摘要
试验结果表明，低施肥量的烟草质量较好，对抑制气候斑病的效果也较好，但产量偏低。当地水田种烟以每公顷施Ｎ１０５．１２０ｋｇ，肥料配比以Ｎ：Ｐ＿２Ｏ＿５：Ｋ＿２Ｏ＝１：１：２－３对提高烟草的产量和质量以及抑制其气候斑病发生的效果较好。
The experiment of different fertilizer treatments was conducted on tobacco in Nanx-iong County from 1992 to 1993.The results indicated that low fertilizer supply was beneficial to im-prove tobacco quality and control weather fleck on tobacco leaves also. But tobacco yield was low. It was better to apply N 105-120kg per hectare and the ratio of N:P_2O_5:K_2O=1:1:2-3in local paddy field where tobacco was planted , which would raise the tobacco yield and quality,and also control weather fleck on tobacco leaves.
