To clarify the optimum time and application rate of nitrogen of buds promoting fertilizer, the field experiment was carried out using the hybrid rice combinations Zhunliangyou 608 as material. The results indicated that the yield of ratoon rice was signifi-cantly affected by application time and application rate of buds promoting fertilizer. The yield of ratoon rice showed a decreased trend with the delay of application time and decline of application rate. When the nitrogen application rate was 69.0 kg/hm~2 at 15 d before the main crop harvested, it could get the higher yield and good grain quality.
