Efficiency test of uniconazole used for rice seed soaking and seedling spraying
Abstract：In order to study the effects of uniconazole on the rice growth,an efficiency test of uniconazole used for rice seed soaking and seedling spraying in proportion of 20 mg/kg,30 mg/kg,40 mg/kg,50 mg/kg with 5% uniconazole was carried out.The results showed that,germination and emergence rate was improved by 0.4%~8.1% and 2.7%~5.7%,respevtively to compare with control when soaking seeds in proportion of 20 mg/kg,30 mg/kg,40 mg/kg,50 mg/kg with 5% uniconazole;the rice grew better by using uniconazole to soak seeds or spray seedlings than by using paclobutrazol,showing dwarfing of stalk,wide base stem,wide leaves,increased white root per plant,earlier tillering stage by 2~4 d,more tillers,increased effective panicles per plant and yield.The proportion of 30~40 mg/kg with 5% uniconazole was recommended in the productive practice.
