摘要: 以豫麦158为研究对象,分析不同播种量及不同喷施量多效唑处理下,其产量及群体动态特征的差异。结果表明,不同播种量和不同喷施量多效唑处理下,豫麦158成穗能力一般,千粒重比较稳定,穗粒数较多,最佳播种量为112.5~150.0 kg/hm2,喷施最佳用量为15%多效唑可湿性粉剂600~1200 g/hm2

关键词: 小麦, 豫麦158, 播种量, 多效唑

Abstract: Taking wheat Yumai158 as the research object,the differences in yield and population dynamic characteristics under different sowing rates and spraying amount of paclobutrazol treatments were analyzed.The results showed that under different treatment,Yumai158 had average spike-bearing tiller rate,stable thousand-grain weight,and more grains per spike.The best sowing rate was112.5~150.0 kg/hm2,and the best dosage was600~1200 g/hm2 of15% paclobutrazol powder.

Key words: wheat, Yumai 158, sowing amount, paclobutrazole
