在露地栽培条件下，研究了配施AM或农大哥生物菌肥及化肥减量对胡萝卜、花椰菜、西芹、莴笋主要性状及产量品质的影响。结果表明，在常规施肥水平下，化肥减量20%并配施AM或农大哥生物菌肥，可提高胡萝卜、花椰菜产量，改善品质；化肥减量10%并配施AM或农大哥生物菌肥，可显著提高西芹、莴笋单重及产量，降低硝酸盐和粗纤维含量。表明在合理配施生物菌肥的条件下，胡萝卜、花椰菜栽培化肥施用量可降低20%，西芹、莴笋栽培，化肥施用量可降低10％。

A field experiment was conducted to investigate the effects of combined application of bacterial manure and chemical fertilizer reduced on quality and yield profit of plateau-grown summer vegetables (carrot， cauliflower， celery， asparagus lettuce) in Hexi corridor high-altitude cold area. The results showed that the yield and quality of carrot and cauliflower were promoted significantly by applying Nongdage or AM bacterial manure under chemical fertilizer was reduced 20% . Moreover yield and profit were increased significantly by applying bacterial manure under chemical fertilizer was reduced 10% on celery and Asparagus lettuce. This experiment result have already prove is viable in produce practice of carrot and cauliflower that fertilizer reduce lower 20%， fertilizer reduce lower 10% on carrot and cauliflower compares with current level under the condition of combined application of bacterial manure reasonable .
