Problems solved by technology

[0002] At present, desert control, water and soil erosion, rocky desertification control, and improvement of the ecological environment are an important task for human beings. In some places, water and soil erosion is serious, desertification, and rocky desertification are serious, which affects the ecology and causes the natural environment to deteriorate and cause heavy losses. Steel slag is used as metallurgical solid waste material, which pollutes the environment and takes up space for stacking

Embodiment 1

[0021] Add steel slag powder, bone meal, plant debris, and soil particles to the same weight of water in a ratio of 5:2:1:2 to make a slurry, then add a certain amount of grass seeds, and cover the desert with 200mm thick mixed and solidified porous soil layer.

Embodiment 2

[0023] Steel slag powder, bone meal, inorganic fertilizers, organic plant debris, and soil particles are mixed in a ratio of 4:2:2:2, and the same weight of water is added to form a slurry, and a certain amount of grass seeds are added to form a slurry in the karst rock layer. Overlay 100mm of mixed and solidified porous soil layer.

Embodiment 3

[0025] Steel slag powder, bone meal, soil particles, organic plant debris and other materials, according to the ratio of 4:3:2:1, then add the same weight of water, mix into mud, and pave 100-200mm thick on both sides of the desert road. The 50-meter-wide mixed and solidified porous soil layer is perforated to plant tamarisk and other desert plants to prevent and fix sand, which is conducive to the long-term growth of tamarisk and other desert plants.

Abstract

The invention provides a material capable of controlling desertification (rocky desertification) and a preparation method thereof. The self-solidification characteristics and the chemical fertilizer characteristics of metallurgical solid waste steel slags are utilized; the material is mainly prepared by crushing or granulating and mixing the metallurgical solid waste steel slags, bone meal, plantdebris and other garbage; the material can achieve the effects of facilitating plant growth and fixing sand and stones; the material has the effect of long-acting chemical fertilizer; plant seeds or young plants can be planted in the material to take the effect of greening desert or stony desert; and the selected preparation materials are the metallurgical solid waste steel slags, so that the pollution to the environment can be reduced by waste utilization.

Description

technical field [0001] The invention relates to a material for controlling desertification (rocky desertification) and a preparation method thereof. Background technique [0002] At present, desert control, water and soil erosion, rocky desertification control, and improvement of the ecological environment are an important task for human beings. In some places, water and soil erosion is serious, desertification, and rocky desertification are serious, which affects the ecology and causes the natural environment to deteriorate and cause heavy losses. As metallurgical solid waste material, steel slag pollutes the environment and takes up space for stacking. Contents of the invention [0003] The purpose of the present invention is to utilize the self-adhesiveness of steel slag to bond bone meal, clay particles, and plant debris. Steel slag contains multiple elements and can be used as a fertilizer for plant growth, thereby forming a mixed and solidified porous soil layer that...
