| 摘 要： | 本文综述了土壤供Si能力评价方法的研究历史与现状,比较了这些方法的优缺点。经典的1mol/L醋酸-醋酸钠(pH4.0)缓冲液提取法不适于评价pH较高土壤的供Si能力,以水或稀氯化钙溶液为提取剂的方法能够解决这一问题,但存在繁琐、费时等缺点。围绕着建立评价广泛pH范围土壤供Si能力的通用方法开展相关研究将是今后的重点。

| Abstract: | The history and present status of studies involved in evaluation methods of soil silicon supplying capacity are reviewed and the merits and demerits of these methods are compared in this paper. The traditionally used 1 mol/L HAc-NaAc(pH 4.0)buffer solution method is inappropriate to evaluate silicon supplying capacity of soils with high pH values. The methods with water or dilute CaCl2 solution can be used to evaluate the soil silicon supplying capacity. However, these methods are trivial and time-consuming. It deserves further study to explore a universal method to evaluate the silicon supplying capacity of soils within a wide pH value range. |
