The method for reconstructing of the Black Soil Sloping vegetation of the embodiment of the present invention is specifically described below.
The method for reconstructing of Black Soil Sloping vegetation provided by the invention, based on manual reversion and revegetation, with Forbidden grazing
Supplemented by, using certain agronomic measures by suitable Local grass-seed, the shape after Alpine meadow of the gradient more than 25 ° is seriously degenerated
Into secondary barren on establish artificial vegetation, recover vegetation and stable soil top layer to reach, promote litter layer long term accumulation to turn
Change increase soil nutrient, the purpose to prevent erosion.
Specifically, comprise the following steps：
S1, kill mouse；
The secondary barren that Black Soil Sloping is formed after seriously being degenerated for Alpine meadow of the gradient more than 25 degree, more than soil layer 5cm,
Secondary barren also has some planting conditions, but soil fertility significantly declines, it is impossible to what plantation required to soil
Crops.Simultaneously as vegetation is few on Black Soil Sloping, and the ground such as Qinghai is dried, and other diseases are not likely to produce in growing process
Insect pest, thus, it is only required to go out except the mouse trouble in soil or periphery, it can then ensure the growth of the vegetation of later stage plantation, and nothing
Other prevention and control of plant diseases, pest control need to be carried out again.
The method specifically to kill mouse can be that creotoxin aqua mixes the biological control methods such as bait and/or granule to Black Soil Sloping
Killed mouse, prevent and treat the mouse during vegetation is planted and erosion is stung to the root of grass seeds or leaf, ensure the grass seeds of plantation
Normal growth.And it is to carry out in the winter time to kill mouse, muroid can be prevented in destruction of the spring to remnants some vegetation.
S2, pre-treatment；
Black Soil Sloping is ploughed shallowly before plantation, gently harrows and applies fertilizer.Due to severe water and soil erosion on Black Soil Sloping, soil layer is thin,
Therefore agricultural machinery can not operate, and carry out farming by manpower or small cultivator substantially.Therefore, in order to mitigate the work of personnel
Dynamics, meanwhile, prevent the moisture in soil layer etc. to be further lost in, only ploughed shallowly before planting, then increase porosity, remove
Weeds, while also have water retention.
Site preparation is carried out to Black Soil Sloping according to the demand of sowing after shallow plowing.If needing to carry out bar sowing, then need to black earth
Slope sets ridge as railway carriage or compartment, if needing to carry out broadcasting sowing kind, then need not carry out setting ridge as railway carriage or compartment.
Light rake can be cut large volume of soil piece to obtain the smaller soil piece of volume so that soil
Water-saving effect is lifted so that the moisture content of soil adds 1-2 times than the soil do not harrowed gently, is provided favorably for the growth of grass seeds
Condition.It is then more favourable native beneficial to the breeding of the microorganism in soil meanwhile the temperature of soil raises 1.5-2.5 DEG C after light rake
The growth of organic substance in earth, abundant nutriment is provided for the growth of grass seeds, accelerates the reconstruction of vegetation.
Then applied fertilizer, fertilising is that per hectare applies Diammonium phosphate (DAP) 225-300kg, or per hectare applies sheep manure
When 900-1200kg, or the application that can be combined with the ammonium of sulfuric acid two and sheep manure, the ammonium of sulfuric acid two and sheep manure combine application, often
Hectare applies 100-200kg Diammonium phosphate (DAP) and 400-800kg sheep manures.Diammonium phosphate (DAP) is while nitrogenous and phosphorous composite fertilizer,
Nitrogen phosphorus can be provided for soil simultaneously, and its concentration is high, and good fertility can be quickly provided for soil.Sheep manure is by corruption
The pure sheep manure of ripe fermentation, it is far above the excrement of other domestic animals using the fertilizer efficiency of sheep manure, it can effectively improve soil, loose
Soil, the soil erosion of soil and hardened is prevented, the water holding capacity of soil is also lifted, stimulates the growth of the root system of grass seeds plant
Development, then accelerate the reconstruction of Black Soil Sloping vegetation.
