Description

Method and product for producing special fertilizer for controlling sand by using high silicon iron tailings

Technical field

The invention relates to a method and a product for producing special fertilizer for controlling sand by using high silicon iron tailings.

Background technique

Desertification refers to arid and semi-arid areas. The destruction of ecosystems due to natural factors and human activities has led to changes in the desert-like environment. In arid and sub-arid areas, in the case of arid and windy winds and loose sandy grounds, due to unreasonable economic activities of human beings, the areas of the original non-sand deserts have been characterized by sandstorm activities and dune fluctuations. An environmental degradation process similar to a desert landscape. Desertification is a phenomenon of environmental degradation, a process that gradually leads to a decline in biological productivity, including the three stages of occurrence, development and formation. The occurrence phase (initial phase) is a potential desertification. There are only basic conditions for desertification, such as dry climate, surface vegetation begins to be destroyed, and a small area of loose drifting sand is formed. At the development stage, the ground vegetation begins to be destroyed and wind erosion occurs. Surface roughening, speckled quicksand and low shrub sand dunes, with the increase of sandstorm activity, there are further moving sand dunes or blown shrub sand dunes; in the formation stage, densely distributed mobile sand dunes or blowing are widely distributed on the surface. Shrub sand piles, whose area accounts for more than 50% of the land area.
