摘要
通过测土配方施肥技术肥料效应田间试验,获得最佳施肥量和施肥比例,建立了花生施用氮、磷、钾的三元二次效应方程,提出达到最高产量或最大经济效益的施肥量,为花生配方施肥指标体系的建立提供依据。
Field experiments were conducted based on soil tests to study the effects of fertilizer on peanut with application of different ratios. The optimal quantity and ratio were determined, and an equation depicting the effect of nitrogen, phosphorus and potassium was established. The fertilizing quantity for maximizing yield/economic return was worked out. The standardized systematic approach to compounding application of fertilizer on peanut was set up.
