| Abstract: | The plot experiment was carried out to study the effect of ratio of nitrogen,phosphorus and potassium on the yield and agronomic traits in rice,and the results showed that the rational ratio of three elements could improve growth status of rice and increase yield.Relying on regression analysis,the optimum fertilizer amounts for the optimum yield were obtained,the ratio of output to cost rose and finally the benefits were increased. |
