| 摘 要： | 为探究施用高碳基肥对植烟土壤微生物群落功能多样性的影响,采用田间试验研究了不同高碳基肥施用量(0、0.9、1.5和1.8 t/hm~2)处理对烟株生长发育、土壤理化性质和烤后烟叶品质的影响,并利用Biolog-ECO方法分析了土壤微生物碳代谢多样性特征。结果表明:(1)0.9～1.5 t/hm~2高碳基肥显著促进了烤烟株高、茎围、最大叶面积和根系干重等指标,1.8 t/hm~2施用量促进效果明显降低;(2)与对照相比,施用高碳基肥能够降低土壤含水率、提高土壤pH值和微生物量碳氮比;(3)Biologe-ECO分析表明,土壤微生物平均颜色变化率和多样性指数均以施用高碳基肥1.5 t/hm~2处理最高,同时土壤微生物对氨基酸类、聚合物类、碳水化合物类和羧酸类碳源利用率亦有显著提高。主成分分析表明,施用高碳基肥显著改变了土壤微生物功能群落结构,且以1.5 t/hm~2高碳基肥处理下微生物碳代谢多样性得分最高;(4)施用高碳基肥能够改善烤后烟叶化学品质,以1.5 t/hm~2处理效果最佳,总糖、还原糖和钾含量分别较对照显著提高22.81%、35.72%、25.61%。综合来看,许昌烟区高碳基肥的最适宜施用量为1.5 t/hm~2。
