FIELD: agriculture.
SUBSTANCE: organic-inorganic polymer water-retaining fertilizer is a copolymer which is mainly obtained by combining and copolymerising an organic water-retaining monomer and an inorganic nutrient under the effect of a catalyst, a biological enzyme and a modifying reagent, a water-retaining polymer, an inorganic nutrient and a biological enzyme are chemically bonded in an organic-inorganic polymer water-retaining fertilizer, and said copolymer has a three-dimensional mesh-like hydrophilic group-containing structure. Disclosed is a method of producing organic-inorganic polymer water-retaining fertilizer.
EFFECT: inventions provide simultaneous delayed release, as well as regulation of release and water, and fertilizer, resistance to pests and diseases, regulation of soil condition.
