摘要
测定了吉林省通化产六年生北细辛不同生育时期挥发油与营养元素的积累量,并通过SAS软件进行相关性分析。结果表明:北细辛挥发油含量与氮、磷、钾含量间呈显著的正相关,且与磷的相关系数最大,达0.893 5,呈极显著正相关,与氮相关系数为0.580 4,与钾的相关系数为0.508 5。在与其他微量元素的相关性比较中发现,硫与挥发油的相关系数较大,为0.629 5,超过与氮和钾的相关系数,但其显著性概率较低仅为0.069 3。经回归分析,挥发油与营养元素间的函数方程为挥发油=-0.886 4+0.000 8 N+0.568 6 P-0.012 2 K-16.620 2 B-5.326 1 Zn。
The accumulation quantity of the volatile oil and nutrition element in different pefioda of aixyear-old Asarum heterotropoides var. mandshuricum grown in Tonghua of Jilin province was studied, The relativity was analyzed by the SAS software in the computer. The result indicated that the volatile o.it content of Asarum heterotropoides var. mandshuricum had a significant positive correlation with the nitrogen phosphorus and potassium content. The correlation coefficient with phosphorus was the largest, up to 0. 893 5, showing a very significant relationship, with nitrogen was 0.580 4, and with potassium was 0.505 8. The comparison with other elements turned out that the correlation coefficient of sulfur between volatile oil was greater than the that of nitrogen and potassium. But the significance probability was as low as 0.069 3. Through regression analysis, the function of equation between volatile and nutrienta was volatile= -0.886 4＋0.000 8 N ＋ 0.568 6 P- 0.012 2 K- 16.620 2 B- 5.326 1 Zno
