Abstract

Mierobal number at the root region soil under Chinese fir seedling was greatly increased after applying mineral fertilizer。Under N,PK and NPK treatments,the total microbal number was 2.29,1.41 and 2.89 times that of cheek,respectively.Bacteria number increased was the most,and then fungi.On the contrary,mineral fertilizers not had a remarkable effect on the microbal number at the nonroot region soil as a whole.Mineral fertilizers were resPonsible for the complex changes of enzymitic activities of soil.For instance,urease and sucrase were not affected by fertilizers.Under PK and NPK treatments,Protease was greatly activited.Phosphatase could be Prominently activited only applying N.Under PK,espectively NPK,however,Phosphatase was not activited but unactivited。After using mineral fertilizers,Polyphenol oxidase at the root region soil became more unactive,and every kinds of enzyme was unaetivited at the nonroot region soil in some extent.
