摘要:

采用磷酸盐缓冲溶液浸提法和蒸馏水浸提法测定了3种不同类型脲甲醛缓释肥料的冷水不溶性氮和热水不溶性氮的含量,并用F检验和t检验比较两种不同浸提方法的精密度和显著性差异,探讨了不同浸提液浸提对脲甲醛缓释肥料养分释放特性的影响。试验结果表明,采用磷酸盐缓冲溶液浸提法和蒸馏水浸提法测定脲甲醛缓释肥料中冷水不溶性氮和热水不溶性氮含量均可获得较好的精密度,并且两种方法无显著性差异。蒸馏水浸提法便捷、快速,更适合实验室操作。

Abstract:

The phosphate buffer solution extraction method and distilled water extraction method are used to determine the contents of cold water insoluble nitrogen and hot water insoluble nitrogen of three different types of urea-formaldehyde slow-release fertilizers. The precision and significant difference of the two different extraction methods are verified with F test and t test. The effects of different extracts on nutrient release characteristics of urea-formaldehyde slow-release fertilizers are discussed. High precision can be achieved in determination of the contents of cold water insoluble nitrogen and hot water insoluble nitrogen of urea-formaldehyde slow-release fertilizers with both phosphate buffer solution extraction method and distilled water extraction method, and there is no significant difference between the two determination methods; the distilled water extraction method is convenient and fast, and is more suitable for laboratory operation.
