补充资料：多年生杂草
分子式：
CAS号：
性质：寿命在二年以上，一生中能多次开花结实的杂草。主要特点是在开花结实后地上部死亡，依靠地下器官越冬，次年春季从地下营养器官又长出新株。此类杂草除能以种子繁殖外，还能利用地下营养器官进行繁殖，而后者是主要的繁殖方式。根据地下营养器官的特点，多年生杂草可以分为根茎杂草、根芽杂草、直根杂草、块茎杂草、球茎杂草、鳞茎杂草等。如车前(Plantago asiatica L.)、狗牙根[Cynodon dactylon (L.) pers. ]、香附子(Cyperus rotundus L.)、问荆(Equisetum arvense L.)等均为多年生杂草。