S3, seed selection；
Because the soil fertility of Black Soil Sloping is poor, therefore the grass seeds planted should require relatively low to fertility, and grass seeds is easily raw
It is long.And because the present invention is to rebuild the vegetation of Black Soil Sloping, then fertility of soil of recovery Black Soil Sloping etc., therefore, is being planted
It should be interplanted during grass planting kind, avoid the vegetation for the reconstruction Black Soil Sloping that single grass seeds can not be well, while according to the life of herbage
State biological characteristics and selection grass seeds be rhizome type grass seeds and it is resistance to herd type grass seeds, above two grass seeds be locality introduce a fine variety it is tame and docile
The Local grass-seed of change, wide adaptability and strong stress resistance, easily form the strong perennial grass seeds of turf, water and soil conservation ability and its group
Close, artificial vegetation's stability of planting is good, and ecological benefits are notable.And rhizome type grass seeds and resistance to type grass seeds of herding can quickly form grass
Skin, reduce soil erosion.
Further, rhizome type grass seeds includes Qinghai Grassland annual bluegrass, and resistance to type grass seeds of herding includes Mai Bincao.Qinghai Grassland is early
Ripe standing grain is that the wild species that Livestock Research and Veterinary Academy of Qinghai Prov. grows from height above sea level 4000m Dari County form through cultivation domestication for many years
One cultivar, there is the good characteristics such as resistance is extremely strong, leaf amount is abundant, palatability is good, rhizome is flourishing, resistance to herding property is strong, its
Turf can be quickly formed on Black Soil Sloping, then recovers vegetation and stable soil top layer.Mai Bincao has in growth period blade to be pierced
Hair and big hair, stalk fiber is flourishing, is not easy by feed intake, is the ecological grass seeds of extremely frigid zones revegetation.And pass through domestication

It can be acted on well with Black Soil Sloping, then accelerate the formation of turf, reduce soil erosion.
S5, post processing；
Earthing is carried out after the completion of plantation, it is poor to the stability force of grass seeds because the fertility of Black Soil Sloping is poor, if without earthing,
Grass seeds is easily taken away by wind or rainwater, and then influences the formation of turf, influences the recovery of vegetation, and one is covered on grass seeds
Layer soil, can prevent grass seeds to be blown away or washed away by rainwater.Meanwhile one layer of soil of covering can also effectively water conservation,
And grass seeds various pieces can obtain good insulation, promote absorption of the grass seeds to each nutriment.
Further, the thickness of earthing is 1-2 centimetres, and the thickness of earthing is not easy blocked up, prevents that the young shoot of grass seeds can not
Soil is drilled out, then ensures the normal growth of grass seeds.Meanwhile prevent earthing blocked up and cause in soil temperature too high and caused by
Situations such as grass seeds ablation or corrosion.
Planting site, which is suppressed, after the completion of earthing to be covered in the soil compression on grass seeds surface so that grass seeds and soil knot
Conjunction is closer, and has good Water-saving effect, meanwhile, prevent wind, rainwater etc. from changing the position of grass seeds, then ensure Black Soil Sloping grass
The formation of skin, increase the stability of artificial vegetation, reduce soil erosion.
Because Black Soil Sloping soil fertility difference can not use plant equipment to carry out farming, therefore, above-mentioned earthing, suppression are also
Artificial construction.
Can have at the initial stage of vegetation growth in plantation ground surface covering layer of non-woven fabric, covering non-woven fabrics after the completion of suppression
Effect suppresses soil erosion, at the same can heat-preservation ventilating, accelerate the growth and breeding of grass seeds, improve the survival rate of grass seeds, and to stable
Upper soll layer has good effect, and after the completion of vegetation growth, non-woven fabrics and can enough promotes the long-term accumulated of litter layer, then carries
Rise the nutrient of soil.And the non-woven fabrics covered in the later stage without shutting down, and long-term existence is in Black Soil Sloping, therefore, covering
Non-woven fabrics is the non-woven fabrics that can be degraded, and the thickness of non-woven fabrics is 16-18g/m2, the non-woven fabrics of the ranges of thicknesses is in soil
It can well be degraded with the decomposition of withered grass, will not will not then cause environmental pollution always present in soil.
Said process has completed artificial vegetation, but only artificial vegetation is inadequate, it is necessary to give Black Soil Sloping one
The time of Duan Huifu life, and the closure against grazing within this time, herded specifically prohibiting to Black Soil Sloping fence, fence taboo is herded can
Ensure the growth of vegetation, promote the formation of turf, beneficial to stable soil top layer, and contribute to the formation of litter layer.
