我国植物缺铁黄化病相当普遍,在北方石灰性土壤上表现更为严重,致使某些水果及作物产量大幅度下降。中国农科院原子能利用所、中科院山西煤化所和北京土肥站、山西农大土化系等单位的大量研究和试验示范表明,使用黄腐酸(FA)螯合铁是防治此病的经济有效办法,铁的吸收和移动效果都优于国外使用的EDTA铁,并且由于FA的生理效应,作物复绿快、增产多,因此引起人们的关注。 由于铁是此种肥料的主要成份,研究一种经济快速准确的分析Fe的方法就显得十分必要。同时还由于FA对铁的螯合能力和 Phytophthora infestans is quite common in our country. It is more serious in the calcareous soil in the north, resulting in a significant drop in the output of some fruits and crops. The Chinese Academy of Agricultural Sciences Institute of Atomic Energy, Chinese Academy of Sciences Shanxi Coalification Institute and Beijing Tu Fertilizer Station, Shanxi Agricultural University and other units of a large number of research and experimental demonstration shows that the use of fulvic acid (FA) chelated iron is a cost-effective way to control the disease , Iron absorption and mobility are superior to the EDTA iron used abroad, and because of the physiological effects of FA, the crop quickly green, yield more, so aroused people’s attention. Since iron is the main component of this fertilizer, it is necessary to study a method for the rapid and accurate analysis of Fe. At the same time due to FA chelation capacity and iron
