摘    要:通过对水稻生长指标、产量和品质的分析,了解15%多效唑可湿性粉剂对水稻的影响,为生产实践提供理论依据。2012和2013年,用不同浓度的15%多效唑可湿性粉剂在水稻一叶一心期对其进行喷施处理,收获前记录数据并分析。结果发现院不同浓度的15%多效唑可湿性粉剂对秧苗的抑制率为5.92%~16.85%,水稻分蘖率和实际产量增加分别为37.04%~70.37%和5.82%~16.62%。说明多效唑可湿性粉剂对水稻的生长发育有明显的调节作用,能够显著地抑制稻株的生长、促进分蘖和提高产量;15%多效唑可湿性粉剂对水稻品质有所改善,但效果不显著。

关 键 词:多效唑  水稻  调节生长  产量  品质

Effects of 15% Paclobutrazol WP on Growth,Yield and Quality in Rice
Abstract:The study was carried out to investigate the effects of 15% paclobutrazol WP on rice growth, yield and quality, As to provide theoretical basis for production practice. A series of concentrations of 15% paclobutrazol WP were sprayed at 1-leaf stage, record data and analysis before harvest in 2012 and 2013. Results showed that 15% paclobutrazol WP the features of growth such as tillering and quantity significant increased while plant height reduced after using different concentrations of 15% paclobutrazol WP. Compared with the control, the rate tillering and reproduction increased individually 37.04%~70.37%and 15.82%~16.62%, but plant height reduced 5.92%~16.85%. Therefore, the quality of rice such as brown rice, polished rice, chalkiness degree, chalkiness percentage, amylose content and crude protein has been improved at small degree.
Keywords:paclobutrazol  rice  regulating growth  production  quality
