摘　　要：采用田间大区对比试验,对天缘活菌母露微生物菌剂在烤烟生产中的最佳用量进行了研究。结果表明,施用天缘活菌母露后,堆肥中有机物分解加速,施用1 000 mL/667m2的微生物菌剂可增加土壤速效钾含量125.00%;施用500 mL/667m2的菌剂可分别提高土壤速效氮、速效磷含量91.61%、121.62%,土壤容重减小,熟化程度增加;施用2 000 mL/667m2菌剂可使土壤容重减小12.13%,催进根系生长。1 000 mL/667m2的菌剂用量可最大增加根系干重73.61%,产量、产值、均价、上中等烟率分别提高26.32%、59.33%、26.59%和5.66%。烟叶的香气质、香气量指标得分增加,烟叶可用性增强。综合来看,在烤烟生产中,天缘活菌母露微生物菌剂以1 000 mL/667m2的用量效果最佳。The optimum application rate of tianyuan living-bacteria solution on flue-cured tobacco growth was investigated by large scale field experiments.The result showed that the decomposition of organic matter in composting accelerated after application of microbial agents.Application of 1 000 mL/667m2 microbial agents could increase the soil available K content by 125.00%.500 mL/667m2 enhanced contents of available nitrogen by 91.61% and available P by 121.62% in soil.The soil density decreased and the degree of soil maturation was accelerated.Application of 2000 mL/667m2 microbial agents could decrease the soil density by 12.31%.Application of 1 000 mL/667m2 microbial agents could extremely increase weight of dry root 73.61%.By applying 1 000 mL/667m2 microbial agents,the indices of yield per 667 m2,production value,mean price and first-class tobacco leaves proportion increased to 26.32%,59.33%,26.59% and 5.66%,respectively.The score of aroma quantity and quality increased.The availability of tobacco leaf enhanced.In conclusion,application of 1 000 mL/667m2 microbial agents was the optimized volume to flue-cured tobacco production.
