去杂,是玉米杂交制种的关键技术措施之一。实践中,播前拣去杂籽,间苗时去杂苗,收获时去杂穗,都比较易行,唯独散粉前拔除杂株较难,其原因是制种单位不但要种子质量高,而且还要尽可能多收粮食,拔除杂株的方法是顾此失彼。为克服二者矛盾,一举两得,一九七三年,我社在玉米集中制种的基础上,改用“记杂去雄”的方法。实践结果,简单易行,效果良好,深受制种队干群的欢迎。
Going to miscellaneous, is one of the key technical measures for hybrid seed production in maize. In practice, before sowing to sowing seeds, seedlings to go to the seedlings, Harvest to go spike, are relatively easy, except before the loose powder unplug the hybrid plant more difficult because of seed production units not only to high seed quality, and But also as much as possible to receive food, unplug the method is to take care of one another. In order to overcome the contradiction between the two, we got twice as good. In 1973, on the basis of centralized seed production by corn, we switched to the method of “remembering others and going unpunished”. Practical results, simple, effective, well received by the seed production team.
