自从1955年澳大利亚物理学家A·Walsh博士创立原子吸收光谱分析法以来.由于该法具有测定快速、精确、干扰少、手续简便等优点,目前已在工业、医学、农业等各方面广泛应用.近年来,北京光学仪器厂、上海分析仪器厂等先后试制成功国产的原子吸收分光光度计,为广泛地应用这一新技术创造了条件.在农业方面,对作物和土壤中某些常量及微量金属元素含量状况的研究,已日益成为迫切需要解决的问题.如有些水稻土缺锌经施用锌肥,取得了良好的增产效应;柑桔园缺铁,影响产量;桑园缺铜,引起桑

Since the creation of atomic absorption spectrometry by Australian physicist Dr. A. Walsh in 1955, this method has been widely used in industry, medicine, agriculture and other fields due to its advantages of fastness, precision, less interference and simple procedures. In recent years, Beijing Optical Instrument Factory, Shanghai Analytical Instrument Factory has trial-produced domestically produced atomic absorption spectrophotometer, to create a wide range of applications of this new technology in agriculture, the crops and soil some of the constant and trace The research on the status of metal elements has increasingly become an urgent problem to be solved.If some of the paddy soil is deficient in zinc and zinc fertilizer is applied, good yield-increasing effect has been achieved; citrus orchards lack iron and affect the yield;
