摘　　要：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。Taking Gaillardia aristata,Coreopsis drummondii and Liatris spicata as test materials,to compare the allelopathy strength of three kinds of ground-cover chrysanthemum from seed germination and seedling growth,which were planted according to a set of two and alone.The results showed that under mixed cropping,Gaillardia aristata growth was promoted.The allelopathy strength was Coreopsis drummondiiLiatris spicata;Coreopsis drummondii growth was inhibited.The allelopathy strength was Gaillardia aristata〉Liatris spicata;Liatris spicata growth was inhibited.The allelopathy strength was Coreopsis drummondii〉Gaillardia aristata.
