稀土应用于水稻的研究,起始于七十年初。十多年的试验研究,肯定了稀土对水稻增产效果,并对其增效机理作了相应的探。1980年以后逐步应用于大面积生产,取得好效果。增值与成本比为7～10:1,是一成本低,效益显著、简便易行的新技术措
Rare earths used in rice research, beginning in the early seventy years. More than ten years of experimental research have affirmed the effect of rare earth on rice yield, and made a corresponding exploration of its synergistic mechanism. After 1980 gradually applied to large-scale production, achieved good results. Value-added and cost ratio of 7 ~ 10: 1, is a low cost, significant benefits, easy to implement new technology measures
