In order to effectively reduce the barrier of continuous cropping,effects of extracts from Forsythia suspensa on seed germinition and seeding growth of 3 kinds of maize were studied using indoor biometic method.The results showed that after treatment with extracts of Forsythia suspensa,germination rate of Deyu 919 and Xianyu 696 was showing no significant change at low concentrations(P0.05),but Chengxin No.1 was significantly inhibited(P0.05).The extracts fromForsythia suspensa had allelopathic effects on root length,plant height and fresh weight of maize.According to the synthetic allelopathic effects,Chengxin No.1 and Deyu919 were stronger compared with Xianyu 696.Therefore,Xianyu 696 is the best variety planting after Forsythia suspensa.
