摘　　要：利用2013~2015年21点次夏花生五区丰缺试验数据,建立土壤磷钾养分与相对产量的数学关系模型,确定南阳盆地夏花生土壤磷钾养分丰缺指标,应用县域测土配方施肥专家系统,计算磷钾肥配方用量,并在2016~2018年进行验证评估和示范应用,为建立和完善测土配方施肥指标体系提供依据。Based on the five treatment fertilizer experiment data from 21 sites, we established the evaluation models for relative yield of summer peanut with the content of P, K in soil, and made the abundance and deficiency index of P and K in Nanyang basin. With the expert system of soil testing and fertilizer recommendations at county level, the formula dosage of P and K fertilizer was calculated, and verified, evaluated and demonstrated for application from2016 to 2018, so as to provide basis to establish and perfect the measuring soil fertilizer system.
