摘要
中微量元素作为水稻生长发育所必需的营养元素,是多种酶系统的构成要素和激活剂,同时还参与光合作用、呼吸作用、激素合成及抗逆等一系列重要生理过程,对水稻生长及产量和品质的形成起着重要作用。因此,综述了对水稻具有显著作用的镁、锌、硒、铁元素的吸收、积累和代谢途径,以及它们对水稻产量和品质的影响,并深入分析了中微量元素在水稻生产中所面临的挑战,探讨了中微量元素在未来可持续发展农业中的必要性以及研究方向,旨在为通过合理施用中微量元素实现水稻高产和优质提供理论依据。
As essential nutrients for rice growth and development,medium and trace elements are the components and activators of enzyme systems,and also participate in a series of important physiological processes,such as photosynthesis,respiration,hormone synthesis and disease defense,which play vital roles in the formation of yield and quality for rice.Therefore,the effects of the absorption,accumulation and metabolic pathways of medium and trace elements,such as magnesium,zinc,seleniumon and iron,on rice yield and quality were reviewed,the challenges faced by the medium and trace elements in rice cultivation were analyzed,and the importance of medium and trace elements and the research direction in sustainable agriculture in the future were discussed,which provided theoretical basis for achieving high yield and high quality of rice.
