摘要
用赤霉素在头季稻齐穗后、头季稻收割后各个不同时期喷施和在再生稻始穗期不同时段喷施,研究其促芽促苗及增产效果。结果表明：施用赤霉素都有一定的促芽促苗效果和增产效果。以头季稻齐穗后30 d喷施、头季稻割后5 d喷施和再生苗抽穗10%～50%时喷施的综合效果较好。
Through spraying GA at different stages after heading, after harvest of first season rice and before heading of ratoon rice, the effects of its promoting seedling,germination and increasing yield were studied.The results showed that GA administration had a certain effect on promoting seedling, germination and increasing yield. Among them,it had good effects that spraying GA at 30d after heading, 5d after harvest of first season rice and heading 10% to 50% of ratoon rice.
