Abstract:As the development of the utilization of rare-earth elements (REEs) in agriculture, REEs are used more and more as beneficial elements for the increase of crops yield and promotion of crops quality. Recently, great achievements were obtained in the utilization of REEs on production of crops such as food, vegetable, fruits etc. Through analyzing the accumulation of REEs in the different organs of plant bodies, the correlation of REEs content in plant bodies and in growing soils, and the selection and absorption of REEs in plants, this paper focuses on the distribution and transfer of REEs in the bodies of crops. Based on this, the paper summarizes the advance of domestic and overseas research, for the past few years, on the physiological effect of REEs on crop protective enzyme activities, absorption of nutrients and photosynthetic efficiency; effect of REEs on crop development and effect of REEs on crop yield increasing, quality promotion, economic returns enhancement. At the end of the paper, the call for strengthened effort on research has been made, which includes the effect of REEs on absorption of compound heavy metal, the molecular effect mechanism of crops quality, and the development and utilization of REEs nanoparticles.
