采用“3414”最优饱和设计方案，于2014年在辽宁省农科院以氮（纯 N）、磷（P2O5）、钾（K2O）肥为探讨因子进行田间试验。探讨氮、磷、钾肥3因素对食葵杂交种丰葵杂1号株高、盘径、茎粗和叶片数的影响。结果分析表明，施入不同配比的氮、磷、钾肥对食葵的株高、盘径、茎粗和叶片数等农艺性状有很大的影响：氮肥能有效地促进食葵的株高增加，而磷、钾肥在株高达到一定高度后，超量施入则降低株高；配施不同水平的氮、磷、钾肥均能增大食葵丰葵杂1号成熟期的盘径，而超量施用则降低盘径。氮、磷、钾肥增施能有效地增加成熟期茎秆的直径，而超量施肥则降低茎秆的直径。增施氮肥能持续有效地增加食葵的叶片数，而磷、钾肥的过量施入则会降低其叶片数。

Using the "3414" optimal saturated design scheme, a field experiment was conducted with nitrogen(N), phospho-rus (P2O5), potassium (K2O) fertilizer as the exploratory factors in Liaoning Provincial Academy of Agricultural Science in 2014 to explore the effects of nitrogen, phosphorus and potassium fertilizer on the agronomic characters, such as the plant height, disc diameter, stem diameter and leaf number, of the confectionery sunflower hybrid "Fengkuiza No.1". The result showed that the application of nitrogen, phosphorus and potassium fertilizer at various ratios had great effects on the agro-nomic characters, such as the plant height, disc diameter, and stem diameter and leaf number, of the confectionery sunflow-er. The nitrogen fertilizer could promote the growth of the plant height of the confectionery sunflower and the excessive use of phosphorus and potassium fertilizer when the plant height reached a certain height would decrease the disc diameter. The application of nitrogen, phosphorus and potassium fertilizer at various ratios all could increase the mature stage' disc diameter of the confectionery sunflower hybrid "Fengkuiza No.1" and the excessive use of them would decrease the disc diameter. The increased application of nitrogen, phosphorus and potassium fertilizer could effectively increase the stem diameter of the ma-ture period and the excessive use would decrease the stem diameter. The increased application of nitrogen fertilizer could continuously and effectively increase the leaf number of the confectionery sunflower and the excessive use of phosphorus and potassium fertilizer would decrease the leaf number.
