摘　　要：有机农业提倡与自然共存不破坏平衡,而自然界的土壤中存在许多可促进植物生长的植物根圈微生物(plant growth promoting rhizobacteria,PGPR),此类微生物可分泌促进植物生长的物质,并可诱导植物产生抗性基因,增强植物抗病.PGPR可产生有机物质促进植物生长,改善土壤肥力,增加可溶性磷及铁,诱发植物抗病、克服逆境、增强营养吸收,固氮或防治病害等,在有机农业上有助于植物增产,改善农业对化学肥料的依赖,生产出健康的作物.参25.Organic agriculture advocates coexistence and balance with nature. There are a lot of plant growth promoting rhizobacteria （PGPR） in the soil, which can promote plant growth and induce plants to produce resistant gene that could improve the disease resistance. PGPR produce organic matters that have many benefits, such as promoting plant growth, improving soil fertility, increasing soluble phosphorus and Fe, strengthening the plant disease resistance, overcoming adversity, enhancing nutrient absorption for plants,fixing nitrogen, controlling disease, and so on. On the aspect of organic agriculture, PGPR help plants to increase production, reduce agriculture＇s reliance on chemical fertilizer, and produce healthy crops. 25refs.
