以福建优质烤烟云烟87为研究对象，通过四因素五水平二次通用旋转组合设计试验，进行单因子和双因子交互效应分析，探讨N、P、K、S配施对产量的影响。单因子效应分析表明，随N、s水平增加，产量先提高后下降；随K水平增加，产量先下降后提高；随P水平增加，产量提高。双因子互作效应分析表明，N×P、N×S,P×K、P×S、K×S双因子互作之间，都存在一定的值域，值域范围内存在协同促进作用，超过值域范围，双因子之间存在拮抗作用；N×K双因子互作间，始终存在拮抗作用。优化结果表明，盆栽适宜施肥量为N肥3．778-4．350g·盆^-1、P肥3．608-4．125g·盆^-1、K肥9．860-11．635g·盆^-1、S肥0．818-0．942g·盆^-1，对应的N、P、K、S肥配比约为1：1：2．5：0．2。

To explore the influence of N, P, K and S mixing fertilization on output of tobacco leaves, a quadratic general rotary unitization design of four factors and five levels was carded out to analyze the single-factor and double-factor effect on Yunyan 87, a high quality tobacco variety in Fujian. Single-factor analysis showed that the output of tobacco leaves increased and then decreased gradu- ally with the increase of the nitrogen and sulfur application respectively, but reversea in the case of potassium, and it always kept going up in the case of phosphorus. Interaction analysis indicated that there existed synergistic effects beween N and P, N and S, P and K, P and S, K and S in a certain range, however, there existed antagonistic effects in the lower and higher range. But the an- tagonistic effects always existed between N and K. The optimal amount in the pot experiment was 3.778 to 4.350 g per pot for N, 3. 608 to 4.125 g per pot for P, 9.860 to 11.635 g per pot for K, 0.818 to 0.942 g per pot for S respectively, and the corresponding ratio of N, P, K, S was about 1：1：2.5：0.2.
