| abstract |
The invention discloses a combined water-soluble fertilizer, which relates to the technical field of chemical fertilizer preparation, and comprises, in mass percentage, plant immune protein 3-4, trace elements 16-20, medium elements 13-17, macroelements and auxiliaries. A large number of elements include amino acid 20-28, potassium dihydrogen phosphate 8-16 and dipotassium hydrogen phosphate 8-16; the auxiliary agent includes dispersant 6-8, penetrant 6-8 and diluent 4-6; The macro elements are calcium salts; the trace elements include boron salts and zinc salts. The invention also discloses a preparation method of the above-mentioned combined water-soluble fertilizer. Through scientific compatibility of plant immune protein and medium and trace elements, the invention can fully ionize metal ions in inorganic salts with the help of a phosphate buffer system, and the ionized metal ions can be activated and combined by plant immune proteins to become organic components, which can be better utilized by crops. |
