The invention belongs to the technical field of bamboo old making, and particularly relates to an antiquing bamboo preparing method. Ten days ago before bamboo
cutting, a sunshade net with the sunshade rate being 75%-85% is arranged above the bamboo,
brush application of an infection
bacteria solution is conducted on the surface of the bamboo at random,
cutting is conducted, and the original bamboo is polished after being sterilized and cleaned; two-time coloring is sequentially conducted on the surface of the bamboo after
polishing, color wiping and color homogenizing treatment is conducted after completion, and after completion, the antiquing bamboo is obtained through
drying; and the infection
bacteria solution is a stereostratum cor-ticioides infection
bacteria solution. Compared withthe prior art, the antiquing bamboo preparing method has the following beneficial effects that the stereostratum cor-ticioides infection bacteria solution is used for treating the to-be-
cut bamboo under the shading condition, irregular damage can be formed on the surface of the bamboo while the tenacity of the bamboo cannot be influenced, meanwhile, the defect that dye molecules are not prone to
permeation can be overcome, the bamboo old making antiquing effect is natural and attractive in cooperation with two-time coloring and later treatment, and the color fixing effect is good; and the artistic effect is achieved, and usage and popularization can be achieved.
