Abstract: Effects of different irrigation methods on neutral aromatic substance content of flue-cured tobacco leaves were studied by field experiment to screen irrigation method which can improve tobacco leaves aroma quantity. The results showed that sprinkler irrigation significantly increased middle and upper part tobacco leaves neutral aroma substance content. compared to water irrigation and furrow irrigation, sprinkler irrigation B2F grade tobacco leaves neutral aroma substance content increased by 8.1% and 42.9% respectively, C3F grade tobacco leaves neutral aroma substance content increased by 26.3% and 27.9% respectively which indicated sprinkler irrigation is a kind of optimal irrigation method for flue-cured tobacco planting, also a kind of usability way to improve aroma quantity.
