需要努力通过有效使用化肥提高作物产量，以保障全球粮食安全。目前正在开发包封在可生物降解基质中的增强型缓释肥料系统，以解决这一全球性问题。从SRF开发的广泛策略中，我们探索了一种基于植物角质层模型及其作为水和养分运输控制膜的功能的自然灵感解决方案。在这里，小烛树蜡，提取自小烛树野生植物（抗梅毒大戟），研究作为一种可再生的缓释基质的肥料包封通过改进的喷雾冷却过程。从这个过程中，含有40重量%的磷肥的微胶囊获得具有独特的尺寸和化学特性，呈现出缓释行为。考虑到上述特征，讨论了基于植物角质层模型的肥料释放机制的新见解。
Efforts to improve crop yields with efficient use of fertilizers are needed to guarantee global food security. Enhanced slow-release fertilizer systems (SRFs) encapsulated in biodegradable matrices are being developed to address this global concern. From a wide range of strategies for SRFs development, we explored a nature-inspired solution based on the plant cuticle model and its function as a membrane for water and nutrient transport control. Here, Candelilla wax, extracted from Candelilla wild plants (Euphorbia antisyphilitica), is studied as a renewable slow-release matrix for fertilizers encapsulated by a modified spray chilling process. From this process, microencapsulates containing 40 wt% of phosphorus fertilizer are obtained with distinctive sizes and chemical characteristics, presenting a slow-release behavior. Considering the above mentioned features, novel insights into fertilizer release mechanisms based on plant cuticle models are discussed.
