组合拉丁方设计在田间试验中的应用

本文报道了应用组合拉丁方设计方法进行棉花品比试验的情况。结果表明：无论土壤肥力差异是单向的还是双向的，采用组合拉丁方设计都能在不增加试验耗费的条件下提高试验的效率。因此在田间试验中可以用组合拉丁方设计代替目前常用的随机区组设计。

Apply of Combined Latin Design in Field Experiment

It is reported that the Combined Latin Square Design(CLSD) was used in field experiment for comparing some cotton varities and it was confirmed that whatever soil fertile difference was showed in one or two ways, the efficience of experiment may be improved by using CLSD So that the CLSD should be used to substitute the RBD which is used generally in field experiment
