S101, bastard coal clitter domatic on lay three-dimension vegetative net.
The bossed net bag of three-dimension vegetative net band, when laying, lays with the direction that net covering is outside.Will have lap between adjacent three-dimensional vegetation net, lap about 20 centimetres, object is to leave space between adjacent three-dimensional vegetation net.After completing, in order to prevent three-dimension vegetative net to be shifted, U-shaped nail need be adopted to fix, nail is about 50 centimetres, fixes a U-shaped nail every 1 meter.But not as limit, bamboo let also can be adopted to fix, but adopt bamboo let to fix, in order to fixed, the top of bamboo let is thicker than bamboo let other parts.
S102, in the net bag of above-mentioned three-dimension vegetative net, fill coal gangue particle.
Usually, the coal gangue particle diameter of filling is less than 0.8 centimetre, and such particle can enter net bag smoothly.In concrete filling process, be by a large amount of coal gangue particle spreadings on three-dimension vegetative net, coal gangue particle oneself enters net bag, until all net bags are filled, and on three-dimension vegetative net, forms the coal gangue particle layer of 1 to 2 centimetre.
S103, sow mixed plant seed filling on the three-dimension vegetative net after above-mentioned coal gangue particle.After sowing, seed can remain in the gap between coal gangue particle by nature, then grows.Finally on bastard coal clitter, form vegetation.
In addition, three-dimension vegetative net has following feature: the net bag 1) on three-dimension vegetative net, has good fixation for spreading at the coal gangue particle netted in bag and seed.2) due to the existence that above-mentioned net wraps, slow down the impact strength of raindrop; Further, due to being uneven of net covering, make wind, current etc. produce countless little whirlpool at net surface, slow down wind erosion and the erosion that causes of current.3) graticule between the basal layer of three-dimension vegetative net and net covering grid is staggered, not only there is good fixation to the coal gangue particle in net bag and seed, and along with the growth of root system of plant, coal gangue particle during three-dimension vegetative net can wrap with net and root system of plant are wound around mutually, form fine and close cover layer, increase the erosion resistance on domatic top layer further.4) three-dimension vegetative net has good heat insulation effect, is conducive to the germinating growth of vegetation.
In the present embodiment, bastard coal clitter domatic on lay three-dimension vegetative net, then in the net bag of three-dimension vegetative net, fill coal gangue particle, and the three-dimensional after coal gangue particle is on duty sows mixed plant seed on the net, to form vegetation on bastard coal clitter filling.So just directly can utilize existing bastard coal clitter, without the need to being transported by bastard coal clitter, greatly reduce the processing cost of gangue, and form vegetation on bastard coal clitter, significantly reduce the environmental pollution of gangue.
It should be noted that, above-mentioned mixed plant seed can comprise any combination of following seed: Bermuda grass (Cynodondactylon) seed, white sweet clover (Melilotusalbus) seed, shrubby flase indigo (Amorphafruticosa) seed, summer cypress (Kochiascoparia) seed, shrub lespedeza (Lespedezabicolor) seed, horse sour jujube (Indigoferapseudotinctoria) seed.
Particularly, the bastard coal clitter formed owing to mining is domatic, and poor stability, variations in temperature are violent, arid, malnutritive, and most plant is difficult to survive, and these seeds above-mentioned are all through great many of experiments and determine, the plant that survival rate is very high on gangue.Sow and preferably to carry out in season with heavy rainfall, the uniformity sowed when sowing, should be ensured.The mixed proportion of concrete seeding quantity and above-mentioned different plant seed can be determined according to restoration of the ecosystem object, construction seasons.
