本文应用三因素五水平最优回归设计进行人参三要素定量试验,建立了施肥效应数学模.,经[E(((|y-(?)|)/y)%)]和E/T检验,拟合度极好,预报性程度高,既合理可行,又有推广实用价值.据模型分析,氮、磷、钾配合使用时,各自的线性增产效应,钾>氮>磷,其交互效应均很明显,而三种肥料单独使用时的增产效应,则N>K>P.同时拟定了人参最高产量施肥量和最大利润施肥量.
In this paper, three factors and five levels of optimal regression design for quantitative determination of the three elements of ginseng, the establishment of a mathematical model of fertilization effect, by [E (((| y - (?) |) / Y)%)] and E / , The fitting degree is excellent and the degree of predictability is high, which is both reasonable and practical.According to the model analysis, the linear increase yield effect of potassium, nitrogen and phosphorus with the combination of nitrogen, phosphorus and potassium, the interaction effect Are obvious, and the three kinds of fertilizer alone when the yield-increasing effect, then N> K> P. Simultaneous development of the highest yield of ginseng fertilizer and maximum profit fertilizer.
