Recently, experts from the Agricultural Branch of the China Association of Old Scientific and Technical Workers organized experts to evaluate the scientific and technological achievements of the "Silicon Organic Fertilizer Technology for the Control of Saline-Alkali Soils" project jointly completed by the Hebei Silicon Valley Agricultural Research Institute and Hebei Silicon Valley Fertilizer Co., Ltd.


The evaluation expert group watched the project test demonstration on site, heard the report of the completed unit's results, and discussed the project content. In the end, the expert group agreed that the organic silicon functional fertilizer formed by organic silicon materials and compound fertilizers has multiple functions of improving saline-alkali soil and supplementing nutrient elements, and created a set of technical systems for the improvement and management of saline-alkali land in China. A breakthrough in soil governance. The research and development of organic silicon functional fertilizer and product application technology have reached the international advanced level of similar research, and have reached the international advanced level in the improvement technology of saline-alkali land. It is recommended to promote the application in different types of saline-alkali regions in the country.


It is reported that the research and development of the organic silicon functional fertilizer obtained 3 invention patents. Since 2017, multiple rounds of tests have been conducted in five major regions in Inner Mongolia, Jilin, Tianjin and Heilongjiang for more than two years. The area of saline-alkali soil improvement and promotion has been 6.65 million mu. The average reduction in salt volume was significant, and the benefits of creating output value exceeded 1.9 billion yuan, achieving great economic, social, and ecological benefits.
