Abstract
The invention provides an organic-inorganic polymerizationwater retentionfertilizer. The organic-inorganic polymerizationwater retentionfertilizer is a copolymer formed by fusing and copolymerizing organic water retention monomers and inorganic nutrients under the action of a catalyst, biological enzymes and a modifying agent, and the copolymer has a three-dimensional netty hydrophilic group structure. A preparation method of the organic-inorganic polymerization water retention fertilizer comprises the steps that after a neutralized prepolymer is obtained through the organic monomers under the action of the catalyst, an initiator and a cross-linking agent are added, meanwhile, the inorganic nutrients and metasilicate are added, a solution is formed through full stirring, the biological enzymes are added for catalyzing, the copolymer is obtained after fusion and copolymerization, and pelleting and drying are carried out. Preferably, the catalyst is an inorganic alkaline solution. Preferably, the catalyst is selected from a sodiumhydroxide solution, a potassiumhydroxide solution, ammonia water and a calciumhydroxide solution.
Description
technical field [0001] The invention relates to the field of fertilizers, in particular to an organic-inorganic polymeric water-retaining fertilizer and a preparation method thereof. Background technique [0002] The preparation method of an organic-inorganic polymer water-retaining fertilizer of the present invention is a method of fusion and copolymerization of a polymer water-absorbing resin and an inorganic nutrient factor, so that it has the functions of water and fertilizer in one body - water and fertilizer preservation, slow release synchronization - double controlled release of water and fertilizer New water-retaining fertilizer materials with functions such as anti-disease and insect pests and soil conditioning functions. [0003] Its technical indicators: organic matter content ≥ 20%; water absorption multiple 10g / g-20g / g; total nutrients of nitrogen, phosphorus and potassium 35%-40%; total nutrients of calcium, magnesium, silicon and sulfur ≥ 5%; The nutrient re...
