Abstract

The invention discloses a method for producing liquid complexing fertilizer containing nickel and belongs to the field of the chemical industry. The fertilizer is mainly prepared from the following materials in parts by weight: 30-40 parts of urea, 10-20 parts of ammonium phosphate, 10-20 parts of fulvic acid, 8-15 parts of monosodium glutamate protein, 5-15 parts of sylvite, 1-2 parts of zinc sulfate, 1.5-2.5 parts of boric acid, 2.5-3.5 parts of ferrous sulfate, 5-8 parts of magnesium sulfate, 2-3 parts of manganese sulfate, 2-3 parts of copper sulfate and 2-3 parts of nickel sulfate. The liquid complexing fertilizer containing nickel is prepared from the materials by complex reaction, concentration, sanding and bulking processes. The fertilizer is high in complex degree, good in fertilizer efficiency and lasting in fertilizer efficiency, is quick-acting, can effectively avoid hardening of the soil, and can be applied to crops such as cotton, wheat, garlic and the like.

Description

technical field [0001] The invention relates to a production method of a complex fertilizer, in particular to a production method of a nickel-containing liquid complex fertilizer, which belongs to the field of chemical industry. Background technique [0002] The complex is a ring structure formed by connecting a macromolecular ligand with a central metal atom. Organic molecular compounds capable of complexing with metal ions are called complexing agents, or ligands. Complexing agents can selectively capture certain metal ions in the cells of plants, and release the metal ions in an appropriate amount when necessary. Since the complexing agent has the ability to "capture" (swallow or capture) and "manipulate" (spit or release) metal ions, it makes it easier and more reasonable for crops to absorb nutrients, so it assumes the role of the command center in plants. Function, balance the nutrient supply between roots, stems, leaves, flowers, and fruits, so that plants can grow ...
