摘要:
在测定土壤理化性质的基础上,应用Biolog-ECO技术,分析杉木1代(FCF)、连栽2代(SCF)、连栽3代(TCF)人工林和楠木人工林(PBP,对照)4种林分类型土壤微生物群落总碳源利用动力学特性、微生物多样性指数及多样性指数与土壤理化性质的相关关系. 结果显示:4种林分类型的土壤微生物丰富度(Shannon指数)、优势度(Simpson指数)、均匀度(McIntosh指数)均达到了显著差异(P < 0.05);PBP土壤微生物总体活性(AWCD)、Shannon指数、Simpson指数及McIntosh指数值均高于其他3种类型;土壤微生物生物量碳(C)含量、氮(N)含量、Shannon指数、Simpson指数与AWCD值的相关性达到了显著水平(P < 0.05);其中AWCD值、土壤pH、全C、全N、土壤微生物生物量C、N的大小顺序为PBP > FCF > SCF > TCF. 本研究表明,随着杉木连栽代数的增加,土壤微生物群落总体活性逐代下降.

Abstract:
This study used Biolog-ECO technology to investigate the change of soil microbial community. The soil microbial community functional diversity indexes, kinetics of total carbon source utilization and physical-chemical properties were analyzed in successive rotation plantations of Chinese fir (FCF, SCF and TCF) and Phoeba bournei plantation (PBP, CK) based on physical-chemical properties of the soil. The results showed a significant difference (P < 0.05) among the 4 forest stands in soil microbial richness (Shannon index), dominance (Simpson index), and uniformity (McIntosh index); the soil microorganism overall activity (AWCD), Shannon index, Simpson index, McIntosh index values were all higher in the Phoeba bournei plantation than the other three forest types. The AWCD value was significantly correlated (P < 0.05) to soil microbial biomass C, N, Shannon index, and Simpson index. The order of the AWCD value, soil pH, total C, N, soil microbial biomass C and N was as PBP > FCF > SCF > TCF. The overall activity of soil microbial community declined with the increasing continuous plantations of Chinese fir.
