EFFECT OF INOCULATED AM FUNGI ON MICROORGANISM AND PHOSPHORUS CONCENTRATION IN RHIZOSPHERE SOIL

The effects of inoculated different AM fungi on microorganism population and phosphorus concentration in the rhizosphere soil.A three-compartment was used to study white clover and alfafa growth.The infection rate of mixture two mycorrihzal fungus were more than that of single-inoculated treatment obviously.The result indicated that the biomass of plants and the microorganism population were significantly increased by inoculated with AM fungi.The different of plant bimass among inoculated AM were not clear.Bacteria and actinomycete populations were increased inoculated AM fungi,the fungal populations were changed only a little.The phosphorus concentration in mycor-rhizosphere soil were lower than those of non-mycorrhizas evidently.
