摘　　要：为明确烟杆碳基肥与拮抗微生物肥料复配对烟草生长和抗性的影响,本研究在重庆市奉节县烟草基地开展小区试验,利用烟杆碳基肥与多粘类芽孢杆菌和枯草芽孢杆菌复配,调查不同施肥处理对烟株农艺性状、抗病性及产量产值的影响.结果表明,烟杆碳基肥结合多粘芽孢杆菌和枯草芽孢杆菌1 kg/666.67 m^(2)复配对烟株生长有一定的促进作用;烟杆碳基肥对土壤酸化改良的效果较为稳定,处理50 d土壤pH值提高了0.64和0.61;烟杆碳基肥综合防控方案对根黑腐病的防治效果为67.8%.烟杆碳基肥与拮抗微生物的协同效应对提升烤烟产量及品质、增强烤烟抗病害能力与农业废弃物资源化利用均具有重要意义.To clarify the effects of tobacco stem carbon based fertilizer compounded with antagonistic microbial fertilizers on tobacco growth and resistance,a plot trial was conducted at a tobacco base in Fengjie County,Chongqing.Tobacco stem carbon based fertilizer was selected to be compounded with Bacillus polymyxa and Bacillus subtilis.The effects of different fertilization treatments on agronomic traits,disease resistance and yield production value of tobacco plants were investigated.The results showed that application of tobacco stem carbon based fertilizer combined with Bacillus polymyxa and Bacillus subtilis at 1 kg/666.67 m^(2) had a certain promotion effect on the growth of tobacco plants.The effect of tobacco straw biochar on improvement of soil acidification was relatively stable,with soil pH increased by 0.64 and 0.61 units in 50 days of treatment.The efficacy of integrated control program with tobacco straw carbon based fertilizer on the control of root black rot was 67.8%.The synergistic effect of tobacco straw charcoal-based fertilizer and antagonistic microorganisms is important for improving the yield and quality of roasted tobacco,enhancing the disease resistance of roasted tobacco plants and the resource utilization of agricultural waste.
