When the height of proliferated cluster buds is 3-4cm, single seedlings are inoculated into the culture medium B to be cultured for 45d to obtain rooted seedlings with strong seedlings and thick roots, and then the rooted seedlings are transplanted. The method is low in cost, short in period and high in test-tube plantlet quality and survival rate, provides technical support for protecting wild resources and breeding high-quality plantlets, and can be used for producing excellent plantlets with consistent genotype backgrounds in a short time.

The invention provides a zinc sulfate impurity removal method. The method comprises the following specific steps: S1, reacting a zinc source with sulfuric acid to generate a crude zinc sulfate solution, filtering, preliminarily removing impurities, and detecting the contents of lead and nickel; s2, heating the zinc sulfate solution, adding a mixed solution of sodium dimethyl dithiocarbamate and thiourea, stirring and filtering to obtain a refined zinc sulfate solution, wherein the mixed solution of sodium dimethyl dithiocarbamate and thiourea is specifically prepared from sodium dimethyl dithiocarbamate, thiourea and water in a weight ratio of 1: (1-3): (2-5); wherein the addition amount of the mixed solution is 10-15 times of the nickel content. By utilizing the synergistic effect of sodium dimethyl dithiocarbamate and thiourea, lead and nickel in zinc sulfate can be removed at the same time, the process is simple, the cost of added reagents is low, industrial operation is easy, and the practical value is high.

The invention provides a tissue culture propagation method for helleborus thibetanus.
