摘　　要：采用盆栽法在人工气候箱中研究了狼毒Steura chamaejasme在土壤里腐解过程中对红豆草Onobry-chis viciifolia的生化他感作用。结果表明:狼毒根和茎叶对红豆草幼苗茎叶的干质量、植株高度、叶面积具有抑制作用,其抑制效果随着狼毒用量的增加而加大;狼毒根的抑制作用大于狼毒茎叶;对红豆草的细胞质膜透性无显著作用。The allelopathic effect of Steura chamaejasme decomposing in soil on Onobrychis viciifolia was studied in a growth chamber in pot culture.The result showed that the root and stem-leaf of Steura chamaejasme inhibited dry weight of stem-leaf,leaf area and the height of Onobrychis viciifolia.The inhibiting effect was stronger with the increase of amount of Steura chamaejasme.The inhibiting effect of root was stronger than that of stem-leaf,but no significant effect on cell permeability of Onobrychis viciifolia was found.
