为优化坝上地区水浇地种植业结构，在节水灌溉栽培条件下，采取四因素正交旋转组合设计，研究了施用氮、磷、钾肥对油用亚麻产量作用效果。油用亚麻从出苗后的整个生长期降水量仅142.5 mm，比常年减少50％以上，试验降水条件属于极度干旱。通过现蕾期、开花期、灌浆期每次13.3 m3/666.7 m2关键灌水，满足了油用亚麻正常生长。通过优化解析结果表明：播种密度66.8万/666.7m2有效粒，施用氮肥12.8kg/666.7m2，磷肥7.3kg/666.7m2，钾肥6.9kg/666.7m2，油用亚麻产量最高达239.7kg/666.7m2。提出了一种适宜本地区油用亚麻节水、高产、高收益栽培模式。

In order to optimize the irrigated farming structure in Bashang area , an orthogonal rota-tion combination with 4 influential factors was designed to study the effect of density , N, P and K on the yield of linseed flax under water -saving irrigation condition.The precipitation during the growth period after seedling was only 142.5 mm, 50%less than the common years , the test condition was extremely ar-id.In order to meet the normal growth for linseed flax , 13.3m3/666.7m2 of water were irrigated during the budding period , flowering period and grouting period.The results showed that the yield could be up to 239.7kg per 666.7m2 with the density of 668 thousand effective seeds, 12.8kg N, 7.3kg P and 6.9kg K.A planting model with water -saving, high yield and high income was put forward in the local-ity.
