| 摘 要： | 本文探讨了添加稻草和选择性抑制剂下红壤旱地和淹水稻田土壤细菌和真菌数量的动态变化.结果表明,培养期间,旱地土壤中添加稻草(Str)处理细菌和真菌数量比对照(CK)分别增加271.4%～518.8%和2900%～3608%;添加稻草+放线菌酮(Str+Ac)处理土壤细菌数量比Str处理增加34.1%～81.4%;添加稻草+四环素+链霉素(Str+Sm+Tc)处理土壤细菌数量比Str处理下降14.3%～43.5%,而真菌增加17.1%～37.6%.淹水稻田土壤中,Str处理土壤细菌数量比CK增加115.3%～362.2%,而真菌数量下降5.8%～27.8%;Str+Ac处理土壤细菌和真菌数量与Str处理基本相同;Str+Sm+Tc处理土壤细菌数量比Str处理下降39.0%～76.2%.旱地土壤中添加稻草使细菌与真菌(B/F)比率显著下降,而淹水稻田土壤中添加稻草使B/F比率明显升高.阐明旱土中添加稻草后细菌和真菌均参与其分解和转化,而真菌作用占主要,淹水稻田土壤中添加稻草的分解和转化主要为细菌.土壤水分对添加稻草土壤微生物群落变化有较大影响. |
