Description
Technical field
The invention belongs to textile technology fields, and in particular to a kind of for administering the non-woven microorganism of residual mulching film harm
Soil remediation material.
Background technique
This project be can 100% natural degradation, pollution-free regenerated fiber is that non-woven base fabric made of raw material is carrier, use
Microcapsules containing extraordinary microorganism fungus kind are adhered on carrier, are implanted into the soil containing residual mulching film by degradable adhesive
In, under aerobic condition, by the decomposition of microorganism, by organic contaminants in soil, including residual mulching film exhaustive oxidation,
The inorganic matters such as carbon dioxide, water, sulfate radical, phosphate radical, nitrate anion are resolved into, achieve the purpose that soil remediation.
The research of project is that domestic and international soil remediation, pollution administration industry are put forward for the first time, creative, novelty, can
Industrialized new technology.Project is succeeded in developing, and will be solved the soil due to caused by residual mulching film long-term accumulation in the soil and is disliked
Change, plant growth is bad, endangers the sustainable development that crop field utilizes, and will promote China and administers soil pollution, improves the ecological environment
Global position, to practicing " green manufacturing " have important strategic importance.
20 middle of century, with the appearance of the development of plastics industry, especially agricultural plastic film, some industry prosperity states
Family covers ground using plastic film, and the production for carrying out vegetables and other crops obtains good result.Japan is earliest from 1948
Begin one's study in year utilization, and nineteen fifty-five is initially applied to strawberry covering production, and is promoted, and the Japan whole nation 1,200,000 is public within 1977
Dry crop (including vegetables) just, covered ground area more than 200,000 hectares, account for the 16% of dry crop cultivated area.It protects
Covered ground area accounts for 93% in shield ground.Japanese Terrestrial culture underglass is mostly used in output value height, the big vegetables of benefit and other economy
On crop.France in 1961 starts to try out film cultivation covering melon crop in the southeast of its this country.Italy is in nineteen sixty-five
Covered ground cultivation is carried out to chief crops such as vegetables, strawberry, coffee and tobaccos.The U.S. started to use black thin film the end of the sixties
Culture underglass cotton.Russia mainly carries out film ground culture underglass in low temperature arid season, to improve ground temperature, reduces soil
Ground evaporation.China is covered in the initial stage seventies using the flat furrow that waste film carries out small area, and planting vegetable, cotton etc. makees.
It is tested within 1978, starts within 1979 to be tested in North China, northeast, some areas in northwest and the Yangtze river basin, demonstrate, push away
Extensively.
Film-mulching technique is widely applied nearly 50 years as long as so far from later period the 1970s " do not push away and wide ",
By " White Revolution ", it is appreciated that be " white pollution " up to 20 years, plastics pollution also has 20 years time.Experts and scholars
It proposes, China is a soil and the relatively poor country of water resource, and the heat of most of agriculture district is obviously insufficient, by plastics
The soil moisture conservation of film and heat storage performance, improving the output in land area of one unit becomes the most regional production estimations of northern China
Inevitable choice.High production as plastic-film-covered cultivation is much bigger compared with the negative effect of residual film, plastic-film-covered cultivation mode at this stage and
Modern the latter time is still irreplaceable.
For the quality for improving mulch, degradability is improved, it is many with the broken and remaining research for reducing mulch,
Measures are being implemented, are being improved, and the harm of agricultural mulching residual and study on prevention have caused the great attention of people.But
It is, up to the present, almost without the report administered to the residual mulching film fragment being present in soil is seen.
Utility model content
In order to solve the above problem, the utility model is using 100% degradable regenerated fiber to be non-woven made of raw material
Cloth is carrier, makes microorganism adhering in carrier with degradable adhesive using the degradation of microorganism to environmental pollutants
On, the dedicated repair materials of degradable residual mulching film are made.Repair materials are placed into the soil, make microorganism with residual mulching film " battalion
Support ", reach residual mulching film cracking.
To achieve the above objectives, the utility model provides a kind of for administering the non-woven microorganism soil of residual mulching film harm
Earth repair materials, including carrier substrate, the carrier substrate two sides are equipped with degraded layer, and the degraded layer is coated in carrier base
The degradable adhesive layer containing microcapsules on material surface.
Above-mentioned carrier substrate be at least two layers degradable Lyocell fibers net parallel laid together, it is non-made of being pierced through needle
The fiber number of woven cloths, the Lyocell fibers is 1.1-1.3dtex, and the breadth of fibre length 35-42mm, carrier substrate are
130-150cm, substrate grammes per square metre are 20-50g/m2。
Above-mentioned degradable adhesive layer is chitosan adhesive phase, and the surface of preferably degradable adhesive layer is set as wave
Face.
Above-mentioned microcapsules are the degradable microcapsules containing degrading microorganism.
Microcapsules：Exactly seal solid, liquid or gas up for safekeeping becomes a kind of solia particle product in a kind of microencapsulation,
The material for preparing microcapsules has the substances such as chitosan, protein, lipid or starch, and microcapsule diameter can be grade to micron
Grade.
The utility model is using nontoxic, stable, good film-forming property, the carbon aquation that can be degraded, not generate secondary pollution to soil
