摘要
采用大田试验,研究了锌、铁、钼等配合施用对紫花苜蓿微量元素含量及年积累量的影响。结果表明,微量元素肥料通过适当配合施用能提高苜蓿中锌、钼、锰、硼的含量,降低钴含量,而抑制苜蓿对土壤中铁的吸收,但对苜蓿铜含量没有显著影响。同时,显著降低了苜蓿钴年积累量,而对苜蓿锌、铁、锰的年积累量没有显著的影响,但显著提高苜蓿钼、硼、铜的年积累量。
Effects of combined application of Zinc （Zn）, Iron （Fe）, and Molybdenum （Mo） on the content of trace elements of alfalfa were studied by field experiment. The result indicated that the appropriate application of trace element fertilizer could increase the content of Zn, Mo, Mn and B in alfalfa , while reduce the content of Co ; and also restrain the alfalfa absorbing Fe from the soil, but there was not remarkable influence on copper（Cu） content in the alfalfa. The appropriate application of trace element fertilizer can significantly reduce the annual accumulation of Co, and there was not remarkable influence on the annual accumulation of Mn, Fe and Zn in alfalfa, and increase the annual accumulation of B, Cu and Mo significantly.
