Soil remediation agent and preparation method thereof

Abstract

The invention discloses a soil remediation agent. The soil remediation agent is prepared from the following components in parts by mass: 10 to 20 parts of cow dung, 10 to 20 parts of sheep manure, 10to 20 parts of straws, 10 to 20 parts of vinasse, 10 to 15 parts of calcium superphosphate, 1 to 5 parts of molasses, 5 to 10 parts of humic acid, 1 to 5 parts of bacillus, 1 to 5 parts of lactic acidbacteria, 1 to 5 parts of zymophyte, 1 to 5 parts of photosynthetic bacteria and 10 to 20 parts of one or a combination of shell powder and oyster powder. The soil remediation agent disclosed by theinvention has the beneficial effects that (1) by reusing the cow dung and the sheep manure and wastes such as the straws, the circular economy is promoted, and remediation of soil is also completed; (2) by adding one or the combination of the shell powder and the oyster powder, mineral substances in the soil are effectively supplemented, so that the mobility of heavy metals is effectively reduced,and the concentration of heavy metal ions in the soil is obviously reduced; (3) by adding the molasses, the humic acid and the vinasse, reproduction and metabolism of microorganisms are promoted, theeffects of the microorganisms are strengthened, and degradation of organic pollutants by the microorganisms is promoted.

Description

technical field [0001] The invention relates to the field of soil restoration, in particular to a soil restoration agent and a preparation method thereof. Background technique [0002] With the development of industry and agriculture and the improvement of people's living standards, waste water and solid waste discharged in industrial production, pesticides used in farmland, and waste in people's daily life have increasingly polluted the soil, causing soil pollution. Structural damage, soil compaction, and heavy metals exceeding the standard. When the soil contains too many harmful substances and exceeds the self-purification capacity of the soil, the composition, structure and function of the soil will change, microbial activities will be inhibited, and harmful substances or their decomposition products will be in the soil. Gradually accumulate in the human body through "soil → plant → human body", or indirectly absorbed by the human body through "soil → water → human body"...

Problems solved by technology

However, the existing methods not only have high cost, but also take a long time to repair the soil, and the repair effect is not ideal; at the same time, some chemical preparations will cause secondary pollution to the soil
