摘要
就目前新型肥料研制过程中所选用的添加材料或包膜材料进行了归类划分,并对高表面活性矿物、高分子聚合物、抑制剂等材料的化学性质、与肥料养分离子相互作用机理等进行了分析和阐述。分析了不同材料对肥料的溶出速率或释放速率的影响,从提高营养元素有效性和生态环境建设方面讨论了这些材料的应用前景。
Selection of amendments is one of the key problems for studying and manufacturing new types of fertilizer such as controlled release fertilizer or slow release fertilizer. This paper introduced the properties and acting mechanisms of different kinds of amendments, such as natural superficial active minerals, humic substances, high molecular polymer and some inhibitors. It also proposes the application prospect of amendments from the viewpoint of nutrient elements availability and ecological environment construction. It may provide theoretical basis for the development of new types of fertilizer.
