近年来我国不少农业科研单位将微量稀土用于农作物栽培试验,取得了一定的增产效果;许多地区已施用硝酸稀土或氯化稀土作为“微肥”以提高粮食、蔬菜和经济作物的产量。中国科学院植物研究所和我们合作,认为对微量稀土元素在植物中的生理功能有必要进行深入的研究。因此我们首先建立可靠而简便的分析方法。在最近几年中我们 In recent years, many agricultural research institutes in our country have used trace amounts of rare earths for crop cultivation experiments and achieved some stimulation effects. In many areas, rare earth nitrate or rare earth chloride has been used as a “micronutrient fertilizer” to increase the output of grain, vegetables and cash crops. Institute of Botany, Chinese Academy of Sciences and we work together, that the trace rare earth elements in the physiological functions of plants in-depth study. Therefore, we first establish a reliable and easy analytical method. In recent years we
