Abstract

Metal-based nanoparticles (NPs) have garnered attention as a potential micronutrient nano-fertilizer. Most studies have focused on the effects of individual NP size on environmental risks and the uptake, translocation, and biological progress of NPs in plants. However, there is a lack of research on the effects of NPs of different sizes and their interactions with the nanoscale layers of plant leaves (hereafter, nanosheets), which may affect adhesion ability, anti-leaching properties, release rate, and fertilizer efficiency. In this study, various sizes (10, 20, 50, 100 nm, and 10 μm) of Fe3O4-NPs (Fe3O4-NPs) were applied to peanut (Fe strategy I, dicotyledon) and maize (Fe strategy II, monocotyledon) leaves to quantitatively compare their fertilization efficiency and anti-leaching effects. The optimal size for different crop leaves differed due to the distinct microstructures of the nanosheets on the leaf surface. In peanut, the optimal size was 50 nm, resulting in superior dry weight (1.32 g per plant), leaf iron concentration (483 μg g−1 DW), and adhesion amount (0.039 mg per plant). For maize, the optimal size was found to be 100 nm, leading to increased dry weight (1.98 g per plant), leaf iron concentration (258 μg g−1 DW), and adhesion amount (0.061 mg per plant). A model was developed to simulate the force and work exerted by Fe3O4-NPs of different sizes on leaf nanosheets, resulting in the optimal size consistent with the experimental findings. These findings will guide the selection of the optimized NP size for different leaves, thereby enhancing the efficiency of nano-fertilizer utilization and facilitating the development of new types of nano-fertilizers.

用于不同作物的 Fe3O4 纳米粒子的最佳尺寸取决于雨水条件下植物叶片独特的纳米级微观结构
作为一种潜在的微量营养元素纳米肥料,金属基纳米粒子(NPs)备受关注。大多数研究都集中在单个 NP 大小对环境风险的影响,以及 NP 在植物中的吸收、转运和生物进展。然而,对于不同尺寸的 NPs 及其与植物叶片纳米层(以下简称纳米层)之间的相互作用,可能会影响附着能力、抗浸出性能、释放率和肥效等方面的影响,目前还缺乏研究。本研究将不同尺寸(10、20、50、100 nm 和 10 μm)的 Fe3O4-NPs (Fe3O4-NPs)应用于花生(Fe 策略 I,双子叶植物)和玉米(Fe 策略 II,单子叶植物)叶片,以定量比较其肥效和抗淋溶效果。由于纳米片在叶片表面的微观结构不同,不同作物叶片的最佳尺寸也不同。花生的最佳尺寸为 50 nm,因此干重(每株 1.32 g)、叶片铁浓度(483 μg g-1 DW)和附着量(每株 0.039 mg)都很高。对于玉米,最佳尺寸为 100 纳米,可增加干重(每株 1.98 克)、叶片铁浓度(258 微克克-1 DW)和附着量(每株 0.061 毫克)。建立了一个模型来模拟不同大小的 Fe3O4-NPs 在叶片纳米片上施加的力和功,从而得出了与实验结果一致的最佳大小。这些发现将指导人们针对不同叶片选择最佳的 NP 大小,从而提高纳米肥料的利用效率,促进新型纳米肥料的开发。
