This invention discloses *Aphelenchus brittleus* and its applications, relating to the field of microbial technology. The strain is taxonomically named *Aphelenchus brittleus* (…). Acaulospora delicata The specimen, with accession number CGMCC NO.42100, is a *C. cristatum* NM26B that can improve the yield and quality of chives, enhance mineral nutrient absorption, and increase the expression of genes synthesizing chive-specific aroma compounds. This lays the foundation for future research and development of suitable microbial agents for the development of the chive industry.

This invention discloses a method for removing nitrates from wastewater generated during drill-and-blast tunnel construction, comprising the following steps: 1. Preparation of electrospun nanofibers: First, DMF is added to a container, and submicron-sized iron powder and submicron-sized calcium-based montmorillonite are added sequentially to the DMF solution and ultrasonically dispersed. Then, the mixture is stirred to ensure uniform dispersion of the iron powder and calcium-based montmorillonite. PAN powder is weighed and added to the above solution, and stirred until the PAN is completely dissolved into a viscous liquid. The resulting solution is then placed in an electrospinning machine for electrospinning to prepare PAN nanofibers. 2. Removal of nitrates from the drill-and-blast tunnel construction wastewater: The prepared PAN nanofibers are completely immersed in the drill-and-blast tunnel construction wastewater. After immersion for a period of time, the PAN nanofibers are removed. This invention can efficiently and cost-effectively remove nitrates present in wastewater generated during drill-and-blast tunnel construction.

The invention belongs to the field of soil pollution treatment, and relates to a method for jointly relieving toxicity of microplastics to a soil-plant system based on a nitrification inhibitor-carbon nanomaterial. The method comprises the following steps: applying a nitrification inhibitor and a carbon nanomaterial to plant planting soil; the nitrification inhibitor is DMPP, and the carbon nanomaterial is one or more of a multi-walled carbon nanotube and a nanodiamond. The method can technically slow down microplastic pollution, improve soil health and guarantee quality safety of agricultural products.
