水稻‘寒优湘晴’后期不同肥料运筹对其生长和产量的影响

摘要

以‘寒优湘晴,为材料,研究后期不同肥料运筹对其生长和产量的影响.结果表明:施穗肥能促进‘寒优湘晴,植株生长,有利于干物质积累,显著提高产量；不施长粗肥的产量最高；只施长粗肥,不施穗肥的产量最低.%Field plot experiments with the rice cultivar Hanyouxiangqing' were conducted under different fertilizer treatments at later growth stage of the cultivar. The results showed that fertilization for heading could promote the growth of the rice plants,be conducive to the dry matter accumulation and significantly increase the rice yield; And the rice yield could be the highest under no top-dressing for the plants to be sturdy, but the lowest under top-dressing for the plants to be sturdy and no fertilization for heading.
