双因素裂区试验主区双向区组的设计与分析

The Design and Analysis of Main Plot Two way Block on Two Factors Split Plot Experiment

本文给出了双因素裂区试验主区双向区组的设计与分析。这种设计在主区的两个方向上均采用随机区组设计或在主区的一个方向上采用随机区组设计，而在另一个方向上采用平衡不完全区组设计，用较少试验小区来控制主区两个方向上环境差异，减少主区的试验误差。

The design and analysis of main plot two directions block on two factors split plot experiment is shown in this paper. In this design, the random block in two directions is adopted or the ramdom block in one direction and the blanced incomplete block in another direction is adopted on main plot. So it can control circumstances difference in two directions of main plot by less plots. and reduce experiment error of main plot. it has some practical value.
