英文摘要A plot experiment was conducted to monitor the effects of dual-inoculation of efficient Sesbania rhizobia and arbuscular mycorrhizal fungi on the salt reducing effect and soil nutrition in moderate saline-alkali soil of the Yellow River Delta hinterland to explore the application prospects for microbe-plant associations during saline- alkali soil rehabilitation. The results showed that the up-ground biomass increased by 28.6% and below-ground biomass increased 51.3% in dual-inoculating planted soil > Sesbania planted soil > unplanted soil. The soil salt content of Sesbania planted soil was maintained at 0.9-2.0, which was 67%-79% lower compared to unplanted soil. The salt content in dual inoculating planted soil was 20%-25% lower than that in planted soil. The dual inoculation treatment increased available nitrogen, phosphorus, and potassium in soil greater than the Sesbania planted soil. These results indicate that dual-inoculation of efficient Sesbania rhizobia and arbuscular mycorrhizal fungi improved the ability of green manure crops to fertilize and rehabilitate saline-alkali soil.
中文摘要为了治理黄河三角洲土地盐碱化问题,在山东省东营市垦利县永安镇(37.56°N, 118.74°E)选取一块面积为70 m2的土地作为试验地,进行根瘤菌和丛枝菌根真菌接种田菁(Sesbania cannabina)进行降盐试验。试验设置3个处理,分别为对照组(不种植田菁)、不接种组、双接种组(根瘤菌和丛枝菌根真菌接种田菁)。监测高效根瘤菌和丛枝菌根真菌接种田菁对田菁降盐效果及对土壤营养元素的影响。结果显示,田菁质量和叶绿素含量等长势指标,双接种组>不接种组>对照组,双接种组田菁植株的地上部干物质质量比不接种组增加了26.12%,地下部干物质质量增加了46.15%。不接种组田菁使土壤含盐量控制在0.9~2.0,与对照组相比土壤含盐量降低了67%~79%。与不接种组田菁相比,双接种处理土壤含盐量降低了20%~25%。此外,双接种组土壤中速效氮、磷、钾含量比不接种组土壤明显增加。综上,接种高效田菁根瘤菌和丛枝菌根真菌能有效提高田菁的降盐和肥田能力,为治理黄河三角洲土地盐碱化问题提供技术参考。
