应用除草剂引起显著的增产,这不能仅用一个消除杂草的竞争来解释。由于这个缘故,提出了关于除草剂刺激作用的假设。但是在无检验条件下很难证明这种说法,因为要表现出相反作用因子的影响,考虑到综合的效能、刺激的问题——缺乏分析内部过程的机器而限制了研究,这就妨碍了问题的解决。最近10年来在控制条件下利用新方法研究了这个问题。已明确一些除草剂(西玛津、阿特拉津、杀草定)通常提高植物体内一系列酶的活性和蛋白质的合成,另一些(草不绿、丁炔毒草安、毒草安)则是抑制,而第三组除草剂(敌草 The application of herbicides causes a significant increase in yield, which can not be explained by just one competition to eliminate weeds. For this reason, assumptions about herbicide irritation have been proposed. However, it is difficult to prove this in the absence of test conditions, since the effect of the opposite factor is to be demonstrated, which limits the research taking into account the combined efficacy, stimulus, lack of machinery to analyze internal processes Solution. In the last ten years, this problem has been studied using new methods under controlled conditions. It has been clarified that some herbicides (Simazine, Atrazine and Smectalate) usually increase the activity of a series of enzymes and the synthesis of proteins in plants, while others (Eupatorium, Butylate, and Poison) are Inhibition, while the third group of herbicides (Diura
