1、一、可重复单因素随机区组试验设计8个小麦品种的产比试验，采用随机区组设计，3次重复，计产面积25平米，产量结果如下，进行方差分析和多重比较。表1小麦品比试验产量结果（公斤）品种区组产量1110.92110.83111.1419.15111.86110.17110819.3129.12212.33212.54210.75213.96210.67211.58210.41312.223143310.54310.15316.86311.87314.18314.41、打开程序把上述数据输入进去。2、执行：分析-一般线性模型-单变量。3、将产

2、量放进因变量，品种和区组放进固定因子。4、单击模型，选择设定单选框，将品种和区组放进模型中，只分析主效应。5、在两两比较中进行多重比较，这里只用分析品种。可以选择多种比较方法。6、分析结果。主体间效应的检验因变量:产量源III型平方和df均方FSig.校正模型61.641a96.8494.174.009截距3220.16713220.1671962.448.000区组27.561213.7808.398.004品种34.08074.8692.967.040误差22.972141.641总计3304.78024校正的总计84.613

3、23a.R方=.729（调整R方=.554）这里只须看区组和品种两行，两者均达到显著水平，说明土壤肥力和品种均影响产量结果。下面是多重比较，只有方差分析达到显著差异才进行多重比较。多个比较因变量:产量(I)品种(J)品种均值差值(I-J)标准误差Sig.95%置信区间下限上限LSD1.002.00-1.63331.04591.141-3.8766.60993.00-.63331.04591.555-2.87661.60994.00.76671.04591.476-1.47663.00995.00-3.4333*1.04591.00
