摘要
川芎喷施青霉素后,降低了植物组织水势,增强了吸水能力;提高了叶绿素含量并抑制其降解,有利于光合产物的形成;增加了营养根,提高了根冠比值,经济产量得到了较大提高;控制川芎根腐病发病在5%以下。
t
has been proved that penicillin spray on Ligusticum chuanxiong can
contribute to the growth of the plant inthe following ways:cutting
down the tissue water potential,strengtkening the capability of
sucking moisture,in-creasing the contents of chlorophyll and
restraining its degradation to facilitate the formation of
photosyntheticcompounds,enriching the nutrition root and increasing
the root-shoot ratio. All these help to keep the stem tuber-ot under
5%so as to guarantee higher economic yield of the plant.
