Abstract
The invention discloses the modification method of a kind of gangue, including (1) breeding, April time, bimester after transplant, (2) coal gangue hill arranges, and keeps the slope of terrace-type slope banding, and (3) transplant, and (4) water management.The present invention is by planting Caulis Miscanthis floriduli on gangue, because Caulis Miscanthis floriduli can absorb heavy metal and well developed root system, the content of beary metal of gangue can be substantially reduced, reduce environmental pollution and the harm to human body, and can conserve water and soil, preventing landslide, its technological investment is few, the cycle is short, produce effects fast, will obtain bigger ecological benefits, economic benefit and social benefit.
Description
Technical field
The present invention relates to the modification method of a kind of gangue, belong to the processing technology field of gangue.
Background technology
Gangue is the product of coal mining and washing process, has nutrient-deficient, content of beary metal high, mostly
Number plant is difficult to survive above.In addition, coal gangue hill can move in surrounding enviroment by the form such as leaching, air slaking,
Soil, water body, plant are enriched with, environment and human body are caused serious harm.By the improvement to gangue, can be to it
It is fixed thus prevents landslide, the content of minimizing heavy metal, reach to improve the physicochemical property of coal gangue hill, the mesh of Environment control
's.
Caulis Miscanthis floriduli (Vetiveria zizanioides L.) has another name called Vetiveria zizanoides, is grass family herbaceos perennial, tool
Having adaptable, growth and breeding is fast, well developed root system, the drought-enduring resistance to characteristic such as lean, has that " draft in the world with the longest root system is planted
Thing " title.It can be at metal tailings ground normal growths such as the zinc that not even a blade of grass grows, habitat is the most severe, lead.The present invention is mainly led to
Cross the way at gangue plantation Caulis Miscanthis floriduli, select when gangue is improved, the Caulis Miscanthis floriduli optimum plantation time.
Summary of the invention
The technical problem to be solved in the present invention is: provide the modification method of a kind of gangue, green by plant Caulis Miscanthis floriduli
Change improvement, it is possible to be substantially improved leaching and the air slaking of gangue, reduce environment and the harm of human body, and its economic worth is high,
To solve problems of the prior art.
The technical scheme that the present invention takes is: the modification method of a kind of gangue, and the method comprises the following steps:
(1) breeding: by Caulis Miscanthis floriduli seed in cultivating soil, seedling raise period selected in April, after two months, by grow
Caulis Miscanthis floriduli nursery extracts with root, and the soil around subsidiary root system, keeps the root containing soil to become gyroscope-like structure；
(2) gangue arranges: gangue piling mountain, and is organized into the inclination angle gently sloping surface less than 30 °, gently sloping surface is terrace-type,
It is arranged to horizontal banded structure plantation plane；
(3) plantation hole is set: arranging multiple plantation hole in plantation plane, plantation hole spacing in the rows is 90cm, and plantation hole is arranged in a crossed manner；
(4) plantation: in step (1) band soil Caulis Miscanthis floriduli nursery utilize foliage-spray method to use root-inducing powder after, be planted in
In coal gangue hill, the degree of depth of plantation all covers with root system and is advisable, and is then showing earthing, manual compaction；
(5) Caulis Miscanthis floriduli is after coal gangue hill field planting, and the initial stage regards the climate condition that sample ground is concrete, gives process of periodically watering.
(6) until Caulis Miscanthis floriduli grow to 30-50cm long time, be no longer managed, long-time routine observation.
Beneficial effects of the present invention: compared with prior art, the effect of the present invention is as follows:
(1) present invention uses Caulis Miscanthis floriduli to carry out the improvement of gangue, because Caulis Miscanthis floriduli adapts to various soil environment, as strong acid is strong
Alkali, heavy metal and arid, accumulated water, the condition such as barren, its well developed root system, depth prosperity root system can be as deep as 2 ~ 3m, and root diameter is general
It is 0.7 ~ 0.8mm, thus content of beary metal in the landslide of coal gangue hill can being prevented and reducing it, it is substantially improved the ring of coal gangue hill
Environment pollution, reduces the injury to human body；
(2) owing to Caulis Miscanthis floriduli is mainly by tillering propagation, it is also possible to sexual propagation, growth is fast, and resistance has and well penetrates
Property, the excellent mechanical property such as tensile strength, can in the area growth that temperature be-10 ~ 50 DEG C and annual rainfall 300 ~ 6000mm, because of
And the technological investment of Caulis Miscanthis floriduli is few, the cycle is short, produce effects fast, bigger ecological benefits, economic benefit and social benefit will be obtained；
(3) Caulis Miscanthis floriduli is 600g/m to the interception of earth's surface soil losses2, and timothy is only 89g/m2, thus for keeping water
Soil has more preferable effect；
(4) Caulis Miscanthis floriduli or best in quality, the green crop of stable high yield, high-quality hand weaving material and commercial paper, perfume (or spice)
The raw material of essence, thus its economic worth is high, gain quick return, substantially increases the economic benefit of coal gangue hill；
(5) fragrance ingredient of Caulis Miscanthis floriduli can greatly reduce the production cost of Caulis Miscanthis floriduli, also with preventing and treating moth and production perfume
Bring economic benefit widely；
(6) the low compensation of Vetiveria (C4) plant, photosynthesis is strong, and with regard to germination and growth during Wen Da 10 DEG C, plantation is easily.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described further.
Embodiment: the modification method of a kind of gangue, the method comprises the following steps:
(1) breeding: by Caulis Miscanthis floriduli seed in cultivating soil, seedling raise period selected in April, after two months, germination is long
The Caulis Miscanthis floriduli nursery gone out extracts with root, and the soil around subsidiary root system, keeps the root containing soil to become gyroscope-like structure, it is possible to allow
Seedling rapidly adapts to environment within the growth transition period, improves adaptive capacity to environment；
(2) coal gangue hill arranges: gangue piling mountain, and is organized into the inclination angle gently sloping surface less than 30 °, gently sloping surface is terraced fields
Formula, is arranged to horizontal banded structure plantation plane, and the slope structure of ladder facilitates management and the harvesting of Caulis Miscanthis floriduli, the most beneficially cus-cus
Grass carries out photosynthesis, improves the quality of Caulis Miscanthis floriduli；
(3) plantation hole is set: arranging multiple plantation hole in plantation plane, plantation hole spacing in the rows is 90cm, and plantation hole is arranged in a crossed manner, profit
Intersect in the root system carrying out Caulis Miscanthis floriduli, be more conducive to conserve water and soil, prevent landslide；
(4) plantation: in step (1) band soil Caulis Miscanthis floriduli nursery utilize foliage-spray method to use root-inducing powder after, be planted in
In coal gangue hill, the degree of depth of plantation all covers with root system and is advisable, and is then showing earthing, manual compaction；
(5) Caulis Miscanthis floriduli is after coal gangue hill field planting, and the initial stage regards the climate condition that sample ground is concrete, gives process of periodically watering, passes through
Water and above-mentioned spray root-inducing powder is so that Caulis Miscanthis floriduli is quickly taken root at coal gangue hill；
(6) until Caulis Miscanthis floriduli grow to 30-50cm long time, be no longer managed, long-time routine observation.
The above, the only detailed description of the invention of the present invention, but protection scope of the present invention is not limited thereto, and any
Those familiar with the art, in the technical scope that the invention discloses, can readily occur in change or replace, should contain
