Abstract:
The present invention provides an organic-inorganic polymeric water-retaining fertilizer. The organic-inorganic polymeric water-retaining fertilizer is a co-polymer made by fusion and co-polymerization of an organic water-retaining monomer and an inorganic nutrient under action of a catalyst, a biological enzyme and a modifying agent. The co-polymer is of a three-dimensional mesh-like hydrophilic group structure. In a method for preparing the organic-inorganic polymeric water-retaining fertilizer, after obtaining a neutralized pre-polymer from the organic water-retaining monomer under the action of the catalyst, an initiator and a cross-linking agent are added; the inorganic nutrient and a metasilicate are added simultaneously, a solution is formed by stirring sufficiently; the biological enzyme is added for catalysis; a co-polymer is obtained after fusion and co-polymerization; and granulation and drying are carried out. Preferably, the catalyst is an inorganic alkaline solution. Preferably, the catalyst is selected from the group consisting of a sodium hydroxide solution, a potassium hydroxide solution, an ammonia water and a calcium hydroxide solution.

Claim (Index 3):
The organic-inorganic polymeric water-retaining fertilizer according to  claim 1 , wherein said inorganic nutrient comprises one or more selected from the group consisting of calcium magnesium nitrate, urea, monoammonium phosphate, potassium salt, calcium nitrate, magnesium sulfate, zinc sulfate, sodium silicate and sodium borate; and preferably, said potassium salt comprises one selected from the group consisting of a potassium sulfate and a potassium chloride.
