近年来,关于小麦杂优利用的研究,在国内外已受到普遍的重视。其中小麦化杀杂优利用的研究日益发展。在国外,60年代以来,先后合成和试用一些化学药品应用于小麦的杀雄试验。据文献报导,DPX3778对小麦杀雄有良好的效果。在国内,70年代以来,应用乙烯利于小麦的化杀研究较多,已取得成功,但存在一些问题尚未解决,以致未能在生产上大面积使用。我们从1977年开始,先后试验了80多种药剂,处理了10多个品种,使用了30余种浓度,经1978、1979两年重复试验,初步筛选出氨基磺酸、DPX3778、甲基砷酸钠等药剂对小
In recent years, research on the utilization of heterosis in wheat has received universal attention both at home and abroad. Among them, the research on the utilization of wheat and miscellaneous and miscellaneous miscellaneous grains is developing day by day. In foreign countries, since the 1960s, some chemicals have been synthesized and tested for the killing test of wheat. According to the literature, DPX3778 has a good effect on the killing of wheat. In China, since the 1970s, there have been more successful studies on the use of ethephon to kill wheat, but some problems have not been resolved yet, so that they have not been able to be widely used in production. We started from 1977, has tested more than 80 kinds of agents, treated more than 10 varieties, the use of more than 30 kinds of concentrations, repeated tests in 1978 and 1979 two years, the initial screening of sulfamic acid, DPX3778, methyl arsenic acid Sodium and other drugs on the small
