝。2005年径流量与降雨量、降雨强度和降雨侵蚀力呈极显著正相关;土壤侵蚀量与降雨强度和降雨侵蚀力呈极显著正相关关系。

Abstract

An experiment was conducted on plots of 10 degree slope at the teaching and experiment farm in Yunnan Agricultural University in 2005-2006. The effect of maize intercropped with vegetables and pasture on runoff and sediment was investigated. The result show that the soil and water conservation function of maize intercropping was better than monoculture of maize. Compared with monoculture maize

the runoff and sediment of intercropped maize have been reduced by 24. 4%~ 34. 1% and 13. 0% ~ 50. 9% in 2005

8. 5%~ 55. 3% and 32. 5%~ 85. 3% in 2006

respectively. Maize intercropped with pasture had the best soil and water conservation effect

followed by maize intercropping with potatoes and cabbages. A significantly positive correlation had been identified between runoff and sediment with rainfall intensity and erodibility.
