摘　　要：为探索最适合甬优 15 的穗肥施用技术，设置 6 个不同施肥比例处理进行研究。结果表明，N3 处理的产量最高，其次为 N5 处理，即全生育期氮肥用量的 30%做穗肥施用时，在始穗前 1 周左右施用较为适宜；或者全生育期氮肥用量的 40%作穗肥施用时，在始穗前 3 周和始穗前 1 周分 2 次施用的效果较好。To explore the optimum application of panicle fertilizer to Yongyou 15, six treatments （N1 -N6） were compared. The results showed that N3 treatment had the highest yield, followed by N5 treatment. Therefore, under the condition of this experiment, when 30% of the total nitrogen fertilizer was used as the panicle fertilizer, and applied at about 7 days before heading, or 40% of the total nitrogen fertilizer was used as the panicle fertilizer and applied at three weeks before heading and one week before heading, would get higher yield.
