Preparation method for synthesizing nanometer material by plant extracting liquid

The invention discloses a preparation method for synthesizing a nanometer material by plant extracting liquid. In the steps of the preparation method for synthesizing the nanometer material by the plant extracting liquid, processing is conducted through equipment in each step, so that the working efficiency is improved and the labor intensity of personnel is reduced; furthermore, processing preparation is conducted through equipment, so that unnecessary personnel cost is reduced; through the whole flow line preparation, preparation production is more efficient, so that the requirement of large-scale production preparation can be met well; a reducing solution is prepared from folium artemisiae argyi, chrysanthemum, cape jasmine, eucommia ulmoides, ginkgo leaves, clove, plantain herb and mint leaves, so that the reducing solution can react with ferric nitrate; furthermore, compared with the reducing solution prepared from the plants such as clove, dogwood, sanguisorba officinalis and smoked plum, the reducing s
