Research Progress on Effects of Medium and Trace Elements on Yield and Quality of Rice
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.
