近年来,不少麦田除草都用上除草剂,省去了人工除草的麻烦,但如果使用方法不当,也会造成药害。因此一定要掌握正确的施用方法。首先,药剂配制必须采取二次稀释法,切忌先倒入药剂后加水,这样药剂容易在喷雾器的吸水管处沉积,使先喷出的药液浓度高,易产生药害,后喷出的药液浓度低,除草效果差。也不可将药剂一下倒入盛有大量水的喷雾器内,这样可湿性粉剂往往漂浮在水表或结成小块,分布不均匀,不但不能保证效果而且 In recent years, many wheat weeds are used herbicides, eliminating the trouble of artificial weeding, but if used improperly, it will cause injury. Therefore, we must master the correct method of application. First of all, the pharmaceutical preparation must take the second dilution method, avoid pouring the medicine after adding water, so that the agent is easy to deposit in the suction pipe of the sprayer, so that the high concentration of the liquid that is ejected first is easy to produce the injury and then the medicine Low liquid concentration, weeding poor.
