摘  要：
通过三室隔网分室盆栽模拟试验,研究了分室不同磷(P)源[无机磷(磷酸二氢钾)和有机磷(大豆卵磷脂),P添加量均为50 mg·kg-1]添加和根室接种不同丛枝菌根真菌(AMF)[Glomus mosseae(GM)、Glomus etunicatum(GE)]对间作玉米种植红壤无机磷形态的影响。结果表明:无论接种与否,间作处理使根室土壤有效磷含量显著降低,说明间作能够促进玉米植株对土壤有效磷的吸收,且有效磷的耗竭从根际土壤开始。除OP50-单作玉米处理的Org-P外,接种AMF均一定程度增加了各形态无机磷含量。此外,根室土壤有效磷的主要组分为Ca2-P、Al-P和Org-P,其中Org-P与土壤有效磷有着极显著的负相关关系。

摘  要：
A pot simulation experiment was conducted to study the phosphorus( P) forms in red soil under different P sources [inorganic phosphorus( potassium dihydrogen phosphate) and organic phosphorus( soy lecithin) ]addition to compartment chamber( P 50 mg · kg- 1soil respectively) and two different kinds of arbuscular mycorrhizal fungi( AMF),i. e. Glomus mosseae( GM) and Glomus etunicatum( GE),inoculation for intercropping maize planting condition. The research results showed that regardless of the inoculation of AMF,intercropping treatment significantly decreased the available P content in soil of root chamber,which indicated that intercropping promoted the absorption of available P by maize plants from soil,and the available P exhaust began from the rhizosphere soil. Except the Org-P under OP50 addition and monomaize treatment,AMF inoculation increased the contents of all inorganic P forms to a certain extent. Ca2-P,Al-P and Org-P were the main group of soil available P in the soil of root chamber,and the Org-P was significantly negative correlated with available P in red soil.
