摘要
采用五元二次正交旋转组合设计，对亚麻纤维断裂强力与锌、铜、硼、锰和钼肥5因素的定性定量关系进行研究，建立了断裂强力与5项因子的数学模型，并对回归模型进行显著性测定。结果表明：试验断裂强力数据与所采用的二次数学模型符合，二次回归方程与实际情况拟合较好。对模型进行解析和模拟检验，最终在2155个组合方案中，农艺组合方案最优为667m^2。喷施锌肥（X1）442．0～471．5g、铜肥（X2）387．0～413．0g、硼肥（X3）303．6～320．9g、锰肥420．0-445．0g、钼肥17．6～18．8g，可获得较高的断裂强力。
To study the qualitative and quantitative relationship between the flax fiber breaking strength and 5 microelement ,including Zn, Cu, Ba, Mn, Mo by the combination design of orthogonal rotating regression,the mathematics model of the flax fiber breaking strength and 5 facters was eatablished and the significance test for the regression model was operated. The results showed that the data on the flax fiber breaking strength accorded with the quadric mathematics model and the quadratic regression equation could well fit the actual situation. The results of the analysis and simulation test on the model showed that the optimum agronomic combination of 2155 combinations that could obtained the better flax fiber breaking strength was zinc fertilizer 442.0 -471.5 g per 667 m2 ,copper fertilizer 387.0 -413.0 g per 667 m^2 ,boron fertil- izer 303.6 -320.9 g per 667 m2 ,manganese fertilizer 420. 0-445.0 g per 667 m^2 , molybdenum fertilizer 17.6 - 18.8 g per 667 m^2.
