Recently, the scientific and technological achievements of "Organic Functional Fertilizer Controlling Saline-Alkali Soil Technology" jointly completed by Hebei Silicon Valley Academy of Agricultural Sciences and Hebei Silicon Valley Fertilizer Co., Ltd. passed the evaluation of scientific and technological achievements organized by the Ministry of Agriculture and Rural Affairs in Beijing. The expert group agreed that organic silicon functional fertilizers have multiple functions of improving saline-alkali soil and supplementing nutritional elements, which can effectively promote the formation of soil aggregate structure and accelerate salt leaching; activate soil nutrients and improve the salt resistance of crops. Six series of products. This product development and product application technology has reached the international advanced level of similar research, and has reached the international advanced level in the improvement technology of saline-alkali land. It has explored a new way for the improvement and management of saline-alkali land in China, and opened the technological advancement of organic functional fertilizers for treating saline-alkali soil.
