[Method] A field plot experiment was conducted to study the effects of the Engran series of microbial organic fertilizers on growth and development, diseases and pests and economic traits of flue-cured tobacco. [Result] The result showed that the treatment of conventional fertilization ＋ Engran microbial agent could promote the growth and dry matter accumulation of flue-cured tobacco during the growth period in the field, enhance the disease resistance of tobacco, and improve yield and output value of flue-cured tobacco and income of tobacco growers. Compared with T1,the proportion of high-grade tobacco, the proportion of mid-high grade tobacco,yield, output value and average price increased by 4.4%, 3.8%, 5.48%, 11.51% and5.73% respectively. [Conclusion] The treatment of conventional fertilization ＋ Engran microbial agent showed outstanding performance, is optimum for field production,and could be applied to Flue-cured tobacco.展开更多
