摘要:
以脲醛-半水石膏-膨润土新型的有机无机复合缓释材料作为粘结剂，依据大豆的生长需求，采用挤压混合反应振动筛分圆盘造粒一体化制备技术，制备出4种低甲醛脲醛石膏膨润土基大豆专用的缓释肥料，即缓释氮肥、包膜缓释氮肥、缓释复合肥和包膜缓释肥；采用石英砂连续淋溶法测定缓释肥的养分释放速率，并与常规肥料进行对比，评价大豆缓释肥料N、P、K、S元素的养分释放特性。结果表明：相比常规肥料，大豆缓释肥的养分释放速率缓慢、周期长、缓释性能好，其中包膜缓释肥的缓释性能最好。
Abstract:
The aim of the study was to prepare soybean specific slow-elease fertilizers for soybean with the low formaldehyde urea-formaldehyde-gypsum-bentonite as the organicinorganic binder by an integral preparation technology of extrusion mixing reaction,vibration screener and disc granulation,and nutrients release characteristics were determined by the method of continuous leaching in quartz sand and compared with an conventional fertilizer to evaluate the release characteristics of N,P,K and S in soybeans slow release fertilizers.The results showed that nutrients release of slowrelease fertilizers prepared were slower and longer and release characteristics of the coated slow release fertilizers was the best.
