前言在近年来新发现的大量除草剂中,特别引人注目的是均三氮苯衍生物。此类化合物在化学除草领域中开辟了新途径,指出了新方向。因此,从1955年第—篇报告发表后,立即引起了人们的极大兴趣,有关其合成、生理机制、使用方法以及除草效果等方面的研究相继蓬勃开展起来,一些品种在农业生产上已开始大量应用,而新的品种仍不断出现。考究其原因乃在于此类除草剂对于不同作物具有高度的选择性,杀草范围广,残效长,对人、畜无毒,使用方便。
Preface Among the numerous herbicides newly discovered in recent years, the triazine derivatives are of particular interest. Such compounds have opened up new avenues in the area of chemical weeding and pointed out new directions. Therefore, immediately after the publication of the first report of 1955, great interest has been aroused. Studies on its synthesis, physiological mechanisms, methods of use and herbicidal effects have been vigorously carried out. Some varieties have begun to be started in agricultural production A large number of applications, and new varieties are still emerging. Exquisite reason is that such herbicides for different crops with a high degree of selectivity, a wide range of grass-killing, residual effect long, non-toxic to humans and animals, easy to use.
