| Abstract: | The effects of different nutrient management modes on yield of early rice and nitrogen use efficiency of in field-plot experiments were studied.The results showed that combined application of fertilization of nitrogenous fertilizer(N),phosphate fertilizer(P) and potash fertilizer(K),and mixed application of organic fertilizer and inorganic fertilizer in different stages could significantly increase the yield and nitrogen use efficiency of early rice. |
