Abstract

Rice3414NPK fertilizer test was conducted to study the effect of different NPK ration on rice yields and the optimum fertilizing amount and the optimum NPK proportioning,with the local major rice variety Liaoxing NO.1 as the study subject.The results indicate that in this area the best economic output is 725.5 kg /667 m2,the optimum fertilizing amount of NPK is N 16.1 kg /667 m2、P2O5 8.5 kg /667 m2 、K2O 7.3 kg /667 m2,and the optimum NPK proportion is 1:0.53:0.45.
