摘要
采用拌种和齐穗期叶面喷施研究了锐劲特对水稻生长和产量的影响。试验结果表明 :锐劲特药剂拌种促进秧苗根系生长和分蘖出生 ,提高单株叶面积 ,表现增穗增产。花后叶面喷施锐劲特可延缓叶片衰老 ,提高叶片叶绿素含量和光合作用 。
Studies were carried out on effects of Regent on growth and yield of rice with seed treatment and leaf spraying.The results showed that Regent seed treatment enhanced the formation of roots of rice seedlings,increased tiller number.Compared with the control,the leaf senescence was inhibited and the leaf chlorophyll content and photosynthesis were increased by leaf spraying of Regent at heading stage.That caused the increase grain yield by increasing grain number per panicle.
