- 了解纳米粒子对作物质量和产量的影响对于农业创新至关重要.
研究的目的:
- 研究铁素 (MnFe2O4) 纳米颗粒对小麦营养质量和产量的影响.
- 评估在小麦粒中MnFe2O4纳米颗粒的生物可用性和元素的积累.
主要方法:
- 实地实验涉及MnFe2O4纳米颗粒 (0-100 mg/L) 在小麦 (Triticum aestivum L.) 的叶子应用.
- 与离子对照 (MnSO4·H2O和FeSO4·7H2O) 在100mg/LNP度下进行比较.
- 分析谷物产量,收获指数,每的谷物数量,元素含量 (Fe,Mn,Ca),原蛋白和植物酸盐/铁 (PA/Fe) 含量.
主要成果:
- 在100 mg/L MnFe2O4 NP剂量下,观察到谷物产量 (5.0 t/ha) 和收获指数 (0.46) 的显著增加.
- 谷物中Fe (77 mg/kg),Mn (119 mg/kg) 和Ca (0.32 g/kg) 含量升高,每的谷物数量增加了14%.
- 与离子处理相比,提高了原蛋白含量 (15%) 和改善了铁的生物可用性 (将PA/Fe比率从11降至9.3). 在谷物中没有检测到NP积累.
结论:
- 叶子应用MnFe2O4纳米颗粒积极调节小麦谷物的营养质量和产量.
- MnFe2O4纳米颗粒适合作为富含Fe和Mn的肥料,因为它们的营养含量和生物可用性提高,而不会在可食用部分积累.

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.
