以天人菊、金鸡菊和蛇鞭菊为试材,比较两两混种与单种在种子萌发和幼苗生长阶段相互间的化感效应强度。结果表明:两两混种下,金鸡菊、蛇鞭菊对天人菊生长起促进作用,化感效应强度为金鸡菊>蛇鞭菊;天人菊、蛇鞭菊对金鸡菊生长起抑制作用,化感效应强度为天人菊>蛇鞭菊;金鸡菊、天人菊对蛇鞭菊生长起抑制作用,化感效应强度为金鸡菊>天人菊。
The results showed that the allelopathic effect intensity of each mixed species with single species on the seed germination and seedling growth stage was compared with that of the other two species. The results showed that under the mixed condition of two or two, Echinochloa crusgalli and Eupatorium rosea promoted the growth of Echinochloa crusgalli, and the allelopathic effect intensity of Echinochloa crusgalli> , And the allelopathic effects were as follows: Radix Rehmanniae> Rhododendron chrysanthemum; and Coreis chrysanthemum and Chrysanthemum morifolium had inhibitory effects on the growth of Rhododendron chrysanthemum.
