The silicon-potash fertilizer comprises the following components in percentage by weight: 15-18% ofK2O, 5-10% of SiO2, 10-30% of an organic chelating agent and the balance of water, wherein the element K is derived from an inorganic compound of potassium; the element Si is derived from an inorganic compound of silicon; and the organic chelating agent is derived from an organic carboxylic acid. According to the organic liquid silicon-potash fertilizer disclosed by the invention, essential elements silicon and potassium of crops are subjected to equipotential chelating to form an organic chelate by virtue of a carboxyl compound and the like, and the chelate is excellent in water solubility,capable of being easily absorbed by crops, non-toxic, harmless, residue-free, low in cost and convenient to use. The fertilizer has the highest silicon content of 10% and the highest potassium contentof 20%, meets the national standard and can also meet needs of agricultural production. The preparation method of the fertilizer is low in energy consumption, simple in process low and environmentally friendly, and the product quality is easily controlled.
