黄瓜为雌雄同株异花受粉植物,在制配一代杂种种子时,母本需要去雄,为了免除人工去雄的麻烦,降低制种成本,多年来我们使用了化学杀雄剂——乙烯利进行杀雄,并进行空间隔离方法制配黄瓜杂种一代。1974年~1981年在京郊社队大面积制配一代杂种田中,按我们的方法,使用了北京农药二厂1978年前所生产的40%乙烯利液体对母本进行杀雄,杀雄效果甚好,制种田获得了好收成。但1982年我们在京郊制种基地13个队60亩“京旭一号”及“长青”制种田中仍按原法使用农药二厂1981年10月22日生产的40%乙烯利(紫红标签)进行杀
Cucumber is a hermaphrodite flower plants, in the preparation of the first generation of hybrid seeds, the male need to decontaminate, in order to avoid the trouble of artificial deoxiong, reduce the cost of seed production, over the years we used the chemical maleicide - ethephon To kill the male, and space isolation method cucumber hybrid generation system. From 1974 to 1981, in a large area of suburbs in Beijing suburbs, a large number of communes and communes were used to produce the hybrid generation Tanaka. According to our method, 40% ethephon produced by Beijing Pesticide Factory before 1978 was used to kill male and kill male Very good, well-harvested farming system. However, in 1982, we established 13 bases of 60 acres of “Beijing Asahi One” and “Evergreen” seed production bases in the suburbs of Beijing and still used the first pesticide plant 40% ethephon produced on October 22, 1981 Purple label) to kill
