裂裂区设计在肥料试验中的应用

Application of Resplitting Action in Fertilizer Test

裂裂区设计（亦称再裂区设计）是裂区原理的扩展，把副区分成副副区，并指定为第三个处理因子，试验结果表明，这种设计可以更精确地鉴定副副区的因子效应和包括这个因子在内的交互作用．一次试验可以同时鉴定出10种效应的平均数．

Resplitting action extends the theory of splitting,makes the subsection redivide and aims at the thired factor concerned.As proved by many tests,these actions can appraise more clearly than before the factor concerned in the corresponding part of the sub-section and identify the function of them.Besides,ten average figures can be found in one test.
