Preparation method and application of biomass plant fruit nucleic acid disinfectant

The invention provides a preparation method and application of a biomass plant fruit nucleic acid disinfectant. The method comprises the following steps: preparing a plant fruit nucleic acid extract stock solution; 10-20 g of cortex mori radicis, 5-10 g of flos lonicerae, 5-15 g of fructus forsythiae, 5-15 g of radix scutellariae, 5-15 g of folium artemisiae argyi, 5-15 g of cortex phellodendri and 5-10 g of fennel are adopted as raw materials to prepare a traditional Chinese Adding 25-40g of the plant fruit nucleic acid extract stock solution prepared in the step S1 into the traditional Chinese medicine water extract obtained in the step S2, heating and stirring at normal temperature, then adding deionized water to adjust the pH value to 2-4, and then performing membrane filtration treatment to obtain the biomass plant fruit nucleic acid disinfectant. The prepared biomass plant fruit nucleic acid disinfectant has a remarkable inactivation effect on viruses, fungi and bacteria, is safe and stable, and has a w
