Abstract

The invention relates to a coated slow release fertilizer, in particular to a production method of an organic-mineral material coated fertilizer. The invention solves the problems of selecting coating materials and determining process parameters of the coated fertilizer in the prior art. The coated slow release fertilizer consists of a fertilizer core and a coating material, and is characterized in that: the coating material uses mineral material, shellac and perchlorethylene, and the mineral material is any one or two or all of vermiculite, mica and zeolite. Generally speaking, the product obtained by the technical proposal has good slow-release property and can improve the utilization rate of fertilizer elements, reduce the environmental pollution and promote the growth of crops.

Description

technical field [0001] The invention relates to a coated slow-release fertilizer, in particular to an organic-mineral material coated fertilizer. Background technique [0002] Fertilizer is an important material basis for the development of agricultural production. The extensive use of chemical fertilizers has greatly promoted agricultural production and greatly improved the yield and quality of crops. But it also brings a series of negative effects at the same time, especially the problems of low fertilizer utilization rate, environmental pollution, and unbalanced composition structure. In long-term practice, scientific and technological personnel have invented a method of wrapping materials with specific properties on the outer layer of fertilizer particles with a binder to achieve controlled release of instant chemical fertilizers, so that the release of fertilizer nutrients and the absorption of crops can be synchronized. . This method is to reduce nutrient loss and is...
