锌是人体必需的微量元素之一,在多种人体生理过程中发挥着重要作用。以含锌量低且锌生物利用效率低的谷类为主要膳食结构的人群锌摄入量往往不足,造成人体缺锌,影响人体健康。生物强化工程是基于现代生物育种技术和肥料应用为主的农艺措施,以提升谷类作物籽粒中锌的含量,提高膳食营养水平。综述了锌肥施用、作物籽粒锌吸收积累以及与人体锌素摄入、人体健康等方面的研究,探讨了锌肥合理施用对改善人体锌素营养的意义。
Zinc is one of the essential trace elements for human body and it plays an important role in a variety of human physiological processes. People who take cereals with low zinc content and low zinc bioavailability as the main dietary structure often have insufficient zinc intake, which causes zinc deficiency in human body and affects human health. Biofortification engineering is an agronomic measure based on modern biological breeding technology and fertilizer application to increase the zinc content in grains of cereal crops and increase the level of dietary nutrition. The researches on zinc fertilizer application, zinc absorption and accumulation in crop grains, and human zinc intake and human health are reviewed. The significance of reasonable application of zinc fertilizer to improve human zinc nutrition is discussed.
