Abstract

The invention relates to a method for degrading weathered coal with a gamma ray. At present, the development of water-soluble coal-based acid has fallen behind the production requirement and the development of new manure technology suitable for industrial production becomes urgent to meet the constantly expanded market demands. The method comprises the following step: the macromolecules in the weathered coal are degraded to water soluble micromolecules by radiating the weathered coal with the gamma ray, wherein the gamma ray is the radioisotope cobalt-60, with total dose of 50-200kGy. The method is used for degrading the weathered coal.

Description

Technical field: [0001] The invention belongs to the technical field of agriculture and is applied to the production of humic acid liquid fertilizer, in particular to a gamma ray degrading weathered coal technology. Background technique: [0002] In recent years, the total amount of chemical fertilizers in my country has increased by 90.7%, while the total amount of grain has only increased by 9.1%, and the loss rate of nitrogen fertilizers is as high as 65%, which has caused serious environmental pollution, and the situation of unreasonable use of chemical fertilizers has become increasingly prominent. According to reports, one-fifth of the arable land in my country is polluted by heavy metals, organic pollutants, and agricultural chemicals. These pollutions have led to a decline in the quality and output of agricultural products, causing at least tens of billions of direct economic losses every year. Soil pollution has already Our country's environmental quality, food safet...
