摘要
研究多效唑液浸种对烟后稻产量及其构成因素的影响。以中浙优8号为试验材料,采用不同质量浓度多效唑液浸种处理,结果表明不同质量浓度多效唑液浸种后均有矮化秧苗、促进分蘖、增加穗粒数,提高产量的效果,而对烟后稻生育期无影响。其中以300 mg/L的多效唑液浸种为最佳,取得较好的矮化、促蘖、增产效果。
Effects of seed soaking using paclobutrazol on yield and yield components of post-tobacco rice Zhongzheyou 8 were researched,the experiments of seed soaking treatments with different paclobutrazol concentrations were conducted,results showed that paclobutrazol decreased the seedling height,increased tillers,spikiletes number per panicle and grain production,and had no effect on rice growth duration.The optimal concentration was 300 mg/L.
