本研究旨在探讨土壤微生物功能多样性对有机质改良的响应以及微生物功能多样性与土壤碳有效性的关系。家庭固体废物堆肥，马和兔子的粪便和鸡粪施加两个剂量。使用相同的原状土类型（Vertic Argiudoll）作为参考。采用Biolog EcoPlate（TM）测定土壤悬浮液的平均显色率（AWCD）、丰富度（R）和Shannon-Weaver指数（H）。与未修正的地块相比，修正的掺入导致AWCD、R和H显著增加（p < 0.05）。当R和H与土壤有机碳相关时，回归函数呈线性关系（R-2分别为0.77和0.72）。主成分分析允许从控制和未受干扰的网站的治疗的分化。由于管理实践，Biolog EcoPlate检测试剂盒对短期内的变化敏感。(c)2005爱思唯尔有限公司保留所有权利。
The aim of the present work was to assess the response of microbial functional diversity to organic soil amendment and the relationship between the microbial functional diversity and soil carbon availability. Household solid waste compost, horse and rabbit manure and chicken manure were applied at two doses. The same undisturbed soil type (Vertic Argiudoll) was used as reference. Soil suspensions were applied to Biolog EcoPlate (TM) and average color development (AWCD), richness (R) and Shannon-Weaver index (H) were calculated. The amendment incorporation resulted in significant increases (p < 0.05) in AWCD, R and H compared to the unamended plots. The regression functions showed linear relationships when R and H were related to soil organic carbon (R-2 = 0.77 and 0.72, respectively). Principal component analysis allowed the differentiation of treatments from the control and the undisturbed sites. The Biolog EcoPlate assay was sensitive to changes in the short term due to management practices. (c) 2005 Elsevier Ltd. All rights reserved.
