| Abstract: | Four strains which could degrade phosphorus were isolated from rhizosphere of fruit trees in northern Shaanxi by PKO medium and their abilities in degrading phosphorus and promoting the growth of plants were studied.These strains could produce organophosphorus,NH3 and HCN,and could promote the growth of plants effectively.These results laid a basis for the development and production of bacterialmanure for fruit trees in northern Shaanxi. |
