摘要
目的 本研究探讨了农业土壤中的镉污染这一严重问题，它对作物产量和食品安全构成了巨大风险。本研究的目的是在大规模田间试验中评估所选最佳土壤改良剂的功效。方法按泥浆和腐植酸的施用量为 0.5%，石膏和 Fe2O3 的单独施用量为 5 mg/kg，同时叶面施用纳米铁颗粒 5 mg/L：PM、HA、GYP、Fe、PM + Fe Nps、HA + Fe Nps、GYP + Fe Nps 和 Fe + Fe Nps 的固定效率分别为 100%、102%、104%、104%、105%、102%、105% 和 105%。此外，对照植物的生长、光合作用活性降低，丙二醛和过氧化氢水平升高，表明存在氧化损伤。研究结果应用这些添加剂并叶面喷洒 Fe Nps 可有效减轻玉米作物的镉毒性，从而改善生长、生物量、光合色素和抗氧化酶活性。新颖性/改进之处这些发现突出了探索创新方法的重要性，即结合不同的添加剂和叶面喷施纳米颗粒来减轻镉污染和提高土壤健康，从而为全球确保食品安全和保障做出贡献。
Exploring the impact of organic and inorganic amendments, with foliar application of iron nanoparticles, on cadmium stabilization and growth of maize in wastewater irrigated-soil
Objectives
This study addresses the critical issue of Cd contamination in agricultural soils, posing substantial risks to crop productivity and food safety. While prior pot experiment has undertook this issue on a small scale, this study aims to evaluate the efficacy of selected best soil amendments, at a large-scale field experiment.
Methodology
Press mud and humic acid were applied at 0.5%, while gypsum and Fe2O3 were applied at 5 mg/kg alone and with foliar application of Fe nanoparticles at 5 mg/L.
Analysis
Comparative analysis with control revealed the immobilization efficiency of all amendments in descending order of effectiveness as follows: 100, 102, 104, 104, 105, 102, 105, and 105% for PM, HA, GYP, Fe, PM + Fe Nps, HA + Fe Nps, GYP + Fe Nps, and Fe + Fe Nps. Additionally, reduced growth, photosynthetic activities, and elevated levels of malondialdehyde and hydrogen peroxide, indicative of oxidative damage in control plant.
Findings
Application of these amendments with foliar spraying of Fe Nps effectively mitigates Cd toxicity in maize crops, leading to improved growth, biomass, photosynthetic pigments, and antioxidant enzyme activities.
Novelty/Improvement
These findings highlight the significance of exploring innovative approach of combining different amendments with foliar application of nanoparticles to mitigate Cd contamination and enhance soil health, thereby contributing to global efforts in ensuring food safety and security.
