| Abstract: | By usingNFM (non-nitrogen culture medium) the rhizosphere separation to have nitrogen-fixing capacity bacteria and PKO inorganic and Mengjinna organic culture media, inorganic and organic phosphate dissolving bacteria had been isolated from rhizosphere of Lycium barbarum L. in Ningxia. The results indicated that 47 bacteria had the ability of nitrogen fixation bacteria,which screened 46 show dissolving organic and inorganic phosphate abilities.those bacteria showed strong ability of dissolving inorganic pho... |
