摘要： The Alley cropping technology is special technology of the agro-forest system. Since 80's long-term international cooperation on sloping land, conducted in Asia and Africa, showed good results on soil erosion and runoff control, which provided an alternative technology and system for management for sustainable agriculture. Under the support of Swiss Agency of Development and Cooperation, the International Water Management Institute nine-years data were collected from the long-term soil conservation experiment site since 1992, locates in Bianyang township of Luodian county of Guizhou province. The results showed alley cropping technology had significant impact on soil and water conservation. The average annual quantity of soil erosion declined from 43.2 t/hm~2 in traditional farming to 4 t/hm~2 in this technology on sloping land, and capacity of water holding increased 360 m~3/hm~2 yr. By the significant control of soil erosion and runoff farmers were encouraged to increasing input that coursed to maintain or increase soil fertility. Crop yield and farmers income also increased gradually. The experiment also showed that the slope gradient decreased 1.1° per year and earth ladder of 17.1cm—20.0cm high formatted along the hedgerows per year in average to gradually form terracing land with high and stable yield. This technology had the advances on saving time, saving money, saving manpower, and easy to be implemented and managed, so it is suitable to be extended in proper mountainous and hilly areas.
