Background technique
As Chinese Industrialization, Development of China's Urbanization quickly propel, heavy metal pollution of soil becomes increasingly conspicuous, chemical industry, mining, smelting
Industrial " three Waste "s, urban transportation, atmospheric sedimentation, feces of livestock and poultry, municipal sludge, the agriculture chemicals such as refining etc. become primary pollution source.
Since agricultural land soil is by heavy metal pollution, the agricultural product heavy metal pollution problem produced on contaminated farmland becomes increasingly conspicuous.In
State's heavy metal content in soil has been more than that soil background, especially Cd and Pb are seriously polluted.
Traditional research method is that the chemical substances such as white lime, calcium silicates are added into soil, by the way that these substances are added,
The series reactions such as precipitating, absorption, ion exchange, humification and redox can occur with heavy metal element, significantly reduce
Its biological effectiveness and transportable property, hence it is evident that slow down toxic action of the heavy metal pollution to plant growth, plant pair is greatly decreased
The absorption and accumulation of heavy metal, still, these substances are inorganic substances mostly, influence soil physical chemistry property and fertility, right
Microorganism growing environment causes different degrees of influence, also influence repair after the completion of soil using degree, it is also possible to produce
Raw secondary pollution, we have devised a kind of natural medical stone agricultural soil heavy metal deactivator and preparation method thereof and come thus
Solve problem above.
