    施肥与喷多效唑对水稻秧苗生长的影响

    Effect of fertilization and spraying paclobutrazol on the growth of rice seedlings

      摘要
    • 摘要: 研究施肥和喷多效唑对水稻秧苗株高、叶龄的影响,结果表明:施肥有利于增加水稻秧苗株高,喷施多效唑则有利于降低株高,施肥和喷施多效唑均能增加叶龄,其中单施化肥对秧苗提高株高效果最好,施肥并在1叶1心期喷300 mg/kg多效唑对增加秧苗叶龄效果最好,而不施肥且1叶1心期喷300 mg/kg多效唑对抑制株高效果最好。

       

      Abstract: Effect of fertilization and spraying paclobutrazol on plant height and leaf age of rice seedling were studied. The results showed that fertilization could increase but spraying paclobutrazol decrease the plant height, and both two could increase the leaf age. Among which, applying only fertilizer had the best effect of increasing plant height; applying fertilizer and applying 300 mg/kg paclobutrazol (drug/water) at period of 1 leaf with 1 bud had the best effect of increasing leaf age, whereas non-fertilization and applying 300 mg/kg paclobutrazol at period of 1 leaf with 1 bud had the best effect of depressing plant height.
