摘　　要：以不同肥力水平的壤质草旬土为基质，进行Ｎ，Ｐ、Ｋ完全设计盆栽试验。结果表明：不同肥力土壤配施Ｎ，Ｐ，Ｋ，辣椒增产效果不同．土壤肥力高的土壤，辣椒对土壤肥力的依存率为７６．９３％，中肥力土壤为６７．３３％，低肥力土壤为６２．２５％，而肥效则以低肥力土壤为最高。By the means of N,P,K complete frial method.The effects of N,P,K fetrilizerapplication on fertilizaton of pepper were studied in this experiment. The consquencesare:different effects on the yield of pepper in three kinds of loamy meadow soil with different fertility were found by the means of N,P,K complete pot trial method The dependencer atesupon soil fertility level were significantly different:76.93% at the higher,67.33% at the middleand 62.23% at the lower.The application of N, P,K could significantly increase the pepperyield on the lower level soil fertility.
