摘　　要：基于农田土壤磷素累积的持续性及普遍性,土壤磷活化剂的应用成为作物生产减磷增效的关键措施。从土壤磷素的形态及主要转化过程、土壤磷活化剂(低分子量有机酸、高分子量有机酸、磷酸酶及其激活剂、微生物菌肥、复杂有机质、高表面积与高表面活性物质以及其他类物质)在农业中的应用研究及在马铃薯生产上的应用潜力3个方面进行了综述,以期为马铃薯磷肥减施增效提供参考。Based on the persistence and universality of phosphorus accumulation in farmland soil, the application of soil phosphorus activator has become a key measure to reduce phosphorus and increase efficiency in crop production.The form and main transformation process of soil phosphorus, soil phosphorus activator, including low molecular weight organic acids, high molecular weight organic acids, phosphatase and its activation agent, microbial fertilizer, complex organic matter, high surface area and high surface active substance and other substances, in agricultural researches, and its application potential in potato production were reviewed, which may provide a reference for reducing the application of potato phosphorus fertilizer and increasing efficiency.
