稀土是一些化学性质相似的金属元素的总称,它包括元素周期表中镧系15种元素及与它们性质相近的钇、钪元素。稀土微肥是混有稀土的水溶性盐类(如硝酸稀土等),是一种新兴的微量元素肥料。近年来我国对稀土微肥的增产原理及使用方法进行了广泛的研究,初步肯定了稀土微肥对多种作物有改良品质和提高产量的作用。而在各种作物中,甜菜对稀土最为敏感。为此,我们于1985—1987年研究了稀土微肥对新疆甜菜生长及产量的影响。 Rare earth is a general term for some chemically similar metal elements. It includes 15 elements of the lanthanide series and yttrium and scandium elements similar in their properties to the periodic table. Rare earth fertilizer is mixed with rare earth soluble salts (such as rare earth nitrate, etc.), is an emerging trace element fertilizer. In recent years, China’s R & D production of rare earth fertilizer principles and methods of using a wide range of research, initially affirmed the role of rare earth fertilizer on a variety of crops to improve quality and increase production. In a variety of crops, beets are the most sensitive to rare earths. To this end, we studied in 1985-1987 rare earth fertilizer on the growth and yield of sugar beet in Xinjiang.
