摘　　要：为研究问荆(Equisetum arvense L.)是否对大豆种子萌发及幼苗生长具有化感作用,以黑航、蒙豆、黑河和汇丰4个大豆品种为受体,研究了不同浓度问荆植株水浸液处理后大豆种子萌发率及幼苗形态指标的变化,从而明晰问荆化感作用对大豆种子萌发及幼苗生长影响的强弱,进一步了解问荆化感物质对作物生长的影响.In order to study whether Equisetum arvense L allelopathic effects on seed germination andseedling growth has an impact, as Heihang, Mengdou, Heihe and Huifeng four Soybean varieties for thereceptor, the effects of different concentrations of aqueous extracts of Equisetum arvense L. plants treated ＋changes in soybean seed germination and seedling morphological index are studied. Based on Equisetumarvense L. allelopathic effects on seed germination and seedling growth of strength, influence on crop growthof Equisetum arvene L. allelopathic is got.
