Abstract
The invention discloses a multi-element water soluble liquid fertilizer, which is characterized by being prepared from the following raw materials in parts by weight: 10-32.0 parts of urea, 7.6-19.9 parts of phosphoric acid, 1.0-1.2 parts of boric acid, 0.4-1.3 parts of sodium molybdate, 40.0-55.0 parts of dipotassium phosphate, 6.4-9.3 parts of fulvic acid and 0.1-0.2 part of wood vinegar. The preparation method adopts the urea, the phosphoric acid and the dipotassium phosphate as main raw materials; in the prepared multi-element water soluble liquid fertilizer, P2O5 is more than or equal to K2O in amount; the boric acid and the sodium molybdate are taken as trace elements, and the soluble fulvic acid serves as a chelating agent; moreover, by adding the wood vinegar to a hydrosolvent, water molecule hydrogen bonds are cut off to form a cluster of 5 water molecules, thus greatly enhancing solubility and permeability of the hydrosolvent, and the fertilizer can be used as such multifunctional additives as a wetting agent. Besides advantages of a common multi-element water soluble liquid fertilizer, the fertilizer can also meet a demand of planting rice on improved saline land. Such soluble nutrients as N, P, K<+>, Mg<2+> and Ca<2+> can be provided to meet a demand of rice growth, so that growth of rice on the saline land is vigorous.
