摘　　要：采用"3414"二次回归设计,以氮、磷、钾为供试因子,黄瓜产量为目标函数,对贵州省低热地区早熟黄瓜施肥数学模型进行研究。结果表明,优化的施肥技术方案为N肥施用量201.75 kg/hm2、P2O5施用量121.05 kg/hm2、K2O施用量321.15 kg/hm2时,产量为79 435.05kg/hm2。The mathematical model of fertilization for earlier cucumber was studied in lower altitude areas in Guizhou Province, by taking the N,P.K as factors and the yield of cucumber as objective function in the quadratic regression design of 341g. The results showed that the optimal proportion of fertilizer was N 201.75 kg/hm^2, 17205 121.05 kg/hm^2 and K2O 321.15kg/hm^2, the yield could reach 79 435.05 kg/hm^2.
