Research progress on the impact of microplastics on crops LI Wang-wang, ZHANG Le, CAI Hui, TIAN Zhi-quan, ZHANG Zhao-wei HUBEI AGRICULTURAL SCIENCES    2024, 63 (6): 53-59.   DOI: 10.14088/j.cnki.issn0439-8114.2024.06.008 Abstract （807）      PDF （1659KB）（3447）       Knowledge map    Save Microplastics were plastic particles with a size of smaller than 5 millimetres, which were abundant and persistent in soil, posing a serious global environmental problem. Microplastics entered the crop body through the roots or leaves and affected different stages of crop growth. The pathways of microplastics entering the crop body and the detection methods of microplastics in crops of existing research were summarized, and the effects of different microplastics on crop germination rate, biomass, photosynthesis, oxidative stress system, nutrients, gene expression, etc. were explored. It was found that the influence of microplastics on crops varied with the characteristics of microplastics, crop species and environmental factors. Under certain experimental conditions, microplastics had no effect or a positive effect on crops. However, more studies had shown that microplastics could inhibit crop growth and ultimately affect crop yield. Moreover, microplastics could be enriched upward through food chains and affect human health. Reference | Related Articles | Metrics

The intrinsic mechanism and empirical test of the digital economy empowering urban-rural integration development LIU Li, YANG Guang-xi HUBEI AGRICULTURAL SCIENCES    2025, 64 (6): 232-239.   DOI: 10.14088/j.cnki.issn0439-8114.2025.06.037 Abstract （355）      PDF （1635KB）（892）       Knowledge map    Save Based on the provincial panel data of China from 2012 to 2021, the impact of the development of the digital economy on urban-rural integration and its mechanisms were examined by using fixed-effect models, mediating-effect models and threshold-effect models. The results showed that the development of the digital economy could significantly promote the process of urban - rural integration in China. Compared with regions with a high level of urban-rural integration, the development of the digital economy had a greater promoting effect in regions with a low level of urban-rural integration. This mechanism was realized through two channels: Labor transfer and enhancing regional development capabilities. Further exploration was conducted and it was revealed that the development of the digital economy presented non-linear characteristics in urban-rural integration. When the regional economic development level crossed two thresholds, the enabling effect of the digital economy on the development of urban-rural integration gradually slowed down. Therefore, local digital economy construction should be continuously improved, labor transfer should be rationally guided, the endogenous driving force of regional development should be strengthened, and differential policies should be implemented according to local conditions, so as to share the dividends of the digital economy and comprehensively promote the in-depth integration of urban and rural areas.

Inversion of soil hydrodynamic parameters based on improved butterfly optimization algorithm LIU Xue, LIANG Su-yu, ZHU Yan-jie, WANG Huai-yu HUBEI AGRICULTURAL SCIENCES    2025, 64 (5): 63-69.   DOI: 10.14088/j.cnki.issn0439-8114.2025.05.010 Abstract （444）      PDF （2889KB）（744）       Knowledge map    Save To effectively obtain the parameters to reflect the process of water movement in soil, a hydrodynamic parameter inversion model was proposed based on an improvd butterfly optimization algorithm (IBOA). Building upon the theoretical framework of soil water movement equations, firstly, the butterfly optimization algorithm (BOA) was used to find the optimal solution through the combination of global search and local search, and the switching probability in the BOA was obtained through the random walk algorithm, so as to improve the situation that the algorithm was easy to fall into the local optimum. Secondly, the improved algorithm was applied to the data under the conditions of using HYDRUS-1D to simulate the uniform distribution of unsaturated soil moisture in the initial water content. At last, the appropriate objective function was selected and the improved butterfly optimization algorithm was used for inversion. The results showed that the average relative error of the parameter inversion value of the improve butterfly optimization algorithm was 0.22%~3.60%, which could better invert soil hydrodynamic parameters. The improved butterfly optimization algorithm could effectively improve the accuracy of the estimated parameters and obtain high-quality global optimal solutions.

Biochar with different particle sizes （>1.0 mm, 0.5~1.0 mm, 0.001~0.5 mm） was prepared, and TiO2-photocatalytic degradation experiments were conducted to systematically analyze the characteristics of the biochar and the efficacy of degrading and removing endogenous PAHs with different particle sizes. The results showed that the endogenous PAHs content in corn stover biochar was 76.1 mg/kg, predominantly comprising 4-ring and 5-ring PAHs, significantly exceeding the limit value for basic biochar PAHs （20 mg/kg） set by the International Biochar Initiative （IBI）. TiO2-photocatalysis could significantly reduce the content of endogenous PAHs in biochar. After photocatalytic degradation, the endogenous PAHs content in the three particle sizes of biochar ranged from 3.3 to 14.9 mg/kg, with degradation rates for total PAHs ranging from 55.2% to 95.6%. The maximum degradation rate for high-ring PAHs reached 97.1%, while low-ring PAHs reached 62.0%. The 0.001~0.5 mm particle size biochar exhibited the highest degradation rate of 95.6% after 40 minutes of light exposure, and the toxicity equivalent value decreased from 9.096 mg/kg to 0.088 mg/kg, significantly below the thresholds set by the European Biochar Certification（4 mg/kg） and the International Biochar Initiative（6 mg/kg）. The study demonstrated that TiO2-photocatalysis effectively degraded endogenous PAHs in biochar of different particle sizes, ensuring the safety of biochar and its products for application in agricultural fields.
