Global food demand has increased in tandem with the world’s growing population, prompting calls for a new sustainable agricultural method. The scarcity of fertile soil and the world’s agricultural land have also become major concerns. Soilless and microgreen farming combined with nanotechnology may provide a revolutionary solution as well as a more sustainable and productive alternative to conventional farming. In this review, we look at the potential of nanotechnology in soilless and microgreen farming. The available but limited nanotechnology approaches in soilless farming include: (1) Nutrients nanoparticles to minimize nutrient losses and improve nutrient uptake and bioavailability in crops; (2) nano-sensing to provide real-time detection of p H, temperature, as well as quantifying the amount of the nutrient, allowing desired conditions control; and (3) incorporation of nanoparticles to improve the quality of substrate culture as crop cultivation growing medium. Meanwhile, potential nanotechnology applications in soilless and microgreen farming include: (1) Plant trait improvement against environmental disease and stress through nanomaterial application; (2) plant nanobionics to alter or improve the function of the plant tissue or organelle; and (3) extending the shelf life of microgreens by impregnating nanoparticles on the packaging or other preservation method.

无土微绿农业纳米技术发展的一些新机遇

全球粮食需求随着世界人口的增长而增加，促使人们呼吁采用新的可持续农业方法。肥沃的土壤和世界农业用地的稀缺也成为主要问题。无土和微绿农业与纳米技术相结合，可能会提供一种革命性的解决方案，以及一种比传统农业更具可持续性和生产力的替代方案。在这篇评论中，我们着眼于纳米技术在无土和微绿农业中的潜力。无土农业中可用但有限的纳米技术方法包括： (1) 营养纳米粒子，以最大程度地减少营养损失并提高作物对营养的吸收和生物利用度；(2) 纳米传感提供实时检测 p H、温度，以及量化养分量，允许所需的条件控制；(3) 掺入纳米颗粒以提高作为作物栽培生长介质的基质培养物的质量。同时，纳米技术在无土和微绿农业中的潜在应用包括：（1）通过纳米材料应用改善植物性状对抗环境疾病和胁迫；(2) 植物纳米仿生学改变或改善植物组织或细胞器的功能；(3) 通过在包装上浸渍纳米颗粒或其他保存方法来延长微型蔬菜的保质期。(1) 通过纳米材料应用改善植物抗环境病害和胁迫的性状；(2) 植物纳米仿生学改变或改善植物组织或细胞器的功能；(3) 通过在包装上浸渍纳米颗粒或其他保存方法来延长微型蔬菜的保质期。(1) 通过纳米材料应用改善植物抗环境病害和胁迫的性状；(2) 植物纳米仿生学改变或改善植物组织或细胞器的功能；(3) 通过在包装上浸渍纳米颗粒或其他保存方法来延长微型蔬菜的保质期。
