Beneficial effect of the present invention:
Mineral sources semicoke charcoal soil conditioner of the present invention, mineral sources semicoke charcoal can absorb and the heavy metal in passivation soil, the ventilation property increasing soil, the water-retentivity increasing soil and nutrient preserving capability etc.Be equipped with auxiliary material calcium again, magnesium, Si oxide can nurse one's health different acid soils and repair, progressively improve the fertility of soil, improve the Quality and yield of crop, reach environmental and ecological object; And oil shale source is extremely extensive, most of producing coal area all has the raw material that can make semicoke charcoal to its pyrolysis, and that have or even as mine waste processes, and the regional annual production had just has millions of ton.
The preparation method of mineral sources semicoke charcoal soil conditioner of the present invention, mineral substance or biomass are heated in the absence of oxygen and carries out pyrolysis, oil shale semicoke charcoal is produced after relevant fugitive constituent is suggested, this oil shale semicoke charcoal be raw material oil shale after heat treatment, all bacteriums, virus are all killed by high temperature, soil are had to the effect of sterilization and disinfection simultaneously; Can absorb and the heavy metal in passivation soil, the ventilation property increasing soil, the water-retentivity increasing soil and nutrient preserving capability etc., preparation method is simple, and tooling cost is low.
Accompanying drawing explanation
Fig. 1 is scanning electronic microscope (SEM) figure that oil shale amplifies 10000 times;
Fig. 2 is scanning electronic microscope (SEM) figure that oil shale semicoke charcoal prepared by the present invention amplifies 10000 times.
Below in conjunction with specific embodiment and accompanying drawing, the invention will be further described.
Embodiment
A kind of mineral sources semicoke charcoal soil conditioner, be prepared from by following raw material: oil shale semicoke charcoal and auxiliary material, described auxiliary material is for changing calcium, magnesium oxide and Si oxide, the weight ratio of described oil shale semicoke charcoal and described auxiliary material is 6:4, the weight ratio of described calcium oxide, magnesium oxide and Si oxide is: 1.5:1:1.5, and described oil shale semicoke charcoal is prepared from through Overheating Treatment by raw material oil shale.
The preparation method of the mineral sources semicoke charcoal soil conditioner described in the present embodiment, comprises the following steps:
