In some embodiments, in the step B, the line-spacing of the strain of the gold leaf sedum lineare is 25cm × 25cm, institute
Stating indigenous plant is acidproof indigenous plant.
It is planted the beneficial effects of the present invention are: being prepared by using gangue disintegrating slag, flyash, waste edible fungus bacteria residue and loam
Layer matrix is trained, coal gangue hill is covered with cultivating layer matrix.Good growing environment can be provided to the rehabilitation plant of plantation,
It is capable of forming good vegetation cover, effectively controls the release of coal gangue pollution substance.Meanwhile cultivating layer matrix production cost
Low, good economy performance.
Specific embodiment
The present invention provides a kind of efficient ecological restoration method for coal gangue dump, include the following steps:
A, prepare cultivation layer matrix, using based on parts by volume 10~20 parts of 20~30 parts of gangue disintegrating slag, flyash, in
Layer matrix is cultivated in 5 parts of 10~20 parts of the herbal medicine dregs of a decoction, 10~20 parts of waste edible fungus bacteria residue and loam preparations；
B, coal gangue hill is organized into less than 30 ° of inclination angle gentle slope, digs a depth 60cm, straight every 3~5m according to landform
Diameter is that the round of 60cm kind plants hole, and by culture layer matrix laying to coal gangue hill surface layer, 4~6cm of thickness, plantation hole is filled up；
C, upper in cultivation layer matrix to plant gold leaf sedum lineare, the line-spacing of the strain of gold leaf sedum lineare is 25cm × 25cm, and
Large-scale acidproof indigenous plant seedling is planted in plantation hole；
D, after gold leaf sedum lineare covers massif surface substantially, bracken spore is taken to be broadcasted sowing；In fiddlehead and indigenous plant
After growth survival is grown up, the reparation of coal gangue hill ecology is completed.
Invention is described in further detail with specific embodiment below.
Embodiment 1
The present embodiment is outdoor simulating pot experiment, and steps are as follows:
1, the newly generated sulfur-bearing gangue sample of collection of coal mine paneling, air-dries indoors, is crushed, it is broken to sift out 3mm or less
Slag stores for future use.
2,25 parts of part gangue disintegrating slag, 15 parts of flyash, 15 parts of Chinese herbal medicine dregs, waste edible fungus bacteria residue 15 by volume
Part, 5 parts of loam preparation coal gangue storage yard cultivation layer matrix.
3, using the polyethylene Dual-color plastic feed basin of 150 (bore 15cm, high 13cm), basin is built-in to fill and present the gangue sample got ready
Product, surface cover the culture layer matrix of 5cm, not cover matrix and cover loam as control.5 plants of gold leaf sedum lineares are uniform
It plants in flowerpot, drip tray is arranged in bottom.
4, by 1 times a week, pouring 500mL collects rainwater routine servicing every time.Sampling is primary weekly, measurement percolate pH,
EC value, Eh, Fe, Mn, heavy metal and SO42- content.Test result shows that the growth of gold leaf sedum lineare is prosperous in cultivation layer matrix
It contains, loam adjoining tree slow growth, and the growth of pure coal gangue adjoining tree stops, plant more than half are dead.Cultivate half a year
The gangue of post-processing.
5, after cultivating 3 months, gold leaf sedum lineare has covered whole basin, and bracken spore is broadcasted sowing stromal surface, is normally managed and protected,
Spore germination can be observed after 2 weeks, fiddlehead plant is grown after 2 months.
6, percolate is detected in whole process and is found, the potting later period, its pH value was in neutrality, and various content of beary metal subtract
Few 20% ± 5%.
