Three-dimensional silicon carbon soil conditioner

Abstract

The invention discloses a three-dimensional silicon carbon soil conditioner which is composed of, by weight, 25-35% of sodium-type zeolite powder, 25-35% of calcium-type zeolite powder, 10-15 parts ofmedical stone, 10-15% of diatomite and 10-15% of hexacyclic stone. A preparation method of the soil conditioner includes: sufficiently mixing the above materials, grinding to 300 meshes, calcining athigh temperature of 400 DEG C for 2h, cooling, and packaging for use. The soil conditioner is formed by processing and activating high-quality natural minerals, belongs to activated-carbon-like porous substances, is rich in various trace elements, has functions of adsorption, exchange, catalysis and curing after being processed and activated, has obvious adsorption and exchange effect on variousheavy metal ions, ammoniacal nitrogen, nitrite and sulfide, has good effect and can reduce and prevent soil pollution and maintain a stable state of soil for a long time after heavy metals in the soilare eliminated.

Description

technical field [0001] The invention relates to a soil quality conditioner, in particular to a three-dimensional silicon carbon soil conditioner. Background technique [0002] With the continuous development of economy and society, the acceleration of human activities and social industrialization, the problems of soil pollution and soil degradation have become increasingly prominent worldwide. Soil pollution, most of which come from industrial pollution, domestic pollution, chemical fertilizers, pesticides, etc. Pollutants are mainly cadmium, lead, mercury, fluorine, ammonia nitrogen, sulfide, arsenic, phenolic compounds, organic phosphorus emissions, etc. Soil degradation manifests as soil fertility impoverishment, salinization, and heavy metal pollution. The problems of soil pollution and soil degradation are becoming more and more serious, which have caused great harm to the ecological environment, and at the same time, have also produced toxic effects on the human body....

AI Technical Summary

Problems solved by technology

The problem of soil pollution and soil degradation is becoming more and more serious, which has caused great harm to the ecological environment, and at the same time, it has also produced toxic effects on the human body

Large-scale land salinization and excessive heavy metals have seriously affected the growth of crops, severely restricted the development of land productivity, increased the cost of agricultural production, and affected the yield and quality of crops

Aiming at the control of soil pollution and soil degradation, people currently use some soil conditioners, which have played a certain role in improving soil pollution and soil degradation. However, due to the large amount of chemical components in the conditioner, improper use is easy to cause secondary damage to the soil. Pollution, not conducive to popularization and application
