摘　　要：裂区试验设计是农业试验中一种常用设计,但其统计分析却很复杂,尤其是互作项的多重比较分析较为困难。本文采用SAS软件中的线性混合模型程序分析裂区试验设计数据,不用额外编程,只需设置其内置的语句即能够较为快速便捷地实现裂区试验设计中的统计结果分析。Split-plot design is a commonly used design in agricultural experiments,but its statistical analysis is very complicated.Especially,multiple comparisons of interaction terms are difficult.In this paper,a procedure of SAS linear mixed model was used to analyze the data of split-plot design.No additional programming was required,and only the built-in statements were needed to set.It could easily realize the statistical analysis of the split-plot design.
