摘要
通过在关中灌区进行陕单8806玉米氮、磷、钾肥料三要素二次混合最优设计的施肥试验,建立了陕单8806高产高效施肥的产量和效益的数学模型。对模型进行解析,明确了陕单8806在关中灌区氮、磷、钾肥料对产量的主效应和互作效应,筛选出了陕单8806最高产量和最大利润的施肥量及高产高效施肥方案。
Experiment was carried out in Guanzhong irrigation zone of Shaanxi province to study the optimum mixture design of N, P, K fertilization factors for Shandan8806. The results showed mathematical model of high yield and benefit was established, the effects of individual and interactions on yield were determined by analyzing the model. The design of its and high yield benefit, fertilization application content of the highest yield and profit were selected.
