大麦产量与产量构成因素的灰色关联度分析

Analysis of Grey Correlation Degree on Barley Yield and Yield Components

采用灰色系统理论 ,对江苏沿江地区大麦产量与产量构成因素进行了灰色关联度分析。结果表明 :江苏沿江地区大麦产量构成因素对产量影响大小的顺序为 :穗粒数 >穗数 >千粒重。

The barley yield and yield components in Yanjiang region of Jiangsu province were analyzed with the analysis method of Grey Correlation Degree.The results showed that the sequence of yield components affecting barley yield: grains per spike> spikes>1?000-grain weight.
