硅钼蓝比色法测定石灰性土壤有效硅的方法及控制技术

Method and Control Technology for Determination of Available Silicon in Calcareous Soil by Silicon Molybdenum Blue Colorimetric Method

测定土壤中的有效硅含量可及时了解土壤硅素肥力的状况,对指导施肥、改良土壤、提高产量、保护环境具有重要意义。本文探讨了石灰性土壤有效硅含量的检测方法和控制技术,以期对正确地评价保护地土壤的供硅能力以及测土配方施肥提供指导。

The status of soil silicon fertility can be known by determination of available silicon content in soil, which is of great significance for guiding fertilization, improving soil, increasing yield and protecting environment. In this paper, the detection methods and control technology of available silicon content in calcareous soil were discussed, in order to provide guidance for correctly evaluating the silicon supplying ability of soil in protected land and formula fertilization by soil testing.
