Studies of Available Silica Content in the Soils of Fujian Province and the Prerequisite for its Variation

摘要: 对福建省耕地和非耕地主要土类179个样品的分析和室内模拟试验结果:80%供测土样、83.7%的稻田土样,其土壤有效硅含量均在临界值以下。并探讨了土壤有效硅含量与土壤母质、pH值、耕作、施肥条件的关系。指出:福建省是个土壤缺硅省份,科学开发和利用硅肥是一项重要的农业措施。

Abstract: This paper summarized the available silica(SiO2)content in the major soil types of Fujian province on the basis of analysing 179 soil samples from both cultivated and uncultivated land and indoor simulant experiments, the results demonstrated that there is silica deficiency in the soil of Fujian province and the variation of available silica content in soil has a close relationship with the condition of soil matrix,pH,farming system and fertilizer application. It is also suggested that exploitation and application of silica fertilizer is an important measure to sustainable agriculture.
