利用BIOLOG研究长期施肥后茶园土壤微生物群落功能多样性变化,结果表明:与清耕(CK)相比,各长期施肥处理AWCD值的变化速度(斜率)和最终能达到的AWCD值均有不同程度提高,其大小顺序为:DWY＞DY＞W＞CK,可见施肥能不同程度提高微生物整体活性和丰富度,以有机无机肥配施效果最好.分析多样性指数表明:各处理对土壤常见微生物种类影响并不大,施有机肥使微生物群落均匀度有所降低.对碳源利用主成分起分异作用的主要是糖类和羧酸类物质.对AWCD值、多样性指数与土壤养分因子的相关性分析表明,在红壤茶园中土壤肥力提高有利于土壤微生物活性的提高.

The effects of long-term fertilization on soil microbial communities of tea plantation were investigated by using BIOLOG techniques. Based on AWCD and community diversity index, the treatments with fertilizers resulted in increasing the abundance and diversity of soil microorganisms compared to the non-fertilizing treatment, the combination of inorganic and organic fertilizers showed the greatest effect followed by the application of organic matter while inorganic fertilizer had less effect. Long-term fertilization exhibited little influence on the common species of soil microorganisms accordi...
