| Abstract: | A field trial on fertilizer efficiency of N-P-K compound fertilizer ＂3414＂ was carried out in Fu-an city by using virus-free potato.The results showed that the application of nitrogen,phosphorus and potassium could increase the yield of potato by 33.7%,30.9% and 12.35% respectively.Under the condition of this experiment,the highest yield of potato was 1 984.4 kg per 667 m2,its correlative fertilizer-applying proportion was 19.26 kg N,N∶P2O5∶ K2O = 1∶0.53∶1.09;the economic yield was 1 980.8 kg per 667 m2,its correlative fertilizer-applying proportion was 19.08 kg N,N∶P2O5∶K2O = 1∶0.54∶1. |
