Description
Technical field
The present invention relates to a kind of desertification geobiont improved materials and application process.
Background technology
Statement in this part merely provides the background information relevant with present disclosure, thereby increases and it is possible to does not form
Prior art.
Desertification has become the problem of globalization, and desertification refers to due to artificial and natural cause comprehensive work
With so that the degeneration of arid, semiarid or even Semi-humid area natural environment (including salination, deterioration of grasslands, soil erosion, soil
The tool using a certain environmental factor as mark such as earth desertification, narrow sense desertification, vegetation desertification, period of history sand dune reach invasion
The natural environment of body is degenerated) total process.
By further studying it can be found that being used as the sand grains of inanimate matter mineral, its surface charge is enlivened.It is more dry pure
Net sand, the repulsive force between sand grains are bigger.This just makes its own possess the condition quivered.Therefore when being acted on by wind-force,
It can be easy move.
At present, conventional improvement system of fixing the sand mainly has following three kinds：
1st, mechanical sand fixation is formed in a manner of the setting of the material such as batten, soil block, stone and stalk and its product or tiling etc.
Sand-protecting barrier, this method can only hinder Sand Movement, can not be effectively improved sand body physicochemical property, can not meet to desertification ecological afforestation
Needs；
2nd, chemical sand-fixing, using chemical material and technique, building one layer to prone soil top layer can prevent wind-force from blowing to raise
There is the bonding course for keeping moisture and improveing sand ground property again, this method can not equally be effectively improved desertification soil physical chemistry
It matter, can not persistently meet demand of plant growth, and be also easy to produce secondary pollution；
3rd, biological breadcrust, it is by its mycelia such as bacterium, fungi, algae, lichens, liver moss, secretion etc. and soil gravel
The compound formed is bonded, is the important ground mulching type in arid and semi-arid area, biological breadcrust, which has, promotes soil development
Characteristic, but the process and its slowly, the foundation of the Tiny ecosystem circle of high-biomass can not be met in the short time.
China's desertification land is expanded with annual 2460 square kilometres of speed.And change arid, semiarid zone desert
The fundamental solution of changeization tendency is rapid large-area increase Soil reference materials, generation soil granular structure, builds plant
By the formation condition with edaphon, limited precipitation is set sufficiently to become oasis.
Therefore prior art is urgently improved and developed.
The content of the invention
The technical problem to be solved in the present invention is to provide one kind persistently to strengthen soil fertility, builds the soil of suitable for plant growth
Earth environment desertification geobiont improved materials and application process.
The present invention technical solution be：
A kind of desertification geobiont improved materials, material is inhabited by microorganism and functional microorganism flora forms；This is micro-
Biology inhabites material and provides nutriment for that can be grown for functional microorganism.Microorganism inhabites material as that can be the micro- life of function
Thing growth provides materials such as (polysaccharide, starch, the celluloses) of nutriment；
The functional microorganism includes nitrogen-fixing bacteria, production slime mould, more mycelia fungies, photosynthetic bacteria.Functional microorganism mycelia twines
Around sand grains, sand grains is wrapped up, and bonded sand grains by the polymer of secretion, makes husky body stable, there is very strong sand-fixing effect.
Activity of the functional microorganism in material is inhabited, increase material surface hydrophilic radical, porosity increase so that microorganism-material
Material mixture has very strong water absorbing capacity；Desertification geobiont improved materials catabolite can be absorbed by root system of plant,
It is continuously plant and nutrient, the material circulation of structure desert soil is provided.
Component ratio is pressed in improved materials：Microorganism inhabites 10~20 parts of material, 0.1~1 part of microorganism species.
A kind of application process of desertification geobiont improved materials, comprises the following steps：S1, above-mentioned improved materials are equal
Even sheds on prone soil surface；S2, improved materials are mixed with prone soil.
Dosage of the improved materials in desertification soil be 5%~7%, with desertification soil interacting depth be 10cm~
20cm。
Beneficial effects of the present invention：
The prone soil that the present invention is applied to Desertification carries out biological modification；By building microorganism to sand
Flora, and the material of inhabiting for being available for microorganism growth to need is provided, functional microorganism growth can produce a large amount of mycelia and secrete more
The polymer of sugar, sand grains is wound and wrapped up by substantial amounts of mycelia, and is bonded sand grains by the polymer of secretion, makes Sha Tiwen
It is fixed, play very strong sand fixation.Reservoir bed is built for desertification soil simultaneously, accelerates soil material circulation, lasting enhancing soil
Earth fertility, build the soil environment of suitable for plant growth.Engineering construction is using organic fertilizer scattering machine, rotary cultivator, sprinkling truck by material
Material is applied to desertification soil improvement.Engineering construction is convenient, suitable for being widely applied.
Embodiment
Embodiment：
Experiment place is Beijing, is tested the date No. 6.1-7.30, naked thing above trial zone.
Test block is 10*30 (300 ㎡) block, and drift-sand thickness of soil is more than 50cm.By 20cm thickness drift-sand soil
5% addition desertification geobiont improved materials of weight, material are uniformly overlying on sandy soil surface, using rotary cultivator by material
It is well mixed with sandy soil, interacting depth 20cm.Seed is sprinkled in soil surface, is slightly mixed seed with surface soil using rake
Close.Sprinkled water using sprinkling truck to trial zone.
Periodic maintenance, a water is poured within every 3 days, until germination.
Stop watering, percentage of seedgermination 32% within 15th day.Hereafter no longer water to trial zone, tieed up completely with local rainfall
Hold plant growth.
