The invention relates to a pinellia ternate tissue culture one-step speciation method. Pinellia ternate tissue culture seedlings, that are obtained from a one-step seedling and can be treated with hardening and transplanting, are injected with liquid medium without switch, and cultured sequentially at 25+- 2 DEG C, with a photoperiodicity of 12h/d and an illumination intensity of 1000-1500Lx. Pinellia ternates complete one growth period in a culture bottle, and are washed out from the medium to be transplanted. The invention is characterized in that the method simplifies hardening seedling steps, avoids problem of transplanting survival rate, and lowers the possibility of re-infection of virus in pinellia ternate first generation production. In addition, the method combines all merits of the one-step speciation method, so that pinellia ternate plants have good inductivity, differentiation rate, and number of tubers differentiated from each explant.

The invention discloses a dressing containing composite antibacterial microspheres. The dressing has the advantages of safe, broad-spectrum antibacterial, long-acting antibacterial, anti-inflammatoryand anti-swelling.
