NOVELTY - Method for preparing vegetable seedling matrix, involves (a) crushing and mixing e.g. seaweed powder and fine soil, processing, and fermenting the mixture, (b) processing e.g. Ephedra to obtain traditional Chinese medicinal liquid, (c) processing plant ash, (d) adding 12% aqueous solution of sodium chloride to e.g. sodium alginate, and immersing the perlite in the solution, (e) immersing the vermiculite in the obtained medicinal liquid, and (f) mixing the products of the steps (a), (d) and (e), and spraying the product of the step (c) to the mixture.    USE - The method is useful for preparing vegetable seedling matrix (claimed).    ADVANTAGE - The substrate is highly nutritious, suitable for seedling root, and simple and convenient to use, and has good water-retaining property.    DETAILED DESCRIPTION - Method for preparing vegetable seedling matrix, involves (a) obtaining seaweed powder, dairy manure, pig manure, straw, corncob powder , perlite, vermiculite, plant ash, Ephedra oil, cinnamon, Chinese honeylocust fruit, rhizoma kaempferiae, sodium alginate, potassium fulvate, naphthylacetic acid, sodium carboxymethyl starch, 12% aqueous solution of sodium chloride and fine soil, crushing and uniformly mixing seaweed powder, dairy manure, pig manure, straw, corncob powder and fine soil, stirring the mixture, controlling water content of the mixture to 57-62%, adding corrosion accelerating agent to the mixture, heating the mixture, immediately performing fermentation of the mixture, eliminating odor, and rapidly killing harmful pathogenic bacteria and eliminating weed seeds during fermentation, (b) cleaning and crushing Ephedra, cinnamon, Chinese honeylocust fruit and rhizoma kaempferiae, adding purified water and immersing the components in purified water for 2-4 hours, extracting the mixture for 3 times by adding water, combining the extracts, heating and concentrating the extract to obtain concentrated juice, adding 95 wt.% ethanol to 10 wt.% concentrated juice, precipitating water-soluble impurities, uniformly dissolving the concentrate, filtering the concentrate using plate and frame filter press and then with micropore filter to obtain filtrate, heating and boiling the filtrate, recycling ethanol, centrifuging the filtrate, and performing UV sterilization to obtain traditional Chinese medicinal liquid, (c) adding 3-5 times water to the plant ash, stirring the mixture, precipitating the mixture, taking out the upper clear liquid, then filtering the mixture to remove residue, and sterilizing the obtained extract, (d) adding 12% aqueous solution of sodium chloride to the sodium alginate, potassium fulvate, naphthylacetic acid and sodium carboxymethyl starch, uniformly stirring the solution, immersing the perlite in the obtained solution for 3-5 days, and obtaining perlite having size of 100-130 meshes, (e) immersing the vermiculite in the traditional Chinese medicinal liquid for 3-5 days, and obtaining the vermiculite having size of 120-150 meshes, and (f) mixing the products obtained in the steps (a), (d) and (e) in a ratio of 8:1:1, mixing and stirring the mixture, and spraying the product obtained in the step (c) to the mixture to obtain product.
