To study the interspecies allelopathy of Glycyrrhiza uralensis and Caragana microphylla and reveal the relationship between different interactions and provided the theory reference for their application of compounding planting pattern in practice.
Water extracts of G. uralensis and C. microphylla root, stem and leaf were used to dispose mutual seeds, young seedlings and transplants.
The germination of G. uralensis seed wasn't restrained significantly by the water extract of C. microphylla root, stem and leaf (1-50 g x L(-1)). However, the inhibitory effect of a high concentration water extract of C. microphylla stem and leaf (50 g x L(-1) was stronger. There wasnt significant difference in the effect of the water extract of C. microphylla cast, root and stem on the growth and quality of G. uralensis transplant. Moreover, the water extract of G. uralensis root, stem and leaf can improve the germination of C. microphylla seeds and the growth of seedlings, while its effective extent didn't reach an obvious different level.
There exists no significant difference between the interspecies allelopathy of G. uralensis and C. microphylla.
研究甘草与小叶锦鸡儿的种间化感作用，揭示二者不同相互作用关系，为其复合种植模式在实践中的应用提供理论参考。
采用甘草和小叶锦鸡儿根、茎、叶的水提取物处理相互的种子、幼苗和移栽苗。
小叶锦鸡儿根、茎、叶水提取物（1 - 50 g·L⁻¹）对甘草种子萌发无显著抑制作用。然而，小叶锦鸡儿茎叶高浓度水提取物（50 g·L⁻¹）抑制作用较强。小叶锦鸡儿叶、根和茎水提取物对甘草移栽苗生长和质量的影响无显著差异。此外，甘草根、茎、叶水提取物能提高小叶锦鸡儿种子萌发率和幼苗生长，但其有效程度未达到明显差异水平。
甘草与小叶锦鸡儿的种间化感作用无显著差异。
