Magnetic fertilizer and production method thereof

Abstract

The invention relates to a magnetic fertilizer and a production method thereof. The magnetic fertilizer consists of chemical fertilizer, and is characterized by also comprising a magnetic substance, wherein mass ratio of the magnetic substance to the chemical fertilizer is between 0.1-5:100. The magnetic substance is selected from natural magnetic mineral, such as magnetite, maghemite and the like, and artificial permanent magnetic material, such as iron oxidization magnetic material, ferrimanganic permanent magnetic material or rear-earth permanent magnetic material. The production method for the magnetic fertilizer comprises the following steps: (1) firstly weighing a certain amount of common chemical fertilizer, and then mixing the common chemical fertilizer and the magnetic substance in a preset proportion; (2) stirring the mixture evenly; and (3) putting the evenly stirred mixture in magnetic field, and carrying out magnetization treatment on the mixture to obtain final products. The production method can improve the yield of grains remarkably, and reduce application amount of nitrogen at the same time, so as to reduce pollution of farm production to environment. The production method can conveniently produce the magnetic fertilizer.

Description

technical field [0001] The invention relates to a chemical fertilizer and a production method thereof, in particular to a magnetic chemical fertilizer and a production method of the chemical fertilizer. 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 decreasing sharply, while the application of chemical fertilizers (especially chemical nitrogen fertilizers) is increasing, which not only greatly increases the cost ...

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 the atmospheric environment.
