本文介绍控制和降低试验误差的技术一统计控制。它是通过统计运算把试验条件控制在尽可能一致的基础上。首先是研究田间施肥试验的产量结果与匀田播种的前作产量的关系。其次是应用协方差分析对试验误差实行统计控制,力求各处理处于相同试验条件下的一种方法,修正试验结果,以反映肥料处理间真实的差异。文中以一个水稻施肥试验数据和其前作试验数据为例进行统计运算,以资说明统计控制技术的作用。
This article describes the control and reduce the experimental error of a statistical control. It is through statistical calculations to control the test conditions as much as possible on the basis of consistency. The first is to study the relationship between the yield of the field fertilization experiment and the pre-harvest yield of Harvest. Followed by the application of covariance analysis of statistical error control test, and strive to deal with the same test conditions in a way to correct the test results to reflect the true difference between the fertilizer treatment. In this paper, a rice fertilization test data and its previous experimental data as an example for statistical computing, in order to explain the role of statistical control technology.
