增施生物菌肥对烤烟产量及内在品质的影响

Effects of Increasing Application Rate of Microbial Fertilizer on Yield and Internal Quality of Flue-cured Tobacco

田间试验结果表明:在常规施肥或者有机肥部分替代常规化学肥料的基础上,增施生物菌肥(FZB42-菌剂)能明显促进烤烟K326的生长发育,提高叶片的开片度和经济性状,改善烟叶内在品质及抽吸品质。在供试条件下,以有机肥等量替代30%化学肥料,并增施生物菌肥的效果最佳。

The results of field test showed that： on the basis of the conventional fertilization or partly replacing the conventional chemical fertilizer with organic fertilizer in the production of flue-cured tobacco K326,increasing the application rate of microbial fertilizer（FZB42） could obviously promote the growth of tobacco plants,increase the expanding extent and economic characters of tobacco leaves,and improve the internal quality and smoking quality of tobacco leaves.Under the tested conditions,replacing 30% of the conventional chemical fertilizer with the commensurable organic fertilizer combined with increasing the application rate of microbial fertilizer obtained the best economic benefit in flue-cured tobacco production.
