裂区是一种常用的试验方法,其结果的分析通常采用方差分析。由于方差分析需要计算一系列平方和,计算量较大。极差分析是一种功效与方差分析相近的方法,但使用起来却简便得多。对于裂区试验设计,本文提供了一种基于极差分析的极差比(显著性)检验方法。首先,通过一个实例说明方法。 Split zone is a commonly used test method, the analysis of the results usually use analysis of variance. Since ANOVA requires calculation of a series of squares and large computations. Range analysis is a method that has similar efficacy and variance analysis but is much easier to use. For the split-zone test design, this paper provides a range-difference based (significance) test method. First, explain the method by an example.
