摘要
以硫脲、异丁醛和磷酸二氢钾为原料制备了一种新型多营养缓释化肥(MNSRF),并通过红外吸收光谱(FTIR)、核磁共振波谱(1H-NMR、13C-NMR、31P-NMR)对其结构进行了表征。研究了反应温度、反应时间等工艺条件对MNSRF缓释性能的影响。通过静水释放试验研究了MNSRF中氮、硫、磷和钾等多种营养元素的养分释放特性,实验结果表明,MNSRF具有很好的缓释性能。
The novel slow release fertilizer containing multiple nutrient elements (MNSRF) is synthesized with thiourea and isobutyraldehyde as raw materials. The structure of MNSRF is characterized by infrared absorption spectrum (FTIR) and nuclear magnetic resonance spectroscopy ( 1H-NMR, 13 C-NMR, 31 P-NMR ). The effects of reaction temperature and reaction time on the slow-release performance of MNSRF are studied. The nutrient element release properties are investigated through hydrostatic releasing test. The results confirm the good slow release performance of MNSRF.
