摘　　要：Agriculture is the foundation of social development.Under the pressure of population growth,natural disasters,environmental pollution,climate change,and food safety,the interdisciplinary"new agriculture"is becoming an important trend of modern agriculture.In fact,new agriculture is not only the foundation of great health and new energy sources,but is also the cornerstone of national food security,energy security,and biosafety.Hydrogen agronomy focuses mainly on the mechanism of hydrogen gas(H2)biology effects in agriculture,and provides a theoretical foundation for the practice of hydrogen agriculture,a component of the new agriculture.Previous research on the biological effects of H2 focused chiefly on medicine.The mechanism of selective antioxidant is the main theoretical basis of hydrogen medicine.Subsequent experiments have demonstrated that H2 can regulate the growth and development of plant crops,edible fungus,and livestock,and enhance the tolerance of these agriculturally important organisms against abiotic and biotic stresses.Even more importantly,H2 can regulate the growth and development of crops by changing the soil microbial community composition and structure.Use of H2 can also improve the nutritional value and postharvest quality of agricultural products.Researchers have also shown that the biological functions of molecular hydrogen are mediated by modulating reactive oxygen species(ROS),nitric oxide(NO),and carbon monoxide(CO)signaling cascades in plants and microbes.This review summarizes and clarifies the history of hydrogen agronomy and describes recent progress in the field.We also argue that emerging hydrogen agriculture will be an important direction in the new agriculture.Further,we discuss several scientific problems in hydrogen agronomy,and suggest that the future of hydrogen agronomy depends on contributions by multiple disciplines.Important future research directions of hydrogen agronomy include hydrogen agriculture in special environments,such as islands,reefs,aircraft,and outer space.农业是社会发展的基础。在人口增长、自然灾害、环境污染、气候变化和食品安全等诸多压力下,跨学科的新农业正在成为现代农业的发展方向之一。新农业不仅是大健康和新能源的基础,同时也是国家粮食安全、能源安全以及生物安全的基石。氢农学主要研究农业领域中氢气(H2)生物学效应的相关机理,为从属于新农业的氢农业实践提供相关理论基础。过去,H2生物学效应的研究主要集中在医学方面,选择性抗氧化是氢医学的主要理论依据。随后的实验表明,H2也可以调节农作物、食用微生物和家畜的生长发育,增强它们对各种胁迫的耐受性。更重要的是,H2还可以改变土壤中微生物的群落结构,进而调节农作物生长。使用H2还可以提高农产品的营养价值和采后品质。研究人员还表明,H2的生物学功能是通过调控植物与微生物等体内活性氧(ROS)、一氧化氮(NO)和一氧化碳(CO)信号级联来介导的。本文总结了氢农学的发展历程,综述了相关研究的新进展。我们认为崭露头角的氢农业将是新农业发展的方向之一。我们还讨论了目前氢农学存在的一些科学问题,指出氢农学的未来需要结合多学科的优势。此外,例如岛礁、飞行器和外太空等特殊环境下的氢农业也将成为氢农学的重要研究方向。
