In order to reduce the negative ecological effects and environmental pollution caused by large-scale herbicide application in rice cultivation, a straw fiber mulch film (FMF) was developed. This study applied high-temperature enzymatic solution technology as a pretreatment process for rice straw (RS) fibers, causing beneficial physicochemical structural changes. Chemical composition, crystallinity index (CrI), degree of polymerization (DP), thermal stability, and other parameters of deconstructed RS fibers were analyzed. The change in CrI showed that appropriate pretreatment times can improve crystallinity, while excessively long pretreatment times caused crystallinity to sharply decrease from 44.65 wt.% to 41.34 wt.%. The C=O bonds between lignin and hemicellulose were almost completely destroyed, confirming the deconstruction of linkages within RS fibers, making the material significantly softer and looser. Compared with untreated straw fibers, the mechanical pulping beating time decreased significantly, reducing energy consumption by 43.75%. The FMFs prepared with appropriate fermenting times exhibited improved mechanical properties. The tensile strength of FMF prepared using biological pretreatment fermentation (BPF) as a raw material increased from 11.26 N m g^-1 to 15.68 N m g^-1, exhibiting an increase of 39.25% compared to traditional fermentation (TF). This work provides a novel method, which has the potential to effectively control herbicides and support the development of sustainable agricultural systems.

为了减少大规模除草剂在水稻种植中造成的负面生态影响和环境污染，开发了秸秆纤维覆盖膜（FMF）。这项研究应用高温酶解技术作为稻草（RS）纤维的预处理工艺，从而引起有益的理化结构变化。分析了解构的RS纤维的化学组成，结晶度指数（CrI），聚合度（DP），热稳定性和其他参数。CrI的变化表明适当的预处理时间可以改善结晶度，而过长的预处理时间导致结晶度从44.65重量％急剧降低至41.34重量％。木质素和半纤维素之间的C = O键几乎被完全破坏，证实了RS纤维内部键的解构作用，使该材料明显更柔软和更松散。与未处理的稻草纤维相比，机械制浆的打浆时间显着减少，减少了43.75％的能耗。以适当的发酵时间制备的FMF显示出改善的机械性能。以生物预处理发酵（BPF）为原料制备的FMF的拉伸强度从11.26 N mg增加^-1至15.68 N mg ^-1，与传统发酵（TF）相比增加了39.25％。这项工作提供了一种新颖的方法，具有有效控制除草剂和支持可持续农业系统发展的潜力。
