Abstract

Field3414experiments in N,P and K fertilizer effects on potato were conducted in Pingtan county in 2009.The results indicated that nitrogen fertilizer application had the best yield-increasing effect on potato(yield-increasing rate 101.5%),followed by phosphor fertilizer(16.7%) and potassium fertilizer(16.1%).The quadratic polynomial regressive models of fertilization effects in three experimental plots were simulated.According to the constructed models,the optimum application rate of N,P and K fertilizer for potato was put forward.
