这个题目有没有写错?没有。不信,我们来做个简单的实验:首先,选择好一根杨树枝条(或芹菜),应该是无伤、无病,生长正常的健壮枝条,像铅笔那么粗正好。用剪刀把它从杨树上剪下来,立即插入盛有水的盆里或桶里。一定让枝条切口端浸泡在水里,这样可以防止空气从切口处进入植物导管而 Is there any mistake in this topic? No. Do not believe, let’s do a simple experiment: First of all, choose a poplar branch (or celery), it should be a harmless, disease-free, normal growth of robust branches, as thick as a pencil. Use scissors to cut it off the poplar and immediately insert it into a basin or bucket filled with water. Make sure that the cut ends of the shoots are soaked in water to prevent air from entering the plant conduit from the incision.
