一、引言由土壤成分引起除草剂钝化的问题已经过多年的研究。吸附作用曾被认为是土壤中影响除草剂功效的最重要的因子之一。Bailey等人认为,土中有机质和粘性矿物质都具有很好的吸附性能。已研究出几种钝化除莠剂的方法。1956年Sund发现杀草强(3-氨基-1、2、4-三氮茂)与一些金属形成稳定的络合物。 I. INTRODUCTION The problem of herbicide deactivation caused by soil constituents has been studied for many years. Sorption has been considered as one of the most important factors affecting the efficacy of herbicides in the soil. Bailey and others believe that soil organic matter and viscous minerals have good adsorption properties. Several methods of passivating herbicides have been developed. In 1956, Sund was found to be strong (3-amino-1,2,4-triazamam) to form a stable complex with some metals.
