摘要
Abstract
In order to further clarify the application effects of different plant growth retardants in the late tillering stage of rice,this paper selected three plant growth retardants registered on rice (10％ uniconazole SC,5％ prohexadione calcium SC,and 30％ paclobutrazol·mepiquat chloride SC) to verify their effects on lodging resistance and yield of rice. The results showed that all three plant growth retardants could effectively reduce the height of rice plants,and signifi-cantly increase yield. Among them,30％ paclobutrazol·mepiquat chloride SC 90 g/hm2 (effective ingredient) had the best inhibitory effect on rice plant height and lodging resistance. The inhibition rate of plant height and lodging resistance effect were 6.80％ and 72.8％,respectively,and the rice yield increase rate reached 8.9％. The three tested reagents selected in this study could all be promoted and applied in production,helping to achieve high and stable yields in rice.关键词
