| 摘 要： | A pot experiment was carried out with a clay loam in a green house.The results showed that soil microbial biomass C increased with the application of organic manure at the beginning of the experiment and then gradually decreased with declining of the temperature .The soil biomass C increased at the tillering stage when the temperature gradually increased,and rose to the highest value at the anthesis stage,being about 554.9-794.4mg C kg^-1,The applicatio of organic manure resulted in the highest increase in biomass C among the fertiliztion treatments while that of ammonium sulphate gave the lowest At the harvest time the soil biomass C decreased to the presowing level. Like the soil biomass C the amount of biomass P was increased by the incorporation of organic manure and was the highest among the treatments,with the values of the check and ammonium sulphate treatments being the lowest ,Meanwhile,the changing patterns of the C/P ratio of soil microbial biomass at stages of wheat growth are also described.
