Culture medium and preparation method thereof

The invention discloses a culture medium and a preparation method thereof. The culture medium is mainly composed of the following raw materials in percentage by volume: 50%-60% of artificial peat, 20%-30% of coco coir, 20%-30% of fermented chaff and 0-10% of perlite, wherein the artificial peat is mainly prepared from reed residues, rapeseed dregs, calcium magnesium phosphate, urea and an organicmaterial decomposition agent. The preparation method comprises a step of uniformly mixing the raw materials to prepare the culture medium. The culture medium is rich in nutrition, stable in physicochemical property and high in economic value, replaces natural peat with the artificial peat serving as a raw material, has very high commercial value and cost advantages, belongs to renewable resources,and very meets the development requirement of the culture medium. 本发明公开了一种栽培基质及其制备方法，该栽培基质主要由以下体积分数的原料组成：人造泥炭50％～60％，椰糠20％～30％，发酵谷壳20％～30％和珍珠岩0～10％，其中人造泥炭主要由芦苇渣、菜枯、钙镁磷、尿素和有机物料腐熟剂制成。制备方法为将各原料混合均匀制得栽培基质。本发明的栽培基质营养丰富、理化性质稳定、经济价值
