Abstract：
Sustainable agriculture initiatives are needed to ensure the food security of the people all over the world. Soilless cultivation methods using hydrogels may give a revolutionary response as well as a more ecological and productive alternative to conventional farming. This study attempted extraction of pectin from the rind of albedo yellow passion fruit (Passiflora edulis var. flavicarpa Degener)and hydrogels from pectin and activated carbon was compared with pure pectin hydrogel; Pectin- Activated Carbon hydrogels (PAC) showed a microporous structure with excellent hydrophilicity and showed superior water holding capacity. Then the prepared hydrogels were examined with various instrumental techniques like FTIR, SEM, XRD, Raman, BET and rheological properties. In the BET analysis, PAC3 shows the highest surface area of 28.771 m2/g when compared to PAC0 at 15.063 m2/g. The germination experiments were performed using mung beans. This study provides an opportunity for the application of pectin hydrogels in agriculture field specifically for home garden or rooftop cultivation.
摘要：
需要采取可持续农业举措来确保全世界人民的粮食安全。使用水凝胶的无土栽培方法可能会产生革命性的反应，并且是传统农业的生态和生产力更高的替代方法。本研究尝试从反照率黄色百香果（西番莲var。将果胶和活性炭的水凝胶与纯果胶水凝胶进行了比较；果胶-活性炭水凝胶（PAC）显示出具有优异亲水性的微孔结构，并显示出优异的持水性。然后用FTIR等各种仪器技术检查制备的水凝胶，SEM,XRD,拉曼,BET和流变性能。在BET分析中，当与15.063m2/g的PAC0相比时,PAC3显示出28.771m2/g的最高表面积。使用绿豆进行发芽实验。这项研究为果胶水凝胶在农业领域的应用提供了机会，特别是用于家庭花园或屋顶种植。
