摘要/Abstract

摘要： 以晋西黄土区核桃大豆间作系统为研究对象，采用分层挖掘法对核桃-大豆间作系统细根分布特征及地下竞争状况进行研究，旨在为该地区果农间作系统的高效可持续经营提供科学依据。结果表明：核桃细根在垂直方向上主要分布在0～40 cm土层内，水平方向上55.7%的细根集中分布在距树行0.5～1.5 m区域中；间作物大豆的根系在垂直方向上集中分布在0～20 cm土层内，水平方向上根干重随距树行距离的增加呈增加趋势；在水平方向上距树行1.0～2.5 m的区域是核桃和大豆地下种间竞争主要发生区，其中以1.5～2.0 m区域的竞争最为剧烈。

Abstract: The method of stratified digging was adopted to study the fine root distribution and underground competition in a walnut-soybean intercropping system in Loess Plateau of western Shanxi, Northwest China, aimed to provide scientific support for the efficient and sustainable management of fruit tree-crop intercropping system in this region. The walnut fine roots in the intercropping system were concentrated in 0-40 cm soil layer, and 55.7% of the roots were mainly distributed within the areas 0.5-1.5 m from walnut tree. Soybean fine roots were mainly distributed in 0-20 cm soil layer, and presented an increasing trend with the increasing distance from walnut tree. The underground interspecies competition between walnut and soybean mainly occurred within the areas 1.0-2.5 m from walnut tree, and was most intense within the areas 1.5-2.0 m from the tree.

Key words: straw amendment, C/N, soil CO₂ emission, black soil, soil carbon sequestration.
