Description
Technical field
It is the present invention relates to a kind of industry, the utilization method of agriculture and forestry waste, in particular to a kind of to utilize agricultural wastes
And trade waste prepares the method for cultivation matrix and the cultivation matrix of preparation.
Background technique
In recent years, domestic many large- and-medium size cities suffer heavy rain repeatly and frequency shows effectiveness factors, and " seeing sea " predicament frequency is existing, and inner city
The cost that the scene of " seeing sea " is paid is numerous wrecked life and heavy economic loss.The rainwater resource in China city
Using consciousness is weak, and extremely low to the utilization rate of natural rain resource, less than 10%, a large amount of rainwater resources are directly drained, with me
State's water scarcity forms contradiction face outstanding.In recent years, China's most cities all received the influence of haze weather, especially
It is that northern area based on Jing-jin-ji region is particularly acute.And haze weather can generate strong influence to the health of human body.With
China's urban ecological problem becomes increasingly conspicuous, and more and more industries start to seek the sustainable development for solving urban ecology in practice
The method of exhibition problem, and propose one " sponge city " of construction.And the concern and promotion of the central government further promote this
The formal formation of theory.
Important content of the roof greening as sponge city has not only conformed with sponge city and " has preferentially utilized natural drainage system
System builds Demonstration for Ecological Sanitation facility, give full play to urban green space, road, water system etc. to the receiving of rainwater, store blend slow releasing function "
Requirement, the run-off of rainwater is also reduced from source, and between having delayed the peak of rainwater current;Roof greening considerably increases
The green coverage in city can effectively absorb the harmful substance in environment.
Roof greening because its construction environment particularity, to the more demanding of its matrix, in roof greening implementation process
Most important problem is to ensure that the safety of building carrier, is primarily exactly the load for building carrier, this is just needed very strictly
Selection growth matrix.The problem of natural original soil and traditional matrices maximum is exactly matrix subsidence problems, the suction with plant to nutrient
It receives, the degradation of organic matter causes nature original soil and traditional matrices ceaselessly to reduce and sink after the completion of construction, thus needs to determine
Phase supplements matrix, or even updates matrix or even secondary construction, this will be such that the later maintenance difficulty of roof greening increases, cost
Improve in addition roof greening the later period because in maintenance difficulties and cost problem fail;And traditional matrices bulk density kicks the beam, it cannot be fine
Fixation plant, natural original soil bulk density is excessive, permeability, protect store property it is not sufficient enough, can not be protected within the scope of the load-bearing on roof
Demonstrate,prove enough plant normality growths.So natural original soil and traditional matrices are unable to satisfy the requirement of roof greening.
Research in recent years finds that existing organic culture substrate, can be to the later maintenance of roof greening due to its subsidence problems
Greatly difficult and high cost is brought, is not able to satisfy the needs of roof greening, and the sustainable thoughts with sponge city
It runs in the opposite direction.Therefore roof greening requires bulk density moderate with matrix, is both capable of fixing plant, guarantees plant in the load-bearing on roof again
Within the scope of normality grow;Nutrition is moderate, will not cause to grow too fast increase later maintenance cost because nutrition is excessively high, will not be because
Oligotrophy not can guarantee the growth of plant normality;Permeability, guarantor's storage property is good, and moisture will not in the season of not rainwater, matrix
Because evaporation rate is land and several times even tens times indoor, and frequently waters, causes the nutrient loss of matrix too fast, mends
Water supplementary fertilizer increases the cost of maintenance;In rainwater frequent season, few, increase plant cannot or will not be discharged because of extra rainwater
The time that root is ducked in drink causes plant growth impaired.
China is the country using coal as main energy sources, and the 76% of electric power is generated by coal, and the flyash that fire coal generates is total
Volume of cargo in storage becomes maximum ash discharge in the world more than 1,000,000,000 tons, but also with the increase of annual 0.8 hundred million -1 hundred million tons of speed
State.Currently, China is stored as main means to the processing of flyash with grey field, a large amount of soils are not only taken up, also will cause serious
Environmental pollution.And the comprehensive utilization of flyash, it is concentrated mainly on architectural engineering, road engineering and backfill etc., is consumed
It measures limited.Compared with industry comprehensive utilization, agricultural use has that small investment, capacity is big, demand is steady, fluctuation is small, and is not necessarily to
The advantages that purification is the comprehensive Utilization Ways for being suitble to China's national situation.
Summary of the invention

It puts container and connects the water not being trapped in bottom portion.After tested, the jet flow amount in every case is in 8.38mm/min/m2, spray in each case
30min is equivalent to extra torrential rain (rainfall 25lmm) in short-term.It records each chest and initially produces water time t1, terminate and produce the water time
T2 and water yield v1;Matrix entrapment amount (v2), infiltration rate (f) are calculated, test result is as shown in table 5, wherein
Matrix entrapment amount v2=sprinkling irrigation amount V- water yield v1
Infiltration rate f=matrix entrapment amount v2/ (cabinet cross-sectional area S* initially produces water time t1)
Above-mentioned test does three groups by the water content difference of matrix altogether, and the water content of first group of all embodiment and reference examples exists
10%, the water content of second group of all embodiment and reference examples is 30%, the water content of third group all embodiments and reference examples
50%.Cultivation matrix is simulated under the conditions of different drought, the ability and infiltration rate of the retention rainwater of matrix when encountering rainfall.
The testing result of table 5 shows that under the conditions of different drought, embodiment 1-6 has good water imbibition, can be fine
Retention rainwater.Embodiment 2-7 has good water imbibition, will not because of matrix itself water content it is low without hygroscopic;From
It is significantly different that experimental result can be seen that the water imbibition of reference examples 1 can have because of the water content of itself difference, when water content is lower than
When 30%, matrix is not hygroscopic, and moisture is directly lost, if may lead to base because plunging rain suddenly in roof greening
Matter is largely lost with rainwater, and later period water seasoning is also difficult;And the water absorption that can be seen that matrix in reference examples 2 is very small,
Water retention property is also poor, and later maintenance needs frequently watering, wastes a large amount of manpower and material resources.Embodiment 1-6 is more suitable for retaining rainwater, delays
The rain pressure caused by sewerage system that plunges is rushed, later maintenance is also time saving and energy saving.
In roof greening cultivation matrix prepared by the present invention, flyash is core matrix, and ferment mushroom slag, turf, pearl
Rock is auxiliary matrix, and flyash is inorganic matrix, is surplus materials of the coal after power plant's full combustion, and being practically free of any has
Machine matter, but containing being provided with most of mineral element of plant growth, and support plant growth, will not because environment it is severe due to
Decompose, the absorption of plant and reduce.And matrix available on the market, mostly using turf as core matrix, turf itself contains abundant
Organic matter, can be released with the growth of plant, organic matter and absorb and generate sinking, roof greening prepared by the present invention
Matrix thus is not easy to sink because of the difference of its ingredient performance and commercially available roof greening matrix.
Traditional matrices bulk density kicks the beam, and plant cannot be fixed and supported well, and using turf as primary raw material, due to turf
It containing a large amount of organic matter, in growing process, is easy to be absorbed by plants and decompose, so as to cause matrix sinking;And from
Right original soil increases the load of building since its bulk density is excessive, and safety reduces, and is unsuitable for roof planting.
