摘要
本文研究了厩肥区、秸杆区、化肥区和无肥对照区四种不同培肥管理措施对土壤微生物生态特征的影响,结果表明,施入厩肥、化肥或秸杆还田均能明显增加土壤微生物生物量及呼吸量;土壤微生物生物质量、土壤呼吸及代谢商等微生物指标均与土壤有机质的变化呈相同的变化趋势;BIOLOG生态盘测试亦揭示了培肥管理措施能明显影响土壤微生物的群落结构。
The microbial ecology of four paddy soils with different fertilizer systems was investigated.The results showed that farm manure,inorganic fertilizer and straw manure significantly increased soil microbial biomass and basal respiration.Three microbiological parameters,namely,microbial biomass,basal respiration and metabolic quotient were closely correlated with soil organic matter.Multivariate analysis of BIOLOG data also demonstrated that fretilizer system had a significant impact on soil microbial community structure.
