Method for preparing urea-clay mineral hybrid fertilizer

摘要

The invention physicochemical element applied to the soil as fertilizer and biochemical degradation dramatically improve the decrease in the fertilizer efficiency of the elements by, and at the same time the atmosphere by the NOx gas is generated according to rapid urease contamination and nitrate number of nitrogen environment stabilizes the components in order to sharply for water by the introduction of the the layers of the layered clay mineral at the molecular level, and at the same time fast-acting element to minimize the physicochemical and biochemical decomposition to reduce the maximum of the urea effective to provide a clay mineral fertilizers production method of de Hebrew - the number of elements in.; Elements of the present invention production process of the layered clay mineral is a plate-shaped clay mineral (inorganic salts + component) 1 by weight ratio, and from 0.5 to 2, the inorganic salts: the molar ratio of component 1 are mixed with 2-630 to a temperature of under 120 ℃ heat-treated for 0.5 to 4 hours and is cooled and consists in molding.
