Effects of Different Plant Growth Regulators on Yield and Its Components of Ratooning Rice
摘要
Abstract
[Objective] To study the effects of different plant growth regulators on yield and its components of ratooning rice.[Method] With Fengliangyouxiang 1 and Zhongpuyouhuazhan as the experimental materials, different promoter and 920 were sprayed with 225 kg/hm2 water in the afternoon after mechanical harvesting 2 days to study yield and its components.[Result]Spraying promoter and 920 treatment can break the dormancy of regenerated bud regeneration, improve rice seedling number and spike rate, increase the effective panicles per unit area, seed setting rate, grain number per panicle and plant height, so as to improve the yield of ratooning rice, increase by 7.9%-12.7%, increase production efficiency significantly.The ratooning rice yield showed extremely significant positive correlation with grain number, seed setting rate and 1 000-grain weight ,showed significant positive correlation with species regeneration ability.[Conclusion] The research provided technical support for stable and high yield in the first season after mechanical harvesting.关键词
