摘　　要：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K2O299.775～327.000kg/hm2产量可达4860.00kg/hm2以上。The common quadratic regression combination design was used to Raise the level of eul 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/hm2） were the planting density153. 480-173. 700 plants,amount of N of 285. 225-331. 225 kg/hm2 , K2O 299. 775-327. 000 kg/hm2.
