皖西烤烟栽培合理施肥问题研究

Study on Rational Fertilization for Flue-cured Tobacco Production in the Western Anhui

通过9个处理组合的田间试验，对皖西烤烟栽培中的施氮量、NPK配比和基／追肥比例等三方面问题进行了探讨。结果表明：以施氮75．0～97.5kg／ha、N：P：K为1：2：4、基／肥比例60／40较为经济合理。

The field experiment of nine treatment groups was conducted in 1994. Here nitrogen levels,the ratios of N: P: K and the ratios of basal dressing to top dressing in the cultivation of flue-cured tobacco in tbe Western Anhui were discussed. Based on the results,the rational treatment group included that the nitrogen level was 75～97. 5kg/ha;the ratio of N: P: K was 1: 2: 4 and ratio of basal dressing/top dressing was 60/40.
