| 摘 要： | 为探讨再生稻芽肥施用期，设置分期施肥试验。结果明确，由于头季顶端优势的控制，茎生腋芽至头季成熟前3d才萌发，芽肥以适当晚施为宜。试验于头季齐穗后23d施芽肥比齐穗后15d施芽肥，再生季穗数和每穗粒数增加，增产6．7％。

| Abstract: | For study on bud fertilizer application time of ratoon rice, setting test of fractional fertilization.The resuhs show that： as the apical dominance control of first season, axillary buds sprouting from stem until 3 days before maturity, bud fertilizer should appropriate late-fertilizing. Ratoon season spike number and grains per spike increasing when bud fertilizer applicates 23 days after the full heading stage of first season, rather than 15 days, the yield increase rate is 6.7 % . |
