Abstract

The invention relates to a coal gangue bio-organic fertilizer for improving desertification land. The coal gangue is used as a substrate and a biological agent is added; the preparation method comprises the following steps: preparing the biological agent; the method comprises the following steps: crushing, drying, ball-milling and mixing coal gangue, and then adding a biological agent for aerobic fermentation; and mixing, balling, drying, metering and packaging. The biological agent is prepared through combined fermentation of a liquid fermentation tank and a solid fermentation tank. The biological agent is prepared through combined fermentation of the liquid fermentation tank and the solid fermentation tank which are intelligently controlled, the coal gangue serves as a matrix and a carrier, after the organic fertilizer added with the biological agent is applied to the desertification land, the pH value of the desertification land is reduced, plant growth is facilitated, heavy metal in the desertification land can be fixed through humic acid, and the fertility of the desertification land is improved. The organic fertilizer does not cause heavy metal pollution to the desertification land, greatly increases nitrogen, phosphorus and potassium, organic matters and other necessary elements required by plant growth in the desertification land, promotes growth and reproduction of microorganisms, and improves the quality and yield of crops.

Description

technical field [0001] The invention relates to the technical field of bio-organic fertilizers, more particularly, to a coal gangue bio-organic fertilizer for improving sandy land and a preparation method and application thereof. Background technique [0002] Coal gangue is the waste in the process of coal mining and washing, and it is one of the industrial solid wastes with the largest emission. Coal gangue accumulates for a long time, occupies cultivated land, pollutes water quality, and generates H after spontaneous combustion 2 S, S0 3 and other harmful gases, causing air pollution, which constitutes a double damage to the ecology and the environment. At the same time, coal gangue is a natural resource that can be exploited and utilized. Comprehensive utilization of coal gangue can not only reduce land pressure and improve environmental quality, but also optimize and adjust the industrial structure of enterprises and divert surplus personnel. [0003] The utilization ...
