英文摘要	To combat severe soil desertification and sandstorms, the application of appropriate hydrogels to dry land/desert is a promising solution to advance sustainable water irrigation and retention, and even realize intelligent agriculture. To this end, the development of a hydrogel with stable monitoring functions and good mechanical properties to maintain the swelling capability under soil would be significant for intelligent agriculture applications. Herein, we report a robust bio-based hydrogel with excellent mechanical properties and unique fluorescence performance for monitoring irrigation applications. This bio-hydrogel possesses a double cross-linked interpenetrating supramolecular network in a bacterial cellulose (BC) porous matrix, which provides its high tensile/compressive strength (similar to 0.96/1.3 MPa) and excellent Young's modulus (similar to 6.67 MPa, vs. 0.01-1.0 MPa for reported agricultural hydrogels), as well as high strength retention after experiencing repeated swelling/drying and long-term compressive processes. Furthermore, the hydrogel displays unique non-traditional fluorescence with excellent stability even under extreme environmental conditions, such as high/low temperature and various organic solvents. The excellent fluorescence characteristics offer the potential to realize visualized agricultural irrigation. This study not only provides a distinctive bio-based hydrogel with broadened applications, but also presents new insight to promote the development of sustainable agriculture.
