“…The effect of MPs on photosynthesis is mainly related to environmental conditions such as MPs exposure concentration and size. 140 The size relationship between plant surface pores and the diameter of nanoplastics determines whether they are likely to be absorbed by plants, resulting in different plant toxicity effects. 134 When the concentration of microplastics was low (0−50 mg/kg), the improvement of photosynthetic pigments was significant.…”

Microplastics are emerging persistent pollutants which have attracted increasing attention worldwide. Although microplastics have been widely detected in aquatic environments, their presence in soil ecosystems remains largely unexplored. Plastic debris accumulates in farmland, causing serious environmental problems, which may directly affect food substances or indirectly affect the members in each trophic level of the food chain. This review summarizes the origins, migration, and fate of microplastics in agricultural soils and discusses the interaction between microplastics and the components in farmland from the perspectives of toxicology and accumulation and deduces impacts on ecosystems by linking the organismal response to an ecological role. The effects on farmland ecosystem function are also discussed, emphasizing the supply of agricultural products, food chain pathways, carbon deposition, and nitrogen cycling and soil and water conservation, as microplastic pollution will affect agricultural ecosystems for a long period, posing an ecological risk. Finally, several directions for future research are proposed, which is important for reducing the effect of microplastics in agricultural systems.

“…In addition, MPs are further aged in the soil and their additives are directly toxic to plants [46] . Numerous studies have demonstrated the adverse effects of exposure to soil MPs on plants, especially crops, including inhibition of seed germination and plant growth, reduction in biomass, interference with metabolism, and genotoxicity [76,[79][80][81] . However, in recent years, some MPs have also been found to promote plant growth.…”

“…However, much of the waste plastic film remains in the soil after harvesting. With polyethylene as raw material, plastic film is decomposed into residual film and microplastics over time under natural conditions (Qi et al, 2020;Zhang et al, 2022). However, complete decomposition of plastic film in the soil requires 200 to 400 years (He et al, 2009).…”

To accurately evaluate residual plastic film pollution in pre-sowing cotton fields, a method based on modified U-Net model was proposed in this research. Images of pre-sowing cotton fields were collected using UAV imaging from different heights under different weather conditions. Residual films were manually labelled, and the degree of residual film pollution was defined based on the residual film coverage rate. The modified U-Net model for evaluating residual film pollution was built by simplifying the U-Net model framework and introducing the inception module, and the evaluation results were compared to those of the U-Net, SegNet, and FCN models. The segmentation results showed that the modified U-Net model had the best performance, with a mean intersection over union (MIOU) of 87.53%. The segmentation results on images of cloudy days were better than those on images of sunny days, with accuracy gradually decreasing with increasing image-acquiring height. The evaluation results of residual film pollution showed that the modified U-Net model outperformed the other models. The coefficient of determination(R2), root mean square error (RMSE), mean relative error (MRE) and average evaluation time per image of the modified U-Net model on the CPU were 0.9849, 0.0563, 5.33% and 4.85 s, respectively. The results indicate that UAV imaging combined with the modified U-Net model can accurately evaluate residual film pollution. This study provides technical support for the rapid and accurate evaluation of residual plastic film pollution in pre-sowing cotton fields.
