Description
Technical field
The cogongrass growth-promoting media and preparation method thereof that the present invention relates to a kind of applied to mining soil reparation, belongs to environmental protection technology
Field.
Background technique
Cogongrass (scientific name: Imperata cylindrica (L.) Beauv.) is grass family, the plant of cogon perennial herb
Object, stalk is upright, 80 centimetres of Gao Keda, saves hairless.Leaf sheath is gathered in stalk base, and tip of a leaf film quality, stalk leave piece is narrow linear, usually interior
Volume, tapering top is in thorn-like, and lower part is tapered, and matter is hard, mask pubescence on base portion.Panicle is dense, and the first lemma ovate drapes over one's shoulders needle
Shape, the second lemma and its glumelle are closely equal, oval, and top has fissure and cilium；Style is elongated, atropurpureus, caryopsis ellipse,
The flowering fruit bearing stage 4-6 month.
Cogongrass has a powerful root system, root system can secured soil, there is good protective effect to soil, China is from changing
Since leather is open, country greatly develops industry, since mineral resources are excessively developed, causes many mining soils by more serious broken
Bad, especially outdoor mining mineral resource directly polluted the ecosystem environment on mine periphery, make soil, vegetation and water source all
It is seriously damaged.Without the protection of vegetation, the easily natural calamities such as formation mud-rock flow, great danger is brought to locality construction
Evil.
Have growth fast in view of cogongrass, takes root depth, it is very big to the protective effect of soil, and local preparation can be changed
Environment promotes other plant to grow, and forms good ecological environment, since the soil in current most domestic mining area is by more
Serious pollution, especially metal ion are excessively exceeded, cause preparation to destroy serious, and the present invention is based on the above problem, exploitations one
Kind growth-promoting media can promote cogongrass in mining area grown, improve environment of mining area, rehabilitating soil.
Summary of the invention
To solve the above-mentioned problems of the prior art, a kind of cogongrass growth-promoting media is provided, cogongrass can be promoted contaminated
Mining area growth, improve the vegetation environmental in mining area, good repair played to soil.
In order to realize that foregoing invention, embodiment are as follows:
A kind of cogongrass growth-promoting media applied to mining soil reparation, is made of the following components:
Preferably, plant corruption liquid and preparation method thereof is as follows:
1, plant leaves or tree stem are taken, is dried to that moisture content is 20-40%, crushed 10 meshes, be added to enzymatic hydrolysis
In tank, the 2-4 times of water measured of plant weight after being equivalent to crushing is added, stirring is heated to 50-70 DEG C.
Preferably, the leaves of plants or tree stem are one of tangerine tree, camphor tree, pine tree, nectarine tree or several
Combined leaf or tree stem.
2, alkali regulator is added, adjusting pH value is 7-9, and 0.5-1.5% times that plant weight after being equivalent to crushing is added is measured
Cellulose complex enzyme, digest 3-6 hour, be heated to 90-100 DEG C, keep 10-15min, 200 meshes of mistake are concentrated into relatively close
Degree is 1.2-1.8 (55-60 DEG C of detection).
Preferably, the alkali regulator is one of sodium hydroxide, sodium carbonate, sodium bicarbonate or several.
3, by above-mentioned concentrate closed preservation 30-40 days, controlling environment temperature is 10-20 DEG C, and rhizoma imperatae juice, stirring is added
After mixing, continue to place 60-90 days.
Preferably, the rhizoma imperatae juice additional amount is 0.2-0.5 times of concentrate weight and measures that preparation method is as follows:
1, it takes rhizoma imperatae appropriate, smashes it through 200 meshes.
2, the water for being equivalent to 2 times of rhizoma imperatae weight amounts is added, stirring is heated to reflux 2-3 hours, is filtered, and filtrate is concentrated into
Relative density (55-60 DEG C of detection) between 1.05-1.1.
Preferably, the cogongrass growth-promoting media, constituent are as follows:
Preferably, the cogongrass growth-promoting media the preparation method is as follows:
1, suitable quantity of water is taken, is heated to 60-70 DEG C, is added hydroxyethyl cellulose and triethyl citrate, suction is-
0.6 to -0.8Mpa, it is kept for 2-4 hours.
2, propylene glycol, ammonium carbonate, potassium sulfate is added and continues stirring 2-4 hours, plant is added and degenerates liquid, stirs 1-3 hours
Afterwards.
It is characteristic of the invention that obtain a kind of suitable cogongrass root growth, and can using enzymatic hydrolysis and the means of fermentation again
The plant of cogongrass root system is enough stimulated to degenerate liquid, due at certain acidity, stimulating rhizoma imperatae to adapt to acidic environment after fermentation, promoting
The acidic environment in cogongrass adaptation mining area.The present invention is additionally added hydroxyethyl cellulose, and viscosity is strong, soluble easily in water, lemon triethylenetetraminehexaacetic acid
Ester then has very strong thickener, increases the viscosity of hydroxyethyl cellulose, can form layer protecting film in cogongrass root system outer layer,
Since hydroxyethyl cellulose and triethyl citrate belong to nonionisable substance, the film of formation has certain repulsion to ion
Property, destruction of the metal ion to rhizoma imperatae system is prevented, therefore the versus environmental for being able to maintain root system is stablized, while its hydrophily, energy
Enough guarantee that hydrone passes through, does not influence the growth of root system.
Beneficial effects of the present invention also reside in:
1. the present invention obtains a kind of growth-promoting media of promotion cogongrass growth, especially cogongrass can be promoted in contaminated mining area
Growth.
2. growth liquid preparing process of the invention is simple, easy industrialization and scale, particularly suitable for large-scale production and
Management.
