研究了品种和栽培模式及其互作对烤烟生长和主要质量性状的影响,结果表明:栽培模式对烤烟大田各生肓期、农艺性状和经济性状的指标贡献率最大,分别为71.5％、46.8％和64.2％；其次是品种,分别为26.7％、40.3％和22.7％.在相同品种的条件下,栽培模式2的烤烟大田生育期相对较长,农艺性状相对较好,化学成分含量适宜且有关比例较协调,产量、均价、产值、上等烟比例和中上等烟比例等经济指标均处于较高水平；在相同栽培模式的条件下,云烟87的各大田生育期和化学成分等指标中表现较优,K326在农艺性状方面表现较好；在经济性状方面,品种间没有明显的差别,由此可知,栽培模式2、云烟87、K326适合在贵州开阳推广.%The effects of variety, cultivation pattern and (heir interaction an the growth and main qualitative characters of tlue -cured tobacco were studied The results showed thai cultivation pattern had the greatest contribution rate to the indexes of growth period, agronomic character and economic character of flue -cured tobacco in the field, being 71.5% , 46.8% and 64.2% respectively; followed by variety, and its contribution rate was 26.7% , 40. 3% and 22.1% respectively. Under the condition of the same variety, flue - cured tobacco in cultivation pattern 1 treatment had relatively longer field growth period, better agronomic, characters, proper and coordinative chemical composition contents, and its such economic indexes as yield, average price, production value, fine tobacco rati-o and middle -fine tobacco ratio were at relatively higher level. Under the condition of the same cultivation pattern, Yunyan 87 had better performance in field growth period and chemical compositions, while K326 performed better in agronomic characters. There were no significant differences in economic characters among different varieties. In conclusion, cultivation pattern 2 and Yunyan 87as well as K326 were suitable for being popularized in Kaiyang, Guizhou.
