为了探究微生物肥料在节肥条件下对烟草根际微生物功能多样性的影响,应用Biolog-ECO技术,研究了金农肥中肥和德根贝在0% 、10%、20%、30%节肥水平下烟草根际微生物碳代谢特征。结果表明,金农肥中肥和德根贝的根际微生物,对4类碳源的利用能力均随节肥量的增加而下降;主成分分析表明,在节肥水平下,金农肥中肥和德根贝的根际微生物对碳源的利用方式不同,金农肥中肥偏好代谢中间产物及次生代谢物,而德根贝偏好糖类、脂肪酸和脂类;金农肥中肥和德根贝的根际微生物群落的丰富度、均匀度、优势度在各节肥水平下均显著高于全量施肥(P

In order to explore the effects of microbial fertilizer on functional diversity of rhizosphere microorganisms in fertilizer-saving levels, the Biolog-ECO technology was adopted to study the effect of two microbial fertilizers (Jinnong No. 1 and Degenbei) on carbon metabolism characteristics of rhizosphere microbe functional diversity in 4 fertilizersaving levels(0%,10%,20% and 30%). The results showed that: the utilization ability of 4 carbon sources were decreased as the amount of chemical fertilizer reduction in groups treated with microbial fertilizer. The principal component analysis showe...
