为了探索适合大批量样品快速、简便测定土壤有效硼的方法,对土壤有效硼测定方法进行研究。采用聚乙烯密封袋代替昂贵的石英三角瓶冷凝回流装置、以水浴法提取土壤中的有效硼、用H酸-甲亚胺比色法测定提取物中有效硼含量的改进方法,已成功地用于广西农垦桂柳片区农场3000多个土壤样品中有效硼的测定。该方法操作简单、快捷、无污染,而且具有很好的操作度和精确度。
In order to explore a rapid and simple method for determination of available boron in soil samples suitable for high-volume samples, the determination of available boron in soil was studied. Polyethylene sealed bags instead of expensive quartz flask condensate reflux device to extract the available soil water bath boron method, with H acid - methyl imine colorimetric determination of the effective boron content of the improved method has been successfully used Determination of available boron in more than 3000 soil samples from farmland in Gui Liu Area, Guangxi. The method is simple, fast and pollution-free, and has good operation and accuracy.
