Straw return and plastic film mulching are two critical management measures that not only maintain high stable crop yields, but also have a significant impact on the ecological environment. However, there is still lack of research comprehensive effects straw different treatments Thus, 2-year field experiment was conducted six treatments, which included main namely (SR) non-straw (NR), three sub-treatments, no (CK), (PM) fully biodegradable (BM), were applied in garlic cropping system. Based life cycle assessment method, endpoint damage categories, resource consumption, global warming potential, environmental acidification, eutrophication, human health, ecotoxicity, assessed. Furthermore, we evaluated costs economic benefits optimized treatment used mulch off-farm. The results indicated impacts damages system ranked as consumption. SR-BM had lowest composite index at 27.68 per unit area, followed by SR-PM 27.75. All categories for PM BM lower than CK t yield, with being most economically efficient, yielding 3691.03 CNY·t−1 exceeding SR-CK 7.26%. Fertilizer inputs primary contributor to accounting about 72.80% these five impacts. Crop protection significantly affected helped minimize pesticide use, thereby reducing potential health Compared incineration waste power generation, generation recycling granulation offered positive more effective offset strategies. In conclusion, synergistic cultivation measure offers both benefits. For mulch, can be reduced granulation.

Introduction Polyethylene mulch film (PE) is a key agricultural practice for enhancing crop production and income in water-scarce regions. However, the complete recycling of PE remains challenging, resulting persistence residual fragments soil, which compromises soil structure negatively impacts growth yield potential. Although biodegradable (BEMF) considered promising alternative, underlying mechanisms governing its regulation water thermal dynamics, as well subsequent on productivity, are yet to be fully elucidated. Methods Therefore, comprehensive understanding how BEMF influences regimes, development crucial assessing ecological adaptability. In this study field plot experiments were carried out over three consecutive growing seasons (2021 - 2023) under irrigation quotas: W1 (63.6% evapotranspiration [ETc], 315 mm), W2 (81.8% ETc, 405 W3 (100% 495 mm). Results This systematically evaluated films (BEMF: B1 B2) hydrothermal cotton photosynthetic use efficiency varying quotas. Furthermore, economic benefits fields these treatments analyzed. The findings revealed that left 12.95 kg·ha -1 after mechanical recovery, while exhibited no such residue accumulation. reduced effective temperature by 100 111°C content (SWC) 2.82 9.42% compared PE. These adverse effects significantly impaired net rate (Pn) product Specifically, decreased Pn 8.42 18.09%, accumulation 10.74 26.41%, 651 1079 relative PE, particularly level. Increasing quota mitigated heat deficits, enhanced boosted 1.76 31.72%, increased 552 12,423 CNY·ha . Discussion summary, provides new regional adaptation scheme BEFM, highlighting conventional conditions, BEFM cannot substitute advantages PEFM. Nevertheless, application an additional 90 mm effectively mitigates losses associated with eliminating risk fragment soil. offer valuable insights advancing green sustainable management ecosystems.

This study applied a life cycle assessment (LCA) and SimaPro software to calculate the carbon footprint of ecological plastic film in Qingcheng Town. The results indicate that reduction efficiency compared 0.01 mm PE ranged from 30.8% 40.0%, without accounting for substitution humus chemical fertilizers. When was considered, range increased 70.2% 74.2%. Ecological achieved greatest emission final treatment stage, 54.1% total CO2 reduction, followed by production stage at 44.8%, while transportation phase contributed only 1.1%. Projecting 2030, if half cultivated land Shanxi Province uses instead film, 19.7% emissions is expected. Full coverage with could raise this 39.4%. To encourage its adoption, suggests government offers financial subsidies enterprises or farmers, promotes agricultural taxes, supports trading. With price tax exceeding 67.1 CNY/t, achieves cost parity film.
