Title: Preliminary report on the fertilizer efficiency experiment "3414"of potato in Xiapu County,Fujian Province
Abstract: Fertilizer efficiency experiment3414of potato in particular experimental conditions showed that nitrogen,phosphorus and potassium fertilizers influenced the yield of potato,and nitrogen fertilizer had more effect than phosphorus and potassium fertilizers.Through establishing and analyzing the regression equation,it was discovered that there was an extremely significant ternary quadratic regression relation between potato yield and the fertilizing amounts of nitrogen,phosphorus and potassium.When the recommended amounts of fertilized nitrogen,phosphorus and potassium were respectively 201.12,40.78,324.16 kg·hm-2,the economic yield of potato was the highest for 34069.89 kg·hm-2.When the recommended amounts of fertilized nitrogen,phosphorus and potassium were respectively 191.80,44.42,285.55 kg·hm-2,the profit of potato fertilization was the best for 78548.4 yuan·hm-2 in RMB.
