Abstract: In order to investigate the effect of multifunction soil conditioners on tobacco growth, a field experiment was conducted to investigate the effect of multifunction soil conditioners (T1 and T2) on flue-cured tobacco agronomic traits, yield, output value, the rates of disease incidence of tobacco and fertilizer use efficiency, local recommended method (CT1) and traditional lime conditioner (CT2) were used as CK. The results showed that compared with CT1, T1 and T2 treatment could improve tobacco agronomic traits and tobacco growth; the yield of tobacco significantly increased by 12.31% and 6.51% compared with that of CT1, and the proportion of first-class tobacco increased by 4.38% and 3.81% (P ＜0.01), respectively; the economic benefit increased by 1778.58 and 2129.67 yuan/hm2. Additionally, T1 and T2 treatment significantly enhanced fertilizer use efficiency, decreased the rate of disease incidence and disease index. The effects of T1 and T2 on tobacco were not significantly different from that of CT2, but the content of calcium in the former was significantly lower than that of the latter. Those evidences illustrated that multifunction soil conditioner could promote tobacco growth, increase tobacco yield, quality, economic benefit and fertilizer use efficiency, which could be applied in tobacco production in the future.
