摘　　要：本试验采用培垅、地膜覆盖，配方施肥、育苗双行种植等人工调控技术，促进了山区马铃薯早熟、丰产和高效．该技术投资少，操作简便，经济效益高．在转化地方资源优势为商品优势中有着广阔的前景．In this experipent,we had adjusted soil-ecology-environment system by earth up ridge, cover land with plastic film. and use prescription fertilizer, growing seedlings and double line plant for fully utilized resources. With which, we could get potato earlier ripeness with high yield. Furtherly, we also studied its benefit. The conclusions were:Those techuniques had good benefit with low input and easy to be implemented. So that would have a broad prospects to translate local resources to goods superiority.
