摘　　要：造林实践表明落叶松混交对胡桃楸的生长具有明显的促进作用[1],而从枯死的残体释放出来是化感物质向环境释放的途径之一。本实验采用落叶松的根、皮、枝、叶水浸液,配成不同的浓度,处理胡桃楸幼苗,以研究供体对受体的化感作用,探讨落叶松水浸液是否对胡桃楸幼苗的生长起化感作用,为落叶松化感作用的全面研究提供有益的资料和数据。Afforestation practice indicates that the mixed for Larch can promote the growth for the Juglans mandshurica so that the allelochemicals material from the death residual is the main way of releasing to the environment. The aqueous extract of the root, bark, branch and leaf of Larch is mixed with the different density to treat the Juglans mandshurica seedling to research the allelopathic effect of donor to receptor. At last, the particle also discusses whether it exists the allelopathic effect of Larch aqueous extract to Juglans mandshurica seedling to provide data for the allelopathic effect of Larch.
