摘要： 为了探索不影响后作烤烟最佳移栽节令而获得大麦最高产量，确定不同播期下产量的主要决定因子，以云南省主推多棱大麦品种‘保大麦8号’为供试材料，设6个播期，观察生育进程及产量情况，并通过相关分析、通径分析及灰色关联度分析，研究不同播期烟后大麦主要农艺性状与产量相互间的关系。结果表明：（1）随着播期的推迟，生育进程也相应顺延；播种至出苗所需天数随着播期推迟而增加；（2）烟后大麦最佳播期为9月30日—10月10日；（3）通过相关分析、通径分析及灰色关联度分析，有效穗和千粒重是影响烟后大麦产量的主要因素。

Abstract: To obtain the highest yield of barley without influencing the best transplanting season of preceding crop tobacco, the major determinant factors of yield at different sowing dates were determined, the barley variety‘Baodamai 8’mainly promoted by Yunnan Province was used as test material and 6 sowing dates were set to observe the growth process and yield. Through the correlation analysis, path analysis and grey correlation analysis, the relationship between the main agronomic characters and yield of barley after tobacco at different sowing dates was studied. The results showed that: (1) with the delay of sowing date, the growth process was delayed; the days from sowing to seedling emergence was increased along with the delaying of sowing date;(2) the best sowing date of barley after tobacco was September 30 to October 10; (3) the results of correlation analysis, path analysis and grey correlation analysis showed that the effective panicle and thousand-grain weight were the main factors affecting the yield of barley.
