Abstract:

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 significantly. The inhibiting duration to the nutrition growth of peanut treated with uniconazole was longer than paclobutrazol, and the uniconazole was conducive to the peanut-reproductive growth and played a positive role in promoting economic yields of peanut.
