摘　　要：为探索适宜的穗肥品种与施用量,研究不同穗肥配置对比植株性状、产量及结构、成本与效益差异。结果表明:穗肥增施钾有利于大穗形成,有利于产量获得;水稻穗肥施尿素+氯化钾或尿素+BB肥(15-15-15),效果好于单纯施用尿素、专用穗肥(34-0-6)。To explore appropriate spike fertilizer and appication rates, study different spike fertilizer combination, compared the differ- ence of plants characters, yield and yield components, costs and economic tratis of rice. The results showed that increase K fertilizer is benefical for big spike, it＇ s able to get greater yield. Growth of rice under urea ＋ KC1 or urea ＋ BB fertilizer（N -P2O5 - K2O = 15 - 15 - 15） is better than urea or special spike fertilizer （ N - P2O5 - K2O =34 -0 -6） .
