NOVELTY - An environmentally-friendly full-nutrition organic culture medium comprises 63-75 wt.% peat having humic acid content of more than 20%, 3-5 wt.% expanded vermiculite particles, 3-5 wt.% eggshell powder, 3-5 wt.% kelp powder, 3-5 wt.% medical stone powder, 1 wt.% zinc sulfate, 0.5 wt.% boron sand, 0.5 wt.% ammonium molybdate, 1 wt.% copper, 2 wt.% ferric EDTA, 2-3 wt.% selenium-rich mineral mud of 60-80 mesh, 2-3 wt.% rare-earth mineral mud of 60-80 mesh, 2-3 wt.% lava particles having a particle size of 3-15 mm, and 2-3 wt.% expandable ceramic aggregate.    USE - Environmentally-friendly full-nutrition organic culture medium is used in ecological cultivation, soil improvement, and domestic gardening.    ADVANTAGE - The environmentally-friendly full-nutrition organic culture medium is safe, and can be prepared industrially by a simple and easy method.    DETAILED DESCRIPTION - An environmentally-friendly full-nutrition organic culture medium comprises 63-75 wt.% peat having humic acid content of more than 20%, 3-5 wt.% expanded vermiculite particles, 3-5 wt.% eggshell powder of 40-60 mesh, 3-5 wt.% kelp powder of 40 mesh, 3-5 wt.% medical stone powder of 60-80 mesh, 1 wt.% zinc sulfate, 0.5 wt.% boron sand, 0.5 wt.% ammonium molybdate, 1 wt.% copper, 2 wt.% ferric EDTA, 2-3 wt.% selenium-rich mineral mud of 60-80 mesh, 2-3 wt.% rare-earth mineral mud of 60-80 mesh, 2-3 wt.% lava particles having a particle size of 3-15 mm, and 2-3 wt.% expandable ceramic aggregate. An INDEPENDENT CLAIM is included for preparation of organic culture medium, which involves adding 5 kg EDTA and ethylenediamine solid powder as chelating agent per ton of peat and mixing and stacking for 7 days to improve humic acid content, mixing all raw materials, stacking for 7 days for aging, maintaining water content of material at 40-50% by humidity detection, placing the material on upper conveyor belt, passing through a high-temperature steam sterilizing groove at 80-95 degrees C, adding 10 l bean fermentation liquid per ton of material to improve content of amino acid and nucleotide, supplying and recovering beneficial microorganisms, drying in a furnace at 60-80 degrees C to a water content of 30%, and packaging.
