英文摘要	A rhizobox experiment was conducted to investigate the effects of phosphorus (P) sources on the rhizosphere soil characteristics of two wheat genotypes Xiaoyan54 (P-efficient) and Jing411 (P-inefficient), which were colonized with an arbuscular mycorrhizal fungus and grown in Cumulic Haplustoll. The four P sources included a control (no added P), OP [organic P: sodium (Na)-phytate], IP [inorganic P: monopotassium phosphate (KH2PO4)], and OPIP (Na-phytate plus KH2PO4). The results showed that when no exogenous P was added the shoot biomass of Xiaoyan54 was 28% significantly higher than Jing 411. The acid phosphatase activity (APA) in the rhizosphere soil was significantly depressed when inorganic P was added; the APA for Xiaoyan54 was higher than that of Jing411 in most of the layers regardless of the P source. Inorganic and organic P fertilizer conditions did not significantly impact the soil pH relative to the control, and the pH did not significantly differ between the two genotypes. In conclusion, when no exogenous P was added, shoot biomass of Xiaoyan54 was greater than Jing411. This increase was promoted by greater soil APA but not soil acidification. The rhizosphere soil pH was not altered across different wheat genotypes or P sources, but APA was increased in the soil of control and OP-treated plants compared with IP- and OPIP-treated plants. The APA of Xiaoyan54 was higher than Jing411 for all of the P sources. The response mechanism of rhizosphere soil acidification is different from acid phosphatase exudation in plants receiving different P sources under arbuscular mycorrhizal fungus inoculation.
