The invention discloses a wood
chip dyeing method and its application. The wood
chip is cleaned with clear water to remove surface
dirt and floating dust; then placed in a
hydrogen peroxide solution with a concentration of 8-12%, and soaked for 12-24 hours , and finally washed with water to remove residual
hydrogen peroxide; soak 100g of Coptidis root in 1L of water for 1 to 2 hours, add 10L of water to boil for 1.5 to 2.5 hours to obtain a dark brown yellow
berberine dye solution; The broken wood chips are placed in the obtained
berberine dye solution for 16-24 hours of dip-
dyeing treatment, taken out, rinsed, and dried to obtain golden yellow broken wood chips. Using the
berberine dye solution to dye the broken wood chips into golden yellow is safe,
pollution-free, simple and easy, and low in cost. Laying it around the planted plants can not only keep the soil moist, increase
soil fertility, and promote tree growth, but also beautify the environment, increase
visual experience, and improve its ornamental value.
