烯效唑对花生生长调节作用研究

为了明确烯效唑对花生生长发育和产量性状的影响，于花生盛花期采用田间常规喷雾的方法，研究烯效唑对花生生物性状、经济性状及品质的影响。结果表明：盛花期经过烯效唑处理的花生主茎高度低于清水对照，对株高的抑制率在7.95%~12.27%之间；与产量相关的经济性状各处理区均高于对照处理；药剂处理区增产率9.5%~13.8%，增产效果显著。烯效唑对花生营养生长的抑制持续期较多效唑长，有利于花生的生殖生长，对花生经济产量的形成具有积极的促进作用。

Study on the Effect of Uniconazole on Regulating Growth of Peanut

Experiment of 5% uniconazole WP was conducted to evaluate the biological and economic traits of peanut with the conventional spraying method during the flowering period in peanut field. The results showed that the peanut caulis with uniconazole treatment were shorter than control with inhibition ratio among 7.95%-12.27%. The economic traits related with peanut yield with all uniconazole treatments were higher than control with increasing rate in yield among 9.5%-13.8%, and the differences were significant. The inhibiting duration to the nutrition growth of peanut treated with uniconazole was longer than paelobutrazol, and the uniconazole was conducive to the peanut-reproductive growth and played a positive role in promoting economic yields of peanut.
