品种试验的对象是参试材料,参试材料的数量、质量、区域及对照品种选择,直接关系试验目的的成效。本文仅就目前我省品种区域试验的参试材料问题进行浅议,供商榷。 1 参试材料数量参试材料的多少要根据目前试验点的试验地条件,试验设备手段及技术人员力量而定,必须适量。当前看主要有三个问题:一是试验材料数量过多,如小麦、有的年份一个点多达50多份,超过了试验点的承受能力;二是年际间差数太大,以小麦为例,实行二年一轮试验制的“大小”年间相差20多份,打破了试验地四区轮作的
Species test is the test material, the number of test materials, quality, selection of regions and control varieties, the test results directly related to the effectiveness. This article only on the current varieties of regional trials in our province to discuss the issue of materials for discussion. 1 The number of test materials The number of test materials according to the current test point conditions of the test site, test equipment and technical staff strength may be appropriate. There are currently three main problems: First, the test material is too much, such as wheat, and some as many as 50 points a year, more than the test point of capacity; Second, the difference between the years too much to wheat For example, there was a difference of more than 20 between the “size” and “year”
