The variations of rhizosphere soil arbuscular mycorrhizal fungi (AMF) and their impact mechanism are still unclear under different intercropping systems in the Yellow River Irrigation District of Ningxia, China. A field experiment to study variations in rhizosphere soil AMF diversity and its effects under different planting systems in this area. Three intercropping systems consisting of six rows of spring wheat intercropped with two rows of soybean (RSW), wheat monoculture (RW), and soybean monoculture (RS) were applied. The results showed that the RSW treatment has a 5.6% and 10.0% higher soil organic carbon (SOC) content than the RW and RS plots, respectively. The dominant genera in this study are Glomus and Paraglomus. The Shannon index, Simpson index, Chao1 value, and abundance-based coverage estimator in the RSW treatment are higher than in the RS plots. Additionally, the multiple linear regression equation suggests that invertase activity is the main impact factor for the Shannon index of AMF. Moreover, the wheat yield in the RSW plot is 11.4% higher than the RW plot. The results suggest that the RSW treatment has great potential for improving soil nutrients, AMF diversity, and wheat yield to sustain soil health and crop production.

大豆间作对麦田根际土壤丛枝菌根真菌群落多样性的影响
宁夏黄河灌区不同间作制度下根际土壤丛枝菌根真菌（AMF）的变化及其影响机制尚不清楚。田间试验研究了该地区不同种植制度下根际土壤AMF多样性及其影响。应用了由六行春小麦与两行大豆（RSW）、小麦单作（RW）和大豆单作（RS）组成的三种间作系统。结果表明，RSW 处理的土壤有机碳（SOC）含量分别比 RW 和 RS 地块高 5.6% 和 10.0%。本研究的优势属是Glomus和Paraglomus。Shannon 指数、Simpson 指数、Chao1 值、RSW 处理中基于丰度的覆盖率估计值高于 RS 图。此外，多元线性回归方程表明，蔗糖酶活性是 AMF 香农指数的主要影响因素。此外，RSW 地块的小麦产量比 RW 地块高 11.4%。结果表明，RSW 处理在改善土壤养分、AMF 多样性和小麦产量以维持土壤健康和作物生产方面具有巨大潜力。
