本文针对滇中地区优质烟生产实际，采用二次饱和Ｄ－优化设计，在滇中水旱轮作条件下研究了移栽期、施肥量、留叶数三个因子对烤烟产量、质量的主效应和互作效应；建立了大田生育期、每公顷产量、上等烟比例、平均单叶重、烟碱含量和糖／碱６个指标与三因子的回归数学模型；并在８０００个方案中进行模型最优化解选出３９个方案供大面积生产应用，即移栽期５月１０～１５日，每公顷施氮量１０５～１５３ｋｇ，每株留叶数１８９～２０１片时，可满足烤烟优质适产大田生育期１１５～１２５天，每公顷产量２４７５～２７７５ｋｇ，上等烟比例６０％以上，平均单叶重８～１１ｇ，烟碱含量２％～３％，糖／碱８～１２等指标要求。
In this paper, according to the actual situation of high quality tobacco production in central Yunnan, the secondary saturation D-optimization design was used to study the main effects of three factors on the yield and quality of flue-cured tobacco And interaction effects were established. The regression mathematical model of six indicators and three factors of growth period per hectare, yield per hectare, the proportion of superior tobacco, average single leaf weight, nicotine content and sugar / alkali was established and conducted in 8,000 programs Model optimization solution selected 39 programs for large-scale production and application, that is transplanted from May 10 to 15, nitrogen application rate of 105 ~ 153kg per hectare, leaves per plant leaves 18 9 ~ 20 1 piece, Flue-cured tobacco can meet the needs of 115 ~ 125 days, yield 2475 ~ 2775kg per hectare, the proportion of superior tobacco more than 60%, the average single leaf weight 8 ~ 11g, nicotine content of 2% to 3%, sugar / ~ 12 indicators and other requirements.
