选择种植于青海东部山旱区的白籽胡麻品种作为材料。采用饱和D-三因素最优设计方案，建立了播种密度、氮肥施用量、磷肥施用量三个因素对“张亚2号”籽粒产量的函数模型。结果表明：因素主次的顺序为氮肥〉播种密度〉磷肥，两因素交互作用最高达172kg／667m2，青海东部山旱区胡麻“张亚2号”栽培优良农艺措施组合为：播种密度4．84—5．70kg／667m2、施氮肥量6．49～7．74kg／667m2、施磷肥量5．95—6．85kg／667m2。
選擇種植于青海東部山旱區的白籽鬍痳品種作為材料。採用飽和D-三因素最優設計方案，建立瞭播種密度、氮肥施用量、燐肥施用量三箇因素對“張亞2號”籽粒產量的函數模型。結果錶明：因素主次的順序為氮肥〉播種密度〉燐肥，兩因素交互作用最高達172kg／667m2，青海東部山旱區鬍痳“張亞2號”栽培優良農藝措施組閤為：播種密度4．84—5．70kg／667m2、施氮肥量6．49～7．74kg／667m2、施燐肥量5．95—6．85kg／667m2。

The white grain flax cultivar ＂Zhangya 2＂ which planted in arid and mountainous region in east Qinghai was used as material in the study. The grain yield function model of ＂Zhangya 2＂ was constructed by applying the D-saturation optimum design with 3-factors （seeding rate;nitrogen fertilizer;phosphate fertilizer）. The result showed that the effects of 3 factors were sized as N 〉 seeding rate 〉 P;the maximum interaction of 2 factors was 172kg/667m2. The optimal agricultural measures of high-yielding cultivation of ＂Zhangya 2＂ were given as follows ： seeding rate 4. 84 - 5.70kg/667m2, nitrogen fertilizer 6.49 - 7.74kg/667m2, phos- phate fertilizer 5.95 - 6. 85kg/667m2.
