化学杀雄是配制杂交小麦的一个重要手段。中国科学院广州化学研究所研制合成的新化学杀雄剂均三嗪二酮,其化学名称是3-对氯苯基-6-甲氧基-均三嗪-2·4(1H,3H)二酮。1981—1982年小麦生长年度内,我们用它进行了诱导小麦产生雄性不育的试验研究。供试品种(品系)分两部分,第一部分六个品种(品系)于3月6日由大田移栽到塑料大棚;第二部分六个品种(品种)在大田自然生长。在小麦旗叶抽出叶鞘,旗叶叶 Chemical kill male is an important means of formulating hybrid wheat. The new chemical maleicide s-triazine dione developed by the Guangzhou Institute of Chemistry, Chinese Academy of Sciences, whose chemical name is 3-p-chlorophenyl-6-methoxy-s-triazine- 2,4 (1H, 3H) ketone. In 1981-1982 during the growing year of wheat, we used it to conduct experimental studies on the induction of male sterility in wheat. The test varieties (strains) are divided into two parts. The first part of the six varieties (strains) transplanted from the field to the plastic greenhouse on March 6; the second part of the six varieties (varieties) natural growth in the field.
