摘　　要：以‘K326’烤烟为研究对象,采用漂浮育苗的方式,研究最佳配比的蚓粪基质育苗(30%蚓粪+30%泥炭+20%珍珠岩+20%蛭石)和常规基质育苗对田间烟草幼苗期、团棵期和旺长期长势及代谢酶活性的影响,以期为蚓粪基质育苗的应用提供技术参考。结果表明,在幼苗期,蚓粪基质烟草的叶鲜重、总根长、根体积、根平均直径和根系活力均显著高于常规基质烟苗;在团棵期和旺长期,蚓粪基质烟草的根系生长情况整体优于常规基质,其中根系活力均显著高于常规基质,分别增加23.50%和24.98%。但2种烟草漂浮育苗基质处理方式对成苗团棵期和旺长期的叶片氮代谢酶活性无显著差异。综上,蚓粪基质整体上促进了烟草幼苗期、团棵期、旺长期的长势,尤其对烟草根系生长指标的影响更为明显,适合作为育苗基质应用于田间烟草育苗。Tobacco is used as the experimental material,with the floating seedling culture,the effects of the best ratio of vermicompost(30%vermicompost+30%peat+20%perlite+20%vermiculite)and conventional substrate on the growth and the metabolizing enzyme activities of tobacco in seedling stage,cluster stage and vigorous growth stage were studied,so as to provide technical reference for the application of vermicompost substrate seedling.The results show that,in the seedling stage,the method of vermicompost seedling culture could significantly promote the fresh weight of leaves,total root length,root volume,root diameter,and root activity,compared with the conventional substrate seedling culture.In the cluster stage and vigorous growing stage,the root growth of tobacco with the method of vermicompost seedling culture is better than that with conventional substrate seedling culture,and the root activity could reach significant difference level,increased by 23.50%and 24.98%respectively.However,there is no significant difference in the activity of nitrogentransformation-related enzymes between the different seedling culture in the cluster stage and the vigorous growing stage.In conclusion,vermicompost substrate could promote the growth of tobacco at seedling stage,cluster stage and vigorous growing stage,and has a more obvious impact on tobacco root growth indicators,so vermicompost substrate is suitable for tobacco seedling in the field.
