采用二次通用旋转回归组合设计方案,研究亚麻阿里安产量与有效茎、茎重和施肥量(N、P、K)之间的关系,建立各性状、各因素与产量指标间的数学模型,确立了亚麻阿里安高产(即产量在12000kg/hm2以上)栽培的有效茎、茎重和施肥量的方案是:有效茎1891～1950万株/hm2、茎重0.55～0.70g/株、纯N施用量144.5～182.3kg/hm2(即尿素314.13～396.30kg/hm2)、P2O5施用量118.5～137.1kg/hm2(即16％过磷酸钙740.63～856.88kg/hm2)、K2O施用量177.8～205.7kg/hm2(即50％硫酸钾355.6～411.4kg/hm2),其中N∶P2O5∶K2O的最佳比例1.3∶1∶1.5.各性状对产量的影响依次是茎重＞有效茎,各因素对产量的影响依次是钾肥＞氮肥＞磷肥.%The relationship between yields, effective stems and stem weight and the fertilizers of N, P,K was analyzed through a quadratic rotational regression combination design, and the mathematic models of the correlation of plant traits, fertilizer factors and yields were created. The high yield design scheme by which the yield is over 12000g/hm2 was set up,the effective stems were 18.91 -19.5 million plants/hm2, stem weight was 0.55-0.70 g/plant,fertilizer N was 144.5-182.3 kg/hm2,P2O5 was 118.5-137.1 kg/hm2,K2O was 177.8-205.7 kg/hm2. The best ratio of N: P2O5: K2O was 1.3: 1: 1.5. The influence of stem weight on yield was more evident than effective stems, the order of influences on yield was K2O>N>P2O5.
