摘要
概述了缓/控释肥养分释放特性的评价方法。多数研究方法都属实验室快速测定法,适用于生产过程产品检验。各方法结果都能比较出产品的养分释放速率,但与实际尚有距离。生物评价法虽贴近实际,但过程太长。
Methods are summarized for the assessment of nutrient release characteristics of slow-/ controlled-release fertilizers. Most study methods are rapid determination ones for the laboratory, applicable to product inspection in the production process. The results from these methods can be used to compare their nutrient release rates but are somewhat different from the actual values. The biological assessment method shows its result approaching the actual value, but its process is too long.
