采用荧光定量PCR方法,研究生物有机肥对盆栽烟草根际青枯病原菌和拮抗菌动态变化的影响。结果表明,施用生物有机肥显著降低了抗病品种“K326”和感病品种“南江三号”烟草青枯病的发病率,促进了烟草生长,生物量增加14%以上;只接种病原菌处理(RS)土壤中青枯病原菌的fliC基因拷
The effects of bio-organic fertilizer on the dynamic changes of bacterial wilt and antagonistic bacteria in potted tobacco rhizosphere were studied by fluorescence quantitative PCR. The results showed that the application of bio-organic fertilizer significantly reduced the incidence of tobacco bacterial wilt and disease-resistant cultivar “K326” and susceptible cultivar “Nanjiang No.3” and promoted the growth of tobacco with the biomass increased by over 14% Inoculation of pathogen to treat (RS) fliC gene copy of bacterial wilt in soils
