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.
