The invention relates to a method for synergistically enhancing bank slope vegetation water quality purification through arbuscular mycorrhiza and nitrifying bacteria, and belongs to the technical field of water environment ecological management and ecological engineering. The method comprises the following three core steps: preparation of an arbuscular mycorrhiza-nitrifying bacteria immobilized complex microbial inoculant, construction of a bank slope vegetation rhizosphere microhabitat, and cooperative regulation and control of system stabilization and purification functions. According to the method, the rhizosphere microhabitat of the bank slope vegetation is actively intervened by artificially inoculating the fungicide formed by the arbuscular mycorrhiza and the nitrifying bacterium community, and the symbiotic system formed by the arbuscular mycorrhiza-nitrifying bacterium composite community and the plants is utilized, so that the method is environment-friendly, high in cost benefit, simple and stable in operation condition, easy to engineer and suitable for large-scale popularization and application. And an innovative solution is provided for realizing synergistic interaction of bank slope ecological restoration and water quality purification.

This invention discloses a method for improving soil in potato cultivation, belonging to the field of agricultural soil remediation technology. Addressing the problems of soil acidification, compaction, reduced beneficial microorganisms, and severe soil-borne diseases caused by continuous potato cropping, this invention provides a synergistic improvement method integrating soil pretreatment, coupled application of microbial agents and organic fertilizers as basal fertilizers, dynamic and precise regulation throughout the growth cycle, coordinated water and fertilizer management, and post-harvest remediation. This method involves basal application of a specific ratio of compound microbial agents coupled with organic fertilizers. Based on the physiological needs and disease occurrence patterns of potatoes at different growth stages, and combined with the dynamic and precise regulation of the timing and dosage of microbial agent application through a drip irrigation system, water and fertilizer supply are simultaneously optimized, achieving synergistic effects of biological antagonism, soil ecological restoration, and crop nutrient regulation. This invention effectively improves the soil micro-ecological environment, reduces the incidence of soil-borne diseases, reduces reliance on chemical fertilizers and pesticides, and improves potato yield and quality.

This invention discloses a biofilter packing material for VOCs organic waste gas treatment and its preparation method, belonging to the technical field of biofilter packing materials. The biofilter packing material for VOCs organic waste gas treatment of this invention includes a nutrient slow-release core, a conductive functional shell layer, and a surface functionalized layer. The dry weight percentages of the raw materials for the nutrient slow-release core, conductive functional shell layer, and surface functionalized layer are 50%-60%, 35%-45%, and 3%-5%, respectively. The biofilter packing material for VOCs organic waste gas treatment and its preparation method proposed in this invention adopt a three-layer composite structure of a nutrient slow-release core, a conductive functional shell layer, and a surface functionalized layer. The core is responsible for the long-term supply of nutrients and carbon sources; the shell layer achieves efficient adsorption, conductive transfer, and microenvironment regulation; and the surface layer ensures the rapid colonization and targeted degradation of functional microorganisms. This spatial functional partitioning avoids mutual interference between different components and greatly improves the overall performance of the packing material.

The invention belongs to the crossing field of environmental functional materials and microbial technologies, and particularly relates to an LDHs-biological membrane solid-liquid interface culture method which comprises the following steps: S1, preparing an LDHs material; s2, constructing a standardized LDHs mineral membrane; s3, carrying out sterile treatment on the LDHs mineral membrane; and S4, carrying out solid-liquid interface culture on the LDHs-biological membrane. According to the method, the forming ability, metabolic activity, structural stability and pollutant removal characteristics of the LDHs material surface biological membrane can be effectively evaluated, and accurate and reliable evaluation is provided for deep exploration of a material-biological membrane interaction mechanism and promotion of application of the material-biological membrane interaction mechanism in environmental restoration.
