Description
Technical field
The present invention relates to urban runoff biologies to be detained field, specifically a kind of plantation for rainwater storage osmosis type tree pond
Soil and its preparation method.
Background technique
With the growth of urbanization, the density of population in city is steeply risen, and constantly promotes the development of urban construction.In city
While construction makes one's way in life, problem is also following.Urban construction changes the original natural ecology in city and hydrological characteristics,
70% or more precipitation forms runoff and is discharged, and causes urban waterlogging problem.Urban runoff pollution simultaneously is to be only second to agriculture face
The second largest pollution of area source of source pollution.Atmosphere pollution, road surface pollutant enter water environment as precipitation forms runoff, cause water
Body pollution.Currently, solving relevant issues by a series of sponges and rainwater management technical measures, including Rain Garden, biology
The biology such as delaying basin, recessed greenery patches, grass-planting ecological ditch is detained facility, and rainwater storage osmosis type tree pond belongs to one of which.
The pollutant components such as road or the rainfall runoff TSS on square, heavy metal, total phosphorus, total nitrogen are higher, pass through rainwater grid
Son and pipeline, which are directly drained, to pollute downstream.By being vertically arranged and rainwater-collecting, runoff is made to initially enter infiltration of regulating and storing
Saturating type tree pond, planting soil layer therein and tree root cut down the pollutant concentration in runoff and rainwater of regulating and storing.Ecology is seeped
Thoroughly tree pond can be widely applied to by road, square, residential quarter, the ground such as industrial area, cope with frequent medium and small rainfall, can also prolong
Slow heavy rain flood peak, to alleviate urban waterlogging and pollution of area source problem.
Planting soil used by common rainwater storage osmosis type tree pond is usually Chinese garden planting soil, with other Gardens of plantation
The planting soil of object is without significant difference.Chinese garden planting soil is that the matrix of nutriment is provided for ornamental plant, but natural plantation
Soil cannot be provided sufficient nutriment to plant, sufficient oxygen can not be provided for root system of plant due to easy to harden or barren
Gas, cause plant can not normal growth, therefore the improvement of Chinese garden planting soil plays an important role plant growth.For example, specially
Sharp CN 101243764A discloses a kind of configuration method of Chinese garden planting soil, and using chrysanthemum, husky, peat and lime, chrysanthemum sand are accounted for
The 78.29~86.53% of gross weight, peat account for 16.164~17.86%, and lime accounts for 0.46~0.51%, this planting soil nutrient ratio
Example is moderate, has preferable hydrophobicity and water-retaining property, can make plant normal growth, but in rainwater storage osmosis type tree pond and
There are following obvious shortcomings for speech:
1) Chinese garden planting soil infiltration rate is not enough to be discharged the runoff that heavy rain is formed in time；
2) to Runoff contaminants without apparent removal function, on the contrary, often the nutritional ingredient in planting soil can be with water
Point loss and pollute downstream.
Summary of the invention
Technical problem to be solved by the invention is to provide one kind can guarantee plant normal growth, and osmotic effect is good, right
The good planting soil and its preparation method for rainwater storage osmosis type tree pond of Runoff contaminants removal effect.
The technical scheme to solve the above technical problems is that
A kind of planting soil for rainwater storage osmosis type tree pond includes following raw material: sandy loam 70- by weight
80 parts, 20-30 parts of coco bran, 5-10 parts of flyash and 0.5-1 parts of humus.
Preferably, each raw material is preferred by weight: 70 parts of sandy loam, 20 parts of coco bran, 5 parts of flyash and humus 0.5
Part.
Preferably, each raw material is preferred by weight: 75 parts of sandy loam, 25 parts of coco bran, 7 parts of flyash and humus 0.8
Part.
Preferably, each raw material is preferred by weight: 80 parts of sandy loam, 30 parts of coco bran, 10 parts of flyash and humus 1
Part.
Wherein, coco bran is cocoanut husk fiber dust, is coconut by-product or waste after processing, is from cocoanut husk
The pure natural organic matter medium of one kind under falling off in fiber process, through processing after coco bran be very suitable for cultivating
Plant；Sandy loam silt content is 55~85%；Flyash is the by-product of coal-fired power plant, contains a large amount of water solubility in flyash
The necessary nutrient of the crops such as silicon-calcium-magnesium phosphorus can promote plant growth, while flyash is widely used in transformation and glues again
Soil, the raw-soil, acidity and saline-alkali soil contain aluminium, ferro element in fine coal ash component, can remove phosphor in sewage element, improve total phosphorus and go
Except rate.
The invention also discloses the preparation method of the above-mentioned planting soil for rainwater storage osmosis type tree pond, including it is following
Step:
1) feedstock processing:
A. sandy loam is handled: in sunning 1-2 days after taking the sandy loam to break up, spraying fungicide is sterilized after sunning；
B. coco bran is handled: it takes the coco bran to be sent out with bubble, makes its conductivity lower than 0.5mS/cm, dried 1-2 days after dehydration,
It needs to ted 3-5 times during sunning, then spraying fungicide is sterilized；
C. flyash is handled: taking the flyash to be dried to water content 5%-8%, being then ground to partial size is 0.1-
0.2mm；
2) raw material mixes and stirs:
It successively takes the sandy loam, coco bran, flyash and humus to be added in blender, is mixed and stirred with the revolving speed of 4-6r/min
Uniformly to get the planting soil.
Preferably, fungicide used by being sterilized in step 1) to the sandy loam and coco bran is 600 times of liquid
Carbendazim.
Preferably, sterilization is carried out to the sandy loam and coco bran in step 1) and is all made of uniform sprinkling.
Preferably, coco bran described in step 1) is to wring out to continue to steep twice after immersion in 1 day with the process that bubble is sent out
Water.
Preferably, the drying temperature environment of flyash described in step 1) is 200-250 DEG C.
The beneficial effects of the present invention are:
1) the ph value of this planting soil is between 6.5-7.8, conductivity 0.6-1.1mS/cm, and infiltration rate reaches 50-
Between 150mm/h, osmotic effect is good, and rainfall runoff can be discharged in time；
2) it is 55-80% that pollutants removal rate, which is respectively as follows: COD removal rate, and TSS removal rate is 65-80%, TN removal rate
40-60%, TP removal rate 50-70%, it is preferable to runoff pollutant removal, have excellent detergent power；
3) interior porosity of this planting soil is greater than 35%, and sufficient oxygen is provided for root system of plant, and available moisture is big
In 40%, the content of organic matter can satisfy demand of plant growth less than 5%；
4) relative to traditional shade tree tree pond, water-retaining property is also stronger, can save the frequency of gard watering, reaches water-saving
Benefit；
5) configured plantation soil-structure interactions can be widely used in the shade tree pond of sponge urban project, have excellent answer
Use prospect.
