摘要:本文综述了纳米纤维素基水凝胶的制备策略及其在农业领域的应用研究。首先，介绍了机械法结合纤维素酶解、TEMPO氧化等纤维素纳米纤维（CNF）原料的预处理方法，探讨了保留适量木质素对CNF制备及性能的提升作用。然后，总结了基于物理交联（如冻融、离子配位）和化学交联（如醚化、酯化）构筑水凝胶网络的方法策略和优化途径，重点综述了纳米纤维素基水凝胶在肥料负载缓释、农药光稳定性保护及土壤微生态调节方面的应用现状。最后，分析了纳米纤维素基水凝胶现存的吸水倍率低、田间降解速率与作物生长周期错配及湿态机械强度不足等关键挑战，并对其未来优化方向进行了展望。
Abstract:This review summarized recent advances in the preparation strategies of nanocellulose-based hydrogels and their applications in agriculture. First, pretreatment methods for cellulose feedstocks used to produce cellulose nanofibers (CNF) were introduced, including mechanical treatment combined with enzymatic hydrolysis and TEMPO-mediated oxidation, with particular emphasis on the role of appropriate lignin retention in improving CNF production and properties. Subsequently, strategies for constructing and optimizing hydrogel networks through physical crosslinking (such as freeze-thaw treatment and ionic coordination) and chemical crosslinking (such as etherification and esterification) were summarized. Particular attention was given to the current applications of nanocellulose-based hydrogels in fertilizer loading and controlled release, protection of pesticides against photodegradation, and regulation of soil microbiota. Finally, key challenges facing nanocellulose-based hydrogels were discussed, including limited water absorption capacity, a mismatch between field degradation rates and crop growth cycles, and insufficient mechanical strength under wet conditions. Future directions for optimizing these materials were proposed.
