我所自1974年推广应用正交设计试验法以来,在农业生产中发挥了重要的作用。实践证明,这是一种多快好省的试验方法。总结几年的实践经验提出以下几点改进意见: 一、为了便于田间操作,可将试验实施方案变换成“田间作业顺序表”的形式,当试验方案较小时(例如L_4(2～3)试验方案),直接利用实施方案在田间操作,一般不会发生处理项目的混乱和漏掉某一处理的现象。但是当方案较大时(如L_(27)(3～(13))方案等),因小区数较多、因素水平比较复杂,假如在设计中又有组
Since 1974, I promote the application of orthogonal design test method, has played an important role in agricultural production. Practice has proved that this is a much faster and better test method. Sum up several years of practical experience to make the following improvements: First, in order to facilitate the operation of the field, the experimental implementation of the program can be transformed into “field operation sequence table” form, when the test program is small (for example, L_4 Program), the direct use of the implementation of the program in the field of operation, the general treatment of the project will not occur confusion and omission of a phenomenon. However, when the scheme is large (such as L_ (27) (3 ~ (13)) scheme, etc.), because of the large number of cells, the level of factors is more complicated.
