摘要

锌(Zn)对人类、动物和植物都有重要的营养价值,是它们饮食需求中的重要元素。本研究评估了四种不同浓度(0、0.5、1.0 和 5.0 g/L)的氧化锌纳米颗粒(ZnONPs)溶液对生长在缺锌土壤中的豌豆植物的影响,间隔时间为 20 天,目的是修复缺锌问题并提高锌强化效果。采用溶胶-凝胶法合成了纳米氧化锌颗粒,并通过紫外-可见光谱、傅立叶变换红外光谱、扫描电子显微镜、X 射线衍射和 EDX 图谱对其进行了表征。土壤样本的微生物数量、化学性质、脱氢酶活性、植被特征、养分状况和产量参数都按照各自的方法进行了分析。溶液颜色变为灰白色证实了 ZnONPs 的合成。ZnONPs 通过紫外可见光谱进行表征,在 380 纳米处有一个宽峰。傅立叶变换红外光谱证实了 NH/OH、C-H、C-C、C-O、C-N、Cl-C-O 等官能团的存在。XRD 图谱描述了六方排列的晶体结构。ZnONPs 的 EDX 图谱显示锌的成分占 45.9%,氧的成分占 54.05%。扫描电镜图像显示,ZnONPs 的尺寸为 37 纳米。浓度为 5.0 g/L 的 ZnONPs 能明显改善水稻的生长和产量参数。然而,施用浓度为 1.0 g/L 的 ZnONPs 时,根系特征值最高。5.0 g/L ZnONPs 处理时,土壤中的微生物数量和酶活性(如存活细胞数和脱氢酶活性)最高。ZnONPs 的处理除了改善植物的锌含量外,还成功地恢复了缺锌症状,尽管这种反应与浓度有关。这些研究结果表明,ZnONPs 可有效用于低土壤锌浓度下栽培的豌豆植物的锌修复和锌强化。本研究强调了 ZnONPs 在解决微量营养元素缺乏、促进作物生长和增强土壤健康方面的潜力,为锌在农业中的应用提供了一种可持续和可控的方法。

Innovative Approaches for Sustainable Zinc Nutrition and Crop Yield Enhancement in Pea Plants Using Zinc Oxide Nanoparticles

Zinc (Zn) possesses nutritional importance for humans, animals, and plants, making it a crucial element in their dietary requirements. In the current study, the effect of zinc oxide nanoparticles (ZnONPs) solution at four different concentrations (0, 0.5, 1.0 and 5.0 g/L) at 20-day interval on pea plants grown in Zn-deficient soil was assessed for remediation of Zn deficiency and enhanced Zn fortification. Zinc oxide nanoparticles were synthesized by using sol-gel method and characterized by UV-Vis spectroscopy, Fourier transform infrared (FTIR), Scanning Electron Microscopy (SEM), and X-Ray diffraction (XRD) and EDX pattern. The soil samples were analysed for microbial counts, chemical properties, dehydrogenase activity and vegetative characteristics, nutrient profile, and yield parameters according to their respective methods. The change of solution colour to off-white confirmed the synthesis of ZnONPs. ZnONPs were characterized by UV-Vis spectroscopy with a broad peak at 380 nm. The presence of NH/OH, C-H, C-C, C-O, C-N, Cl-C-O functional groups were confirmed by FTIR spectrum. The crystalline structure with hexagonal arrangements was described by the XRD pattern. The EDX pattern of ZnONPs showed the zinc composition as 45.9% and oxygen was 54.05%. The SEM images showed that the size of ZnONPs was of 37 nm. The application of ZnONPs at a concentration of 5.0 g/L significantly improved the growth and yield parameters. However, the highest value for root characteristics was attained with the application of ZnONPs at a concentration of 1.0 g/L. The microbial soil counts and enzyme activities such as viable cell counts, and dehydrogenase activity was highest at 5.0 g/L ZnONPs treatment. The treatment of ZnONPs successfully reverted the symptoms of Zn-deficiency besides the improvement of the Zn content of plant, although the response was concentration dependent. These findings indicate that ZnONPs can be effectively used for remediation and Zn fortification in pea plants cultivated under low soil Zn concentrations. The present study emphasizes the potential of ZnONPs to address micronutrient deficiencies, promote crop growth, and enhance soil health, offering a sustainable and controlled approach to zinc applications in agriculture.
