本研究是通过为土壤微生物提供大量的新鲜有机能源物质，激发土壤微生物快速繁殖。微生物在繁殖过程中降解有机能源物质转化难溶性磷，保护有效磷，使土壤中有效磷含量得以提高。
This study is to stimulate the rapid propagation of soil microorganisms by providing a large number of fresh organic energy materials for soil microorganisms. Microbial degradation of organic matter in the process of transformation of insoluble phosphorus, phosphorus protection, so that the effective phosphorus content in the soil can be increased.
