为优化亚麻栽培技术，提高亚麻原茎产量，试验通过二次正交旋转设计分析了有效播种密度、氮肥、磷肥、钾肥对冬播亚麻原茎产量的影响。发现供试条件下，各因素对亚麻原茎产量的影响大小顺序为有效播种密度（X1）＞氮肥（X2）＞钾肥（X4）＞磷肥（X3），不同肥料间互作不显著。并得到优化后的亚麻高产栽培方案：有效播种密度在3454.8～3502.3万粒／hm2， N263.2～337.7kg／hm2， P2 O5用量75.5-99.7kg／hm2， K2 O用量242.5～316.8kg／hm2。%To optimize flax cultivation technique ,an experiment was carried out in winter to study the influence of effective seeding density ,nitrogen ,phosphate ,potash on flax stem field with quadratic orthogonal rotation design. Under the testing conditions ,the order of influential factors ranked as effective seeding density (X1) > nitrogen (X2) > potash (X4) > phosphate (X3) ,the interaction among the different fertilizers was not significant. The optimized cultiva-tion factors were effective seeding density of 3.5~3.5 × 106 seeds/hm2 ,N of 263.2~337.7kg/hm2 ,P2 O5 of 75.5~99.7kg/hm2 ,K2 O of 242.5~316.8 kg/hm2.
