摘要: 以枸树和盐肤木为材料，通过盆栽试验分别接种摩西菌根(A)、根内球囊霉(B)、幼套球囊霉(C)、混合菌剂(AB、AC、BC、ABC)对枸树和盐肤木的生长生理特性的影响。结果表明，单菌剂A对构树的侵染率最高，其平均侵染率为79.11%。单菌剂C对盐肤木的侵染率最高，其平均侵染率为81.67%。7种菌剂均能增加盐肤木的地上部干质量，促进效应呈现A > B > ABC > C > AC > BC > AB趋势。混合剂菌剂ABC处理组中的构树的Pn、Gs、Tr和Ci是7种AMF处理组中最大的。本研究初步证实了混合菌剂ABC适合应用于构树种植，同时筛选出单菌剂A和C是适合盐肤木的优良菌种。AMF-植物共生体技术在筛选边坡植物生态修复方面具有良好的应用前景。
Abstract: An experiment was conducted to analyze the effects of arbuscular mycorrhizal fungi (AMF) on the growth and physiology of slope plant species (Broussonetia papyrifera and Rhus chinensis Mill.) under greenhouse conditions. Slope plant species were inoculated with Glomus mosseae (A), Glomus intraradices (B), Glomus etunicatum (C) and mixed AMFs (AB, AC, BC, ABC), and the AMF-infection rate, biomass, photosynthetic parameters were studied. The results showed that the highest AMF-infection rate was the Glomus mosseae-Broussonetia papyrifera symbiont (A) and Glomus etunicatum-Rhus chinensis Mill. symbiont (C), which average AMF-infection rate reached 79.11% and 81.67%. It also proved that these seven AMFs could enhance the underground biomass of Rhus chinensis Mill. The photosynthetic efficiency results showed that AMFs (ABC)-Rhus chinensis Mill. symbiont was the best. Thus, the AMF-plant symbiont technology has good application prospects in the slope plant species screening for ecological restoration.
