中文摘要：

以中稻品种深两优876、准两优199为材料，于2014~2016年连续3a开展不同时期（头季中稻收割前6d、收割当天、收割后5d）施用促芽肥（150kg/hm2尿素）的田间试验，通过比较中稻再生季的生育期、穗粒结构及产量的差异来确定再生季水稻促芽肥的最佳施用时期。结果表明：两个品种在头季中稻收割前6d施促芽肥的再生季产量最高，且植株生长期适中，有效穗多，穗粒结构合理。

英文摘要：

Using hybrid mid-season rice Shenliangyou876and Zhunliangyou199for the test materials,150kg/hm2urea was applied ondifferent application period of first season,including6days before harvest,the harvest of rice harvest day,and5days after bud from2014to2016,the optimal application period of rice sprout fertilizer was determined by comparing the growth period,grain structure and yieldof rice regeneration season.The results showed that the yield of both rice varieties reached the highest when applied bud fertilizer about6days before harvest in the first season,for moderate growth period,more panicle number,and reasonable spike grain structure.
