在杂交水稻两段育秧的不同时期用不同浓度烯效唑喷施叶片 ,通过考查秧苗素质和测定生理指标及产量 ,表明在第一段秧田的 1叶 1心期和寄秧 1 5d后两次用 1 0 0 mg/ L烯效唑处理 ,可培育出多蘖壮秧 ,秧苗移栽本田后生理代谢增强 ,叶片的叶绿素含量和光合速率提高 ,后期灌浆速率增大 ,有效穗增加 .杂交水稻育秧施用烯效唑增产显著 . In the two stages of hybrid rice seedling growth with different concentrations of uniconazole spraying leaves, by examining the quality of seedlings and physiological indicators and yield measurements showed that in the first paragraph of seedling leaf 1 heart and seedling 15 days after two After the treatment with 100 mg / L unifloxacin, more tillering seedlings could be harvested, the seedling transplanting Honda increased the physiological metabolism, the chlorophyll content and photosynthetic rate of the leaves increased, the filling rate increased and the effective panicle increased at the later stage. Seedling application uniconazole yield significant.
