Abstract
The invention discloses an improved tailings soil matrix. The improved tailings soil matrix comprises the following components in parts by weight as follows: 3.5-6 parts of granite, 3-6 parts of basalt, 4-8 parts of quartzite, 2-6 parts of shale, 1.8-4 parts of red sandstone, 4-6.5 parts of river mud, 2-5 parts of turf soil,1-3 parts of bog soil, 2-6 parts of pine needle mulch, 3.5-6 parts of humus, 4-7 parts of peat, 1.5-4 parts of acetic acid, 3-8 parts of coppernitrate, 0.8-1.8 parts of ferricnitrate, 0.6-1.5 parts of calciumnitrate, 0.5-1.2 parts of calciumphosphate, 1-2 parts of magnesiumphosphate, 2-4 parts of sodiumphosphate, 4.5-5.5 parts of mycorrhizal fungi, 1.7-3 parts of streptomyces jingyangensis, 1.8-4 parts of bacillus coagulans and 1.5-2 parts of paecilomyces lilacinus. A natural, long-term effective and cheap microbial nutrient source is provided for tailings soil matrix remediation, and the nitrogen fixation capacity of plant root systems can be improved, so that the soil fertility is improved, more mineral elements are added, the soil structure is effectively improved, more heavy metal elements can be cleared to precipitate, and the method is simple and worth popularizing.
Description
technical field [0001] The invention relates to the technical field of soil improvement, in particular to an improved tailings soil matrix and a preparation method thereof. Background technique [0002] The soil is originally a natural shelter and purification treatment place for various wastes. The soil accepts pollutants, which does not mean that the soil is polluted. Only when the soil contains too many pollutants, it affects and exceeds the self-purification ability of the soil. , thus producing harmful hygienic and epidemiological effects, which indicate that the soil has been polluted. There are many reasons for soil pollution, such as industrial sludge, agricultural garbage, sewageirrigation, pollutant deposition in the atmosphere, heavy use of mineral fertilizers and pesticides containing heavy metals, and so on. [0003] Soil matrix (Soil matrix) is a material composed of mineral and (or) organic particles less than 0.01 mm formed by the weathering and soil format...
