| 摘 要： | 采用协方差分析方法，对油菜山除草剂的试验结果进行了分析。结果表明，与按单因素试验方差分析相比，协方差分析方法可以减小因杂草田间分布不均匀而导致的调查误差。针对随机取样中的各样方内杂草数目不一致问题，讨论了统计控制方法在除草剂药效评价中的重要性以及计算过程。

| Abstract: | Covariance analysis was used to analyze herbicide efficacy data from rapeseed experiments. When compared with single factor analysis of variance, covariance analysis reduced efficacy evaluation error resulting from uneven weed distribution in the field. This paper deals with the problem of non-uniform weed numbers obtained with all types of random sampling methods, discussing the importance of statistical control methods in herbicide efficacy evaluation and showing pertinent calculations. |
