摘　　要：The research isolated phosphorus-soluble bacteria from different parts of ryegrasses and selected 7 bacteria performing better in solbilizing capacity. The test results showed that the capacity of phosphorus-solubilizing tended to be volatile in the range from 135.27 to 187.87 μg/ml and the secreting capacity of IAA was in3.47-24.27 μg/ml. It is believed that Lp59, Lp61, Lp65, Lp69, Lp70 and Lp72 are potential for further development.从多年生黑麦草根际不同部位分离具有溶磷能力的溶磷菌菌株,采用溶磷圈法筛选出7株溶磷能力较强的菌株开展溶磷潜力实验。结果表明,各菌株的磷源溶解量差异较大(135.27～187.87μg/ml),各菌株分泌IAA量为3.47～24.27μg/ml,其中以Lp59最大;综合菌株的溶磷量、分泌IAA量,认为Lp59、Lp61、Lp65、Lp69、Lp70和Lp72等6个菌株有较大的开发潜力。
