Abstract:
     The present invention relates to a fertilizer containing soluble silicon and plant-growth regulator. Said fertilizer contains effective SiO2 21.5-29.0%, in which water soluble SiO2 is 4.1-6.5%, P2O5 1-3% and water content 0.5-less than 7%, and contains the components contained in yellow phosphorus slag. Its preparation method includes the following steps: pulverizing the dewatered and impurity-removed yellow phosphorus slag, screening to make 55-80% of slag powder pass through 100 meshes, adding water-soluble silicate and uniformly mixing them to make the water soluble SiO2 content reach to 4.1-6.5%. Said invented product can make crops of rice, etc. Vegetable and fruit, etc. increase in yield, and its preparation process is simple and cost is low.
