Abstract:: The albic soil was used as the material for the test, the mixed soil was used to screen the algae soil, and the dominant strains were fermented. The inoculation quantities of 1%, 3%, 5% of the three kinds of bacteria were set up. Under the same conditions, the treated bacteria were cultured with the cultured albic soil. The effects of bacterial cell on the transformation of water-soluble humus in albic soil were investigated. The theoretical basis for the study of microbial mechanism of soil humus transformation and soil organic fertilization was provided. The results show that: (1) all treatments show that WSS content is a trend of decreasing first and then increasing; (2) the content of organic matter in the treatment of 1% bacterial is the most gentle, decreases first and then increases, and the content of organic matter increases on the thirtieth day after adding 3% bacterial, the content of organic matter increases from thirtieth day to sixtieth day, and the content of organic matter in treated soil is always higher than that in control on one hundred and twentieth day; (3) the contents of HE in the treated soils increase significantly after adding the bacterial, and then decrease, the HE content in the treated 3% bacterial is the most obvious. the content of HA in each treatment decreases continuously, and the contents of HA in adding 1% and 3% bacterial decrease rapidly, at the end of the incubation, the FA content does not change obviously; (4) at the initial stage of culture, the number of microorganisms in the treated soils increases and then decreases, the relative content of microbial biomass carbon was higher than that of the control after adding different concentrations of bacterial, and the relative content of microbial biomass carbon of the treatment group with 1% bacterial is the highest.
