Description

A method for preparing high-efficiency compound fertilizer for fruit trees by using red mud

technical field

The invention relates to a method for preparing high-efficiency compound fertilizer for fruit trees by using red mud, which belongs to the field of agricultural technology.

Background technique

Red mud is the polluting waste slag discharged when the aluminum industry extracts alumina. Generally, for every ton of alumina produced, 1.0 to 2.0 tons of red mud are incidentally produced. As the world's fourth largest producer of alumina, China discharges millions of tons of red mud every year. A large amount of red mud cannot be fully and effectively utilized, and can only be stacked in a large area of storage yard, which occupies a large amount of land and causes serious pollution to the environment. The red mud produced in the world is about 70 million tons every year, and the red mud produced in my country is more than 30 million tons every year. The production of a large amount of red mud has caused direct and indirect impacts on human production and life in many aspects. Therefore, it is imminent to reduce the output and harm of red mud to the greatest extent and realize multi-channel and large-scale resource utilization.
