本文根据变量理论分布对区试中b值及CV值参数的数量分类,提出了适于目前普及推广的查表计算法。在此基础上,对区试品种提出了按主要生产性能指标以量定性的评定分类体系。从而推出可排除主观随意性干扰、较为完整严密的区试汇总模式,并以范例作了运用说明。 Based on the quantitative distribution of the b value and the CV value of the regional test in the theory of variable distribution, this paper proposes a look-up table method which is suitable for popularization. On this basis, the classification system of the regional test was put forward based on the quantitative evaluation of the main production performance indicators. In this way, the district examination summary model that can eliminate subjective and arbitrary interference and has a more complete and rigorous model is introduced. An example is given to illustrate the application.
