| 摘 要： | 采用二次饱和D-最优设计,建立了有机肥、氮肥、磷肥和钾肥配合施用对水稻产量影响的数学模型.研究表明有机肥施用量的过多或过少均使水稻产量下降,化肥的施用也有相似的影响;有机肥与氮肥、磷肥、钾肥只有施用量在适宜的范围内,交互作用较大,产量最高.提出了延边地区水稻获得稳产、高产的施肥体系.

| Abstract: | The paper studied the effect of mixed application of organic and inorganic fertilizers on rice yield with saturated D-optimal design for quadratic regression, and established mathematical model. The results showed that rice yield descended when organic fertilizer was applied overmuch or deficiently, and similar instance also happened when inorganic fertilizer was used. When proper amount of organic and inorganic fertilizer was put into soil, crosslinked actions increased, and rice yield was greatest in all treatment. A fertilizing plan was offered for dependable crop and high yield in Yanbian region. |
