摘要
Abstract
Using Japanese yam as test material , the effects of N , P and K formula fertilization on yield of yam were studied .The results showed that proper application of nitrogen , phosphorous and potassium fertilizer could increase the yield of yam , while excessive application would result in the yield decline .There was sig-nificant regressive relation between the yield of yam and the application amount of nitrogen , phosphorous and potassium fertilizer.According to the fertilizer effect equation , the maximum yield of yam per 666.7m2 was 3 125.76 kg and corresponding application amount of N , P2 O5 , K2 O was 65.92, 32.62, 65.82 kg respec-tively;the optimal economic yield of yam per 666.7m2 was 3 093.25 kg and corresponding application amount of N, P2O5, K2O was 56.11, 26.34, 44.12 kg respectively.关键词
