前文我们已将品种(系)产量比较试验(以下简称品比试验)问题中试验地的培养、选择,试验的设计等方面应注意的问题,作了简要介绍(见本刊1979年第九期)。下面再就试验总结中常遇到的一些问题作些介绍。一、产量结果的计算分析:目前品比试验中常用的设计,多为随机区组法和间比法,随机区组法设计的产量计算分析方法,一般农业科技人员都比较熟悉,本文从略。下面只介绍间比法的产量计算,目前采用的方法有三种:一种是完全仿照对比法分析,如每隔四个品种加一对照,自左向右排列,
Earlier, we made a brief introduction to the problems that should be paid attention to in cultivating, selecting, and designing experimental plots for the test of yield (line) yield (hereinafter referred to as product ratio test) ). Here are some of the problems often encountered in the test summary to introduce some. First, the output of the calculation and analysis: The current product than the test commonly used design, mostly random block method and the ratio method, randomized block design output calculation and analysis methods, the general agricultural science and technology are more familiar with this article slightly . The following describes only the yield calculation method than the law, the current methods used in three: one is completely modeled on the comparative analysis, such as every four varieties plus a control, arranged from left to right,
