Method for rapidly cultivating biological crust, improving soil quality and promoting plant growth

The invention relates to the field of algae biology, in particular to a method for rapidly cultivating biological crust, improving soil quality and promoting plant growth. Comprising the following step: applying one or more of diatom, chlorella, bacillus megatherium and potassium polyacrylate into soil. According to the method for rapidly cultivating the biological crust, improving soil quality and promoting plant growth, diatom, chlorella and bacillus megatherium are prepared according to different proportions, the biological crust is formed after the diatom, the chlorella and the bacillus megatherium are applied into the soil, the high water-retaining property of potassium polyacrylate is combined, long-acting keeping of the crust is promoted, the quality of soil below the crust is improved, and the plant growth is promoted. The plant growth is promoted. 本发明涉及藻类生物学领域，特别是涉及一种生物结皮快速培育提高土壤质量促进植物生长的方法。包括以下步骤：将硅藻、小球藻、巨大芽孢杆菌和聚丙烯酸钾盐中的一种或多种施用到土壤中。本发明提供了一种生物结皮快速培育提高土壤质量促进植物生长的方法，本发明通过配置硅藻、小球藻、巨大芽孢杆菌的不同配比，施入土壤后形成生物结皮
