Abstract Split-plot designs are very popular in agricultural experiments where two factors require different sizes of plots. In traditional split-plot designs, main plot treatments are allocated using a randomized complete block design and subplot treatments are allocated within each main pot. However, often it may not be feasible to accommodate all the subplot treatments in each main plot. The purpose of this article is to propose a method of construction of such incomplete split-plot designs. Method of analysis of such incomplete split-plot designs is also presented. Construction and analysis methods are implemented using R language.

不完全裂区设计：构造和分析

摘要 裂区设计在农业实验中非常流行，其中两个因素需要不同大小的地块。在传统的裂区设计中，使用随机完整区组设计分配主小区处理，并在每个主盆内分配子小区处理。然而，在每个主地块中容纳所有子地块处理通常是不可行的。本文的目的是提出一种构建这种不完整裂区设计的方法。还介绍了这种不完整裂区设计的分析方法。构造和分析方法使用R语言实现。
