利用膜对水溶性氮肥进行包裹，可以控制养分的释放，最大限度地提高施肥效果，减少环境污染。以食品级微晶蜡（MW）和海洋多糖衍生物（海藻酸钙和壳聚糖-戊二醛共聚物）为原料，制备了一种新型双层包膜控释肥料（CRF）。以海洋多糖衍生物和MW为包膜剂，对水溶性氮肥颗粒进行包膜处理。采用一种简便、环保的方法制备CRF。采用扫描电子显微镜（SEM）和傅里叶变换红外光谱（FTIR）对产物的形貌和组成进行了表征。采用紫外-可见分光光度法测定了其在水中的释氮性能。海藻酸钠和海洋多糖衍生物包覆后，肥料的控释性能得到显著改善。结果表明，双层包膜控释肥能够实现控释，具有良好的控释性能，符合欧洲控释肥标准。
Encapsulation of water-soluble nitrogen fertilizers by membranes can be used to control the release of nutrients to maximize the fertilization effect and reduce environmental pollution. In this research, we formulated a new double-coated controlled-release fertilizer (CRF) by using food-grade microcrystalline wax (MW) and marine polysaccharide derivatives (calcium alginate and chitosan-glutaraldehyde copolymer). The pellets of water-soluble nitrogen fertilizer were coated with the marine polysaccharide derivatives and MW. A convenient and eco-friendly method was used to prepare the CRF. Scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) were used to characterize the morphology and composition of the products. The nitrogen-release properties were determined in water using UV-Vis spectrophotometry. The controlled-release properties of the fertilizer were improved dramatically after coating with MW and the marine polysaccharide derivatives. The results show that the double-coated CRFs can release nitrogen in a controlled manner, have excellent controlled-release features, and meet the European Standard for CRFs.
