为提高甜叶菊的栽培技术水平、揭示密度、氮、钾肥施用量与产量的关系.采用二次通用旋转组合设计的方法,建立各因素与产量之间的回归方程,筛选高产栽培优化模式.结果表明:最佳农艺方案:种植密度153.480~173.700千株/hm2,配施纯氮285.225~331.225kg/hm2和 K2 O 299.775~327.000kg /hm 2产量可达4860.00kg/hm 2以上.

The common quadratic regression combination design was used to Raise the level of cul‐tivation techniques and study quantity relation between yield and main cul‐tivating factors ( the density and amount of N and K ) in Stevia rebaudiana Bertoni .The regression equation of the main factors and yield were established and cultivation optimization mode were filtered .The re‐sults showed that the optimum agronomic project the high yield ( more than 4860 .00 kg/hm 2 ) were the planting density153 .480‐173 .700 plants ,amount of N of 285 .225‐331 .225 kg/hm 2 ,K2 O 299 .775‐327 .000 kg/hm 2 .
