摘　　要：建立了一种应用沸水浸提-ICP-AES快速测定土壤中有效硼的方法。采用聚乙烯瓶代替昂贵的石英三角瓶和石英回流器,在沸水中提取土壤中的有效硼,用ICP-AES代替姜黄素分光光度法测定提取物中的有效硼含量。该法操作简单、快捷、无污染,而且具有很好的准确度和精密度。该法可成功地用于赣南脐橙园1500个土壤样品中有效硼的测定。A new method for the determination of available boron in soil by inductively coupled plasma-atomic emission spectroscopy（ICP-AES）with boiling water extraction was developed.The soil samples were put into boiling water in a polyethylene bottle,instead of quartz flask and reflux condenser,and available boron in soil was extracted in boiling water bath,and determined by ICP-AES,instead of curcumine colorimetry.The method is not only simple and rapid but also shows satisfying precision and accuracy,and is successfully applied to the determination of soil available boron in Gannan navel orange orchards.
