| description | The invention provides a tailing pond soil biochar improvement method and system based on pollution sweep calculation, and belongs to the field of biological informatization agriculture. The heavy metal content and the pH value of soil at each sampling point are collected before rainfall, and the rainfall capacity at each sampling point is recorded during rainfall; the heavy metal content and the acid-base value of soil at each sampling point are collected after rainfall, and the application proportion distribution of the biochar composite modifier at each sampling point is calculated according to the heavy metal content and the acid-base value of soil at each sampling point before and after rainfall in combination with the rainfall capacity at each sampling point, so that acid production of ore soil is inhibited, and the utilization rate of the biochar composite modifier is improved. Heavy metal pollution is controlled, so that the soil nutrition structure is improved, the soil fertility is improved, and veg |
