Innovative nano fertilizers based on nanoparticles present great potential for agriculture since they can stimulate growth and development in different crops. However, the efficiency of nanoparticles directly depends on their physicochemical characteristics, such as composition, shape, size, and the type of plant species. In this work, a material formed by mesoporous silica and iron oxide (FeO@MCM-48) was synthesized and used as a nano fertilizer for tomato crop. Materials with different percentages of iron (10, 20, 30, 40, and 50% by weight) were applied to study the effect of the amount of iron in the plants and compared with MCM-48 without iron and ferric chloride hexahydrate. Using X-ray diffraction (XRD), it was possible to identify the phases present in the system, and with Transmission Electron Microscopy (TEM), it was observed that the material is made up of a matrix of MCM-48 with embedded FeO nanoparticles with a size of 5 nm. Also, the results show that all treatments with nano fertilizers increased the content of photosynthetic pigments and carotenoids in leaves. The use of nano fertilizers can be a viable option to improve the crop growth and efficiency of nutrient use in plants.
基于纳米颗粒的创新型纳米肥料在农业领域具有巨大潜力,因为它们能够刺激不同作物的生长和发育。然而,纳米颗粒的效率直接取决于其物理化学特性,如组成、形状、大小以及植物种类。在这项工作中,合成了一种由介孔二氧化硅和氧化铁组成的材料(FeO@MCM-48),并将其用作番茄作物的纳米肥料。应用不同铁含量百分比(重量百分比分别为10%、20%、30%、40%和50%)的材料来研究铁含量对植物的影响,并与不含铁的MCM-48和六水合氯化铁进行比较。通过X射线衍射(XRD)能够识别系统中存在的物相,利用透射电子显微镜(TEM)观察到该材料由MCM-48基质和嵌入的尺寸为5纳米的FeO纳米颗粒组成。此外,结果表明,所有使用纳米肥料的处理均增加了叶片中光合色素和类胡萝卜素的含量。使用纳米肥料可能是提高作物生长和植物养分利用效率的可行选择。
