Description
Technical field
The present invention relates to fixed-end forces field, soilless culture field, specifically a kind of copper tailing barren rock soilless culture substrate
And preparation method thereof.
Background technology
Discarded object after mine tailing category ore dressing, it is the chief component of industrial solid castoff.It is all to have mineral resources and enter
The country of row ore dressing processing has substantial amounts of mine tailing to produce.With developing rapidly for industry, mine tailing is in industrial solid castoff
The ratio accounted for is also increasing.
The generation of barren rock is mainly stripping country rock link of the mine in recovery process.China's chats discharge capacity is suitable
Greatly, this it is not only serious have influence on making full use of for mineral resources, while serious harm is also caused to environment, such as barren rock
Accumulation not only occupied substantial amounts of farmland and soil, and heavy damage, water body are contaminated to soil reclamation.In addition, heap
Long-pending barren rock easily forms the landslide that caves in because the gradient is excessive, or even produces the geological disasters such as mud-rock flow, cause neighbouring soil to be buried,
Building is ruined, and seriously jeopardizes the safety of the masses around.
At present, the research comprehensively utilized to copper tailing and barren rock is more, and to copper tailing and barren rock whole utilization in preparation
The research of soilless culture substrate is less.At present, the report about this respect is not seen also.
The content of the invention
It is existing to solve it is an object of the invention to provide a kind of copper tailing barren rock soilless culture substrate and preparation method thereof
The problem of copper tailing barren rock is accumulated and pollutes environment, land occupation in technology.
The technical proposal of the invention is realized in this way：
A kind of copper tailing barren rock soilless culture substrate and preparation method thereof, comprises the following steps：
（1）Copper mine barren rock is crushed, obtains granularity 0.5 ~ 4.75mm particulate barren rocks；
（2）By step（1）Particulate barren rock is uniformly laid in cultivation bed, 3 ~ 5cm of thickness；
（3）One layer of woven bag is covered on particulate barren rock；
（4）To uniformly it be laid in groove on woven bag without native copper tailing matrix, 10 ~ 15cm of thickness；
（5）By 80 ' 100 times of s Special heavy metal microorganism remediations dilution agents, it is sprayed above the matrix in groove, 80 ' s
Special dosages are 3 ~ 6 ml/m2；
（6）Into groove plus water is irrigated, and reclaims irrigation water, by the water of recovery into groove cyclic irrigation, until matrix weight in groove
Tenor meets standard.
Further, the step（1）Particulate barren rock modulus of fineness is 3.4 ~ 3.6.
Further, the step（4）It is according to percetage by weight by following each component without native copper tailing matrix：Copper tailing
30% ~ 40%, leaf mould 40% ~ 50%, loose squama 3% ~ 5%, perlite 3% ~ 5%, medical stone 3% ~ 5%, decomposed manure 6% ~ 10% are abundant
It is well mixed, bank up curing and be made for 5 ~ 8 days.
Further, the copper tailing modulus of fineness 2.0.
Further, the loose squama granularity is 40 ~ 60 mesh.
Further, the perlite granularity is 60 ~ 80 mesh.
Further, the medical stone granularity is 60 ~ 80 mesh.
Further, it is described banked up without native copper tailing matrix during, remain the moisture of material for 40% ~
50%。
Further, the step（5）80 ' s Special are the heavy-metal contaminated soil liquid of the international production in U.S. forward position
State microorganism renovation agent, heavy metal can be neutralized, improve matrix organic content, increase matrix fertility, promote plant growth.
Beneficial effects of the present invention are：
