摘　　要：通过缓控释肥养分释放试验,研究了缓控释肥标准检测方法与快速测定方法的差异。结果表明:供试CRF1至CRF4样品快速测定方法与标准方法误差范围为2.7%～8.3%,完全满足GB/T 23348—2009养分释放期允许误差范围25%的要求;在改变包膜材料、添加剂和喷涂温度条件下,制成的CRF5至CRF16样品采用快速测定方法用原有预测方程预测养分释放期可靠性差,表明一个预测方程不能快速准确评价所有缓控释肥。Based on nutrient release testing method for quality detection experiment, the difference between of slow/controlled release fertilizers standard testing method and rapid is studied. The results show that error range between rapid method and standard method is from 2.7% to 8.3% for CRF1, CRF2, CRF3 and CRF4, which completely meet the demand of national standard of GB/T 23348--2009 about error range （25%）; For the products （CRF5 to CRF16） with the production conditions changed such as envelope materials, additives and spraying temperature, the evaluation of slow/controlled release fertilizers is not reliable with the original prediction equation; So one prediction equation can＇t be used to rapidly and accurately detect every slow/controlled release fertilizer.
