| 摘 要： | 农业生产的发展和人们对环境质量的关注对土壤养分分析提出了更高的要求,土壤养分分析需要应对更大数量的样品和需要更快的分析速度,因此现代化成为土壤养分分析的必由之路。本文对近20年来联合提取剂(AB-DTPA、0.5 mol/L NaHCO3水溶液、0.01 mol/L CaCl2水溶液、Kelowna提取剂、锶-柠檬酸提取液、水)、仪器分析技术(流动分析、色谱、毛细管电泳、原子发射光谱、电极法)在土壤养分分析中的应用和土壤采样和分析自动化的发展进行了回顾。总起来说,土壤养分分析的现代化已取得了相当大的进展,但是,在现有自动分析中,土样混匀和土壤含水量测定仍是土壤养分分析自动化中需要深入研究的问题,可能的解决途径是在适当降低分析结果的准确性上追求较快的分析速度。

| Abstract: | Development of agriculture and the need for better environment require more soil samples being analyzed in shorter time for soil nutrient information, as a result, modernization of soil nutrient analysis is the way we must choose. This paper reviewed progress in application of universal extractants (such as AB-DTPA, 0.5 mol/L sodium bicarbonate, 0.01 mol/L calcium chloride, Kelowna, strontium-citric acid solution and water), application of instrumental analysis (such as flow analysis, capillary electrophoresis, liquid chromatography, atomic emission spectrometry and electrode) for soil nutrient analysis, and automation of soil sample collection and analysis in the last 20 years. However, mixing of soil sample and soil moisture determination are still two problems in the automation of soil nutrient analysis. To compromise between the analysis speed and the accuracy is recommended as the solution. |
