Description
Technical field
The present invention relates to bank protecting methods, and in particular to a kind of soil improvement fiber is sowed grass seeds by duster matrix and its in slope ecological recovery
Application in the process, belongs to environmental protection technical field.
Background technique
Soil improvement is sowed grass seeds by duster matrix, is to sow grass seeds by duster during side slope protection to the soil improvement material on side slope surface.For inclined
Far, edaphic condition and side slop's conditions it is poor side slope improvement, especially repair the roads and take the Soil Slope content of the side slopes such as Tu Chang few, native
Matter is poor, and surface is not easy to adhere to, and therefore, traditional soil improvement material is difficult to effectively improve the side slope seriously degenerated.
The protection of side slope is to permanently effective, it is necessary to guarantee vegetation growth steady in a long-term in side slope.Existing method
The soil improvement layer of middle covering, is only to provide the nutrient of plant growth, and plant can be very good to grow in this layer of soil of covering.
But root system of plant is difficult to extend in side slope original soil, this is also the basic of vegetation degeneration after bank protecting method several years of the prior art
Reason.Only side slope original soil is improved, just plant can be made to grow in side slope for a long time.
A kind of soil conditioner of CN201710321589.9 and its preparation method and application, the soil improvement of the disclosure of the invention
Agent includes following components by weight: wood-fibred, charcoal, humus, polysaccharide, algae essence, Trichoderma, nitrogen-fixing bacteria, mushroom
Mushroom slag, carboxymethyl chitosan, biochemical fulvic acid sodium, diatomite, conch meal and composite bacillus.Wood-fibred disclosed by the invention
By centainly heating, but a kind of charcoal is substantially still fallen within, and not formed can be adapted for serious side slope of degenerating
The fibre structure of soil property.The invention also discloses the preparation method of the soil conditioner, application and application method, the soil
Modifying agent has good improvement soil physico-chemical property and promotes the performance of plant Cheng Ping, and preparation and method of administration are simple, benefit
In popularization and application.Though the invention can improve side slope soil, but still be the scheme of traditional increase side slope nutrition, this for
Commonly the more slow side slope of the gradient is applicable, and for slag stockyard, rubble stockyard, repairing the roads takes the serious side slope of the degeneration such as Tu Chang,
Just it is unable to reach the effect；Serious side slope water holding capacity of especially degenerating is bad, although increasing many nutritional ingredients,
But it outflows with water the habitat after can not seriously keeping improvement for a long time to stablize.
The side slope improvement poor for remote, edaphic condition and side slop's conditions, especially repairs the roads and takes changing for the side slopes such as Tu Chang
Good, had the following problems using the solution of the prior art: hypothallus of sowing grass seeds by duster can not combine together with side slope original soil, not have
Thoroughly change the character of side slope original soil (raw-soil), water conservation, fertilizer-preserving ability are poor.Root system of plant only can be raw in improvement soil horizon
It is long, it can not also be deep into the original soil of side slope, form two layers of skin phenomenon, vegetation degeneration causes slope protection and revegetation structure whole
Body function failure, can not carry out side slope protection for a long time.
Summary of the invention
Against the above technical problems, the present invention provides a kind of soil improvement fiber and sows grass seeds by duster matrix and its in slope ecological recovery
Application in the process will reach following goal of the invention: side slope that can be poor suitable for remote, edaphic condition and side slop's conditions is anti-
Shield, the hypothallus that makes to sow grass seeds by duster combine together with side slope original soil, effectively improve the soil property of side slope original soil, improve soil water-retaining guarantor
Fertile ability.Root system of plant, which is deep into the original soil of side slope, to be grown, and is avoided the formation of two layers of skin phenomenon, is prevented vegetation degeneration.
To reach the purpose, the technical scheme is that
A kind of soil improvement fiber is sowed grass seeds by duster matrix, and the matrix of sowing grass seeds by duster includes heat treatment wood-fibred, the heat treatment wood-fibred
Mass percentage be 79-90%.
The heat treatment wood-fibred: for porous staple fiber, diameter 0.1-1 ㎜；Length is fiber content >=50% of 2 ㎝.

The marine algae extract includes fucoidin, algal polysaccharides, mass ratio 3:1-2.
The matrix of sowing grass seeds by duster, in parts by weight, including heat treatment wood-fibred 85-90 parts, 2-3.8 parts of marine algae extract,
2-3.5 parts of composite bacteria agent, 5-7 parts of humic acid, 0-6 parts of bamboo charcoal, 0-4 parts of chitin, 1.5 parts of asparatate 0-.
A kind of soil improvement fiber is sowed grass seeds by duster application of the matrix in slope ecological recovery, and soil improvement fiber is sowed grass seeds by duster matrix use
Amount is 280-510g/ ㎡.
The application, soil improvement fiber are sowed grass seeds by duster the sowing grass seeds by duster with a thickness of 3-5mm of matrix.
After soil improvement, the soil organic matter content > 10% of side slope original soil, porosity be 59 ± 2%, water content 15% with
On, biologically effective N content > 150mg/kg, biologically effective P content > 70mg/kg, biologically effective K content > 110mg/kg.
Compared with prior art, technical solution of the present invention has the advantages that
(1) soil property of remote, edaphic condition and the poor side slope original soil of side slop's conditions is thoroughly improved using the method for the present invention,
Hypothallus of sowing grass seeds by duster can assimilate with side slope original soil to be structure as a whole, and improves soil nutrient, retain water and nutrients ability is strong, does not move back after improvement
Change.After soil improvement, the soil organic matter content > 10% of side slope original soil, porosity 59% or so, 15% or more water content, biology
Effective N content > 150mg/kg, biologically effective P content > 70mg/kg, biologically effective K content > 110mg/kg, soil texture are steady
It is fixed.
(2) the method for the present invention is used, coverage reaches 70% after sowing vegetable seeds 28 days, and ground biomass reaches
0.65g/cm2.After being carried out revegetation 3 years using the present invention to raw-soil side slope, vegetation coverage is 97% or more, geodyte
Amount reaches 9.8g/cm2.Using the method for the present invention, the hypothallus sowed grass seeds by duster assimilates integral mellow soil structure, plant with side slope original soil
Root system is able to fast-growth, and root system of plant can be made to be deep into the original soil of side slope and grown.By being seeped into side slope original under matrix of sowing grass seeds by duster
In soil and root system of plant is deep into side slope original soil and realizes fixation, to realize that infiltration type is improved, fundamentally avoids and changes
The separation problem of " two layers of skin " occurs for good soil and side slope original soil.Plant long term growth, does not degenerate.
(3) material of sowing grass seeds by duster that the method for the present invention uses can voluntarily decompose for 18 months, no pollution to the environment；At this point, plant
It can be very good to take root in side slope, grow, the long-term stabilization for keeping side slope vegetation.
