| 摘 要： | 连续5年对蚯蚓生物有机培肥的茶园土壤微生物特征以及酶活性变化情况进行了研究,分析了蚯蚓生物有机培肥技术(FBO)对茶园土壤微生物特征及酶活性的影响。结果表明,蚯蚓生物有机培肥处理(100% FBO)可以显著增加0~20 cm土层微生物量碳、呼吸速率、微生物熵、细菌、真菌和放线菌等表征土壤微生物数量和活性的指标,并可以显著提升过氧化氢酶、脲酶、转化酶和碱性磷酸酶的活性(P0.05)。在20~40 cm土层,100%FBO处理的微生物和酶活性相关指标也高于CK,但多数未达到显著水平。蚯蚓生物有机培肥技术可以显著增加表层土壤微生物的数量和活性,并提升与土壤养分转化密切相关的几类酶的活性,有利于受损茶园土壤生态系统的恢复和重建,全面提升土壤质量。

| 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. |
