摘　　要：[目的]研究不同套种作物对宽叶羌活生长的影响,为羌活栽培技术的研究提供科学依据。[方法]分别将羌活与蚕豆套种、羌活与小麦套种、羌活与油菜套种,并观察不同套种田羌活根部性状、叶部性状及生物量性状;测定试验地土壤中各养分含量的变化。[结果]蚕豆、小麦、油菜对套种羌活的基本苗、出叶数、侧根数没有显著影响;蚕豆茬口促进羌活根、叶片、茎的生长及生物量的增加作用明显高于小麦田和油菜田的促进作用;蚕豆、小麦、油菜茬口的全氮、全磷、全钾、有机质和pH值在生长季变化较小,速效养分普遍下降,其中,蚕豆茬下降明显,尤以速效氮下降最明显。[结论]小麦茬口有利于促进羌活根的生长,蚕豆茬口有利于促进羌活叶的生长。[ Objective ] The aim was to study the effect of different inter-planting crops on growth of Notopterygium forbesii de Boiss, and provide some scientific basis for the research of cultivating technique of N. forbesii de Boiss. [ Method] N. forbesii de Boiss was inter-planted with broad bean, wheat and rape. The root, leaf and biomass characteristics of N. forbesii de Boiss were observed in different inter-planting fields, the change of nutrient content in the tested soil was determined. [ Result] There were no significant effects on basic seedling, leaf number, lateral root number of the inter-planting N. forbesii de Boiss to broad bean, wheat and rape. The broad bean for rotation increased dramatically in root, leaf, stem growth and biomass of the N. forbesii de Boiss than the wheat and rape fields. Total N, total P, total K, organic matter and pH value were less variation with growth season, available nutrient was falling throughout, among the broad bean for rotation decreased dramatically, specially, available N was the greatest reduction. [ Conclusion] The wheat for rotation made for growth of the N. forbesii de Boiss root, the broad bean for rotation made for growth of the N. forbesii de Boiss leaves.
