摘　　要：应用三元二次通用旋转组合设计,采用沙培方法,在二代节能日光温室内研究了营养液配方中的NO_3-N、P、K的摩尔浓度对非洲菊产量的影响。结果表明:3个元素对非洲菊产量的影响大小顺序是:氮>磷>钾;通过计算机模拟寻优,非洲菊单株最高产量8.65枝/株时,NO_3-N、P、K 3个因子营养液的最优配方为:12、1.5、4mmol/L。The ternary quadratic form universal revolving combination design were used to research the influence between mol concentration Matching among NO_3-N,P,K in nutrient solutions and the output of gerberas in secondary greenhouse.The sand culture were used in this process.The results showed that the order of affect degree was N>P>K;Optimization of computer simulation showed that the maximum yield of gerberas was 8.65 branches per hill,the best recipe of three element among NO_3-N,P,K were prepared as follow:12,1.5,4 mmol/L.
