Description
Technical field
The present invention relates to a kind of ecology of ecological restoration technical field more particularly to Mountain Area of Southwest Karst Rocky Desertification on the spot
Restorative procedure.
Background technique
Karst landform refers to that solublerock is formed by variously by the corrosion of water and adjoint mechanism
Looks have karst landform ground are widely distributed Guangxi, Guizhou, Yunnan etc. of China.In recent years, with large-scale engineering construction
And mining, original geomorphological structure is changed, Rocky Desertification, severe water and soil erosion are caused, leads to karst landform shape
At bare side sloping a large amount of, that vegetation can not be restored in a short time.Water resource lacks, soil evaporativeness is big and soil depletion is noise made in coughing or vomiting
The difficult point of this special stony desertification site ecology reparation, and cause that plant emergence rate is low, the death rate is high, what restoration of the ecosystem cost increased
Main cause.Therefore how to collect to greatest extent, using sleet resource, increase the water-holding capacity for keeping soil, improve soil
Soil fertility condition is the important technical links of Karst Rocky Desertification site ecology reparation.
Summary of the invention
In view of the above-mentioned problems, the present invention provides a kind of ecological restoring method of Mountain Area of Southwest Karst Rocky Desertification on the spot, it should
The bioactive substance that ecological restoring method obtains can increase the biomass of on the spot surface algae, so that on the spot to the ring of heavy rain

Degree is 20~40 DEG C, and incubation time was 2~3 weeks, is gently mixed every 3 days 5~10 minutes, ventilation culture；Cultivate training early period
Support after, then in culture solution be added total weight 3-5% clay mineral the rudimentary plant of culture is fixed, addition
Clay mineral partial size crosses 200 meshes, then cultivates 5~7 days under static culture field.
Further, institute's clay mineral is the combination of one or more of illite, montmorillonite, vermiculite and sepiolite.
Further, the production of step (3) the packet bioactivity covering: in the liquid after step (2) culture
In, it is separately added into water-soluble cross-linked dose, accounts for the 0.5~1% of liquid total weight, adds the crosslinking agent of Ionic water-soluble,
The 0.5~1% of liquid total weight is accounted for, modified starch is added, accounts for the 1~3% of liquid total weight, by 10~15 minutes stir
It mixes, above-mentioned substance is made to the bioactivity colloidal liquid of the certain viscosity of band；Again by this bioactivity colloidal liquid by 1~
10% ratio is sprayed at the covering basic material made of the forest land dry branches and fallen leaves, bark, shredded paper of 0.5-3 centimetres of crushing
On, finally obtain the bioactivity covering that water content is 15-25%.
Further, the water-soluble cross-linker be potassium alginate, calcium alginate, alginic acid magnesium ammonium alginate one kind or
It is several.
Further, the crosslinking agent of the Ionic water-soluble is the one or more of calcium sulfate, magnesium sulfate, aluminum sulfate.
Further, the modified starch is the one or more of gelatinized starch, hinge starch and esterification starch.
Further, the application of step (4) the bioactivity covering: by bioactivity covering obtained by often putting down
The dosage of 1-5 kilograms of square rice, which is sprinkling upon, to be needed to avoid spreading heavy rain in latter 5 days on the soil of the Karst Rocky Desertification of restoration of the ecosystem on the spot
It rinses.
Compared with prior art, the present invention has the advantage that
1, the bioactive substance that ecological restoring method of the invention is prepared can increase the biomass of algae, to sudden and violent
The environmental attack of rain has good durability, the stability reunion of soil can be improved, effective travel biology soil in the short time
The effect of earth skinning, so that the bioactive substance that ecological restoring method of the present invention is prepared is covered site type group surface
When, desertification can be prevented, it can be desertification in-situ reformation at the ecological environment of suitable plant growth；
2, using ecological restoring method of the invention, rainwater can be collected to the greatest extent and reduces soil water evaporation, with
It is absorbed for plant normal growth；
3, Water holding capacity of surface and nutritional ingredient can be significantly improved, what site ecology restorative procedure proposed by the present invention obtained
Bioactivity covering is covered on original soil surface, can significantly improve water retention property, while inside bioactivity covering
The bioactive substance of addition contains nutrient water-retentions material such as nutrient solution etc., can be effectively improved the physical structure of soil, make
Soil after must improveing is rich in organic matter, and contains the necessary moisture of plant growth.
