This invention discloses a bamboo charcoal fiber cleaning cloth with antibacterial and antiviral functions and its preparation method, belonging to the field of functional fiber materials technology. The cleaning cloth uses bamboo charcoal fiber as the main body, combined with phosphorylated modified mulberry bark fiber. Zinc ions are used to chelate tea polyphenols and pomegranate peel tannins to form active components, which are then encapsulated in sodium alginate microcapsules and loaded into the porous structure of the fibers. Natural pyrethroid extract and β-cyclodextrin are added to achieve mite prevention and odor suppression. The preparation employs a green process of ultrasonic-assisted chelation and high-voltage electrostatic spray microcapsule preparation. This invention solves the problems of easy loss of antibacterial components and poor mechanical properties in traditional cleaning cloths. After 200 washes, the antibacterial rate remains at 95%-99%, and the tensile strength is 13.5-16.0 CN / dtex. It also has the advantages of being all-natural, residue-free, environmentally friendly, and mass-producible, making it suitable for household and medical cleaning applications.

The invention belongs to the field of agricultural microbial technology and agricultural product safety, and particularly relates to application of a method for preparing a functional biological flora in a targeted biological flora and host original flora coupling mode in rice cultivation. According to the method, bacillus subtilis, bacillus mucilaginosus, brevibacillus laterosporus and host original flora are subjected to coupled symbiotic culture to form specific functional flora, and the specific functional flora is compounded with nutrient carriers such as humic acid potassium fulvate and amino acid chelated trace elements to prepare the targeted biological bacterium water-soluble fertilizer. The microbial agent effectively reduces the bioavailability of heavy metals such as cadmium, lead and arsenic in soil and migration of the heavy metals to rice; meanwhile, the functional flora secretes hydrolase, oxidoreductase and the like, degrades pesticide residues such as organophosphorus and pyrethroid and decomposes the pesticide residues into non-toxic or low-toxicity substances, the method is specially used for solving the problem that heavy metal and pesticide residues in the rice in the filling stage of the rice exceed the standard, and the quality and edible safety of the rice are guaranteed from the source.
