A kind of coal base biological soil that is used for substitution tables soil that the present invention proposes, it is characterized in that, mainly mix by weathered coal, flyash, coal gangue, wilkinite, water-holding agent and soil stabilizer, the weight percent of each composition is weathered coal 30-60%, flyash 8-40%, coal gangue 10-40%, wilkinite 1-10%, water-holding agent 0.1-1%, soil stabilizer 0.1-1%.
The another kind that the present invention proposes is used for the coal base biological soil of substitution tables soil, mainly mix by weathered coal, flyash, the peat composed of rotten mosses, wilkinite, water-holding agent and soil stabilizer, the weight percent of each composition is weathered coal 30-60%, flyash 8-40%, peat composed of rotten mosses 10%-30%, wilkinite 1-10%, water-holding agent 0.1-1%, soil stabilizer 0.1-1%.
Characteristics of the present invention and technique effect:
" coal base biological soil " that the present invention develops has the fundamental characteristics of soil, be that a kind of ecology (plant) is recovered and the proprietary material of rebuilding, have water conservation, fix the sand, promote Revegetation and improve the effect of vegetation output, essential nutrient contents, organic matter, water retention property etc. all reach the autochthonous soil level in the product, and wherein organic content is more than 30%.Can promote the to reclaim vegetation growth of soil or deteriorate grassland, desertify or the soil of newly-ploughed vegetation rareness on can increase grass yield; Promote the recovery of deteriorate grassland vegetation.
" coal base biological soil " mainly based on coal gangue, weathered coal, flyash and the peat composed of rotten mosses, weathered coal is a kind of low-rank coal, and is very abundant in China especially the Northwest's reserves, however its not burning value.The peat composed of rotten mosses is the plant remains in the palustrine of the face of land, under atmosphericoxygen and action of microorganisms, forms the combination of organism and soil ulmin.Coal gangue is the solid waste that produces in the coal mining process, and its stacking has taken a large amount of farmlands and also polluted environment.Flyash is collected a kind of industrial residue from the coal firing boiler gas of fuel-burning power plant, and its storage not only will take a large amount of soils, and easily mining area atmosphere, water surrounding is polluted and destroy.These all are the wastes in mining area, and land occupation utilizes these wastes as the native equivalent material of table, can reduce the area that covers the soil on the one hand, can also turn waste into wealth on the other hand, makes solid waste resource recovery and reduces it to environment damage.
This is shown native equivalent material and is rich in trace elements such as organic matter and biological essential zinc, boron, molybdenum, field and pot experiment show, do not execute or apply slightly fertilizer growing plants in this material and all be better than or be equal to growing plants on the control soil, thereby reached the native alternate purpose of table.By to being grown in the mensuration that plant on this matrix carries out heavy metal content, find that heavy metal content in the plant all less than state specified standards, therefore can be described as the material of a kind of " cleaning ", can not have a negative impact to environment.
