Environmental-protection magnetic fertilizer and preparation process thereof

Abstract

The present invention provides an environmental-protection magnetic fertilizer and a preparation process thereof, wherein the environmental-protection magnetic fertilizer is characterized by further containing a magnetic substance, wherein a mass ratio of the magnetic substance to the chemical fertilizer is 0.5-7:100, and the magnetic material is selected from a natural magnetic mineral such as magnetite, maghemite and the like, and an artificial permanent magnet magnetic material such as an iron oxide magnetic material, an iron-manganese permanent magnet material and a rare earth permanent magnet material. The magnetic fertilizer production method comprises: (1) weighing a certain amount of a common chemical fertilizer, and mixing with a magnetic substance according to a predetermined ratio; (2) uniformly stirring; and (3) placing the uniformly-stirred mixture into a magnetic field to carry out a magnetization treatment so as to obtain the final product. According to the present invention, the food yield can be significantly improved while the nitrogen consumption can be reduced so as to pollution of agricultural production on the environment; and the magnetic fertilizer can be conveniently produced through the method.

Description

technical field [0001] The invention belongs to the field of agricultural chemical fertilizers, and in particular relates to an environment-friendly magnetic chemical fertilizer and a preparation process thereof. Background technique [0002] With the development of large-scale agricultural production and the improvement of human requirements for the environment, the contradiction between increasing fertilization to increase production and reducing non-point source pollution (especially N and P pollution) caused by agricultural production has become increasingly prominent, so further development of new Fertilizers, so that new fertilizers that do not reduce their yield while reducing the amount of fertilizer applied are imperative. [0003] At present, in agricultural production, the application of organic fertilizers is declining sharply, while the application of chemical fertilizers (especially chemical nitrogen fertilizers) is increasing, which not only greatly increases ...

AI Technical Summary

Problems solved by technology

[0003] At present, in agricultural production, the application of organic fertilizers is declining sharply, while the use of chemical fertilizers (especially chemical nitrogen fertilizers) is increasing, which not only greatly increases the cost of agriculture, but also leads to the deterioration of the water environment and atmospheric environment.
