The soil water storage, growth development, biomass and yield in maize/soybean intercropping system under different separation methods were measured to analyze the resource competition of the intercropping crops. The treatments included no shoot or root separation (T1), shoot and root separation (T2), only root separation (T3), and only shoot separation (T4). Results indicated that compared to others, the average soil moisture content in the 0-120 cm soil layer decreased by 3.1%-12.9% in maize line, and by 2.8%-12.5% in soybean line for T1. Compared to T1, maize growth stage in T2, T3 and T4 came late, and the plant height, leaf area and cumulative total biomass, yield and yield components all decreased, while the trends found for soybean were the opposite. In summary, the changes of crop growth and yield in the maize/soybean intercropping system were driven by the interactions of above- and below-ground parts, and the below-ground part played a more important role.
测定了不同分隔方式下玉米/大豆间作系统的土壤贮水量、作物生长发育、生物量及产量，以分析间作作物的资源竞争情况。处理包括地上部和地下部均不分隔（T1）、地上部与地下部分隔（T2）、仅地下部分隔（T3）和仅地上部分隔（T4）。结果表明，与其他处理相比，T1处理下玉米行0-120 cm土层平均土壤含水量降低了3.1%-12.9%，大豆行降低了2.8%-12.5%。与T1相比，T2、T3和T4处理下玉米生育期延迟，株高、叶面积、累积总生物量、产量及产量构成因素均降低，而大豆的趋势则相反。综上所述，玉米/大豆间作系统中作物生长和产量的变化是由地上部和地下部的相互作用驱动的，且地下部起更重要的作用。
