Abstract: Tea garden soil which had been fertilized five years was chosen for the study, and soil microbial characteristics and enzyme activities were studied. The results showed that: Earthworm bio-organic fertilization treatment (100% FBO) could significantly increase soil microbial biomass carbon, respiration rate, microbial quotient, level of bacteria, fungi and actinomycetes in 0-20 cm soil level, and could significantly improve the activity of catalase, urease, invertase and alkaline phosphatases in soil (P<0.05). In 20-40 cm soil level, the indicators of microorganisms and enzyme activities under 100% FBO treatment were also higher than CK, but most of them did not reach significant level. Bio-organic fertilization technology could significantly increase the number and activity of soil microorganisms, and upgrading soil enzymes activity which was related to soil nutrient. This would help to restore or rebuild the damaged soil ecosystem of tea garden, and to enhance soil quality.

Key words: earthworm, fertilization bio-organic technology, soil microbial, soil enzyme, soil of tea garden
