Abstract
The invention discloses artificial soil for roof greening and a preparation method thereof. The artificial soil for roof greening is characterized in that industrial and agricultural by-products produced in city production and perlite as a cultivation matrix are effectively used; and the materials are reasonably proportioned and effectively mixed into the artificial soil for roof greening under certain conditions. The artificial soil for roof greening is light, has high nutrient content, strong water retention and a low cost, satisfies roof greening demands, and is a good roof greening matrix.
Description
Technical field
The present invention relates generally to a kind of specialty and is used for artificial soil of roof greening and preparation method thereof, particularly a kind of artificial soil that utilizes the industrial or agricultural co-production.
Background technology
Roof greening refers to the greening carried out and a kind of greening form of landscape architecture on the top of buildings, structures, balcony, balcony.Along with land use for greening is more and more nervous; people begin gradually to wanting the greenery patches in the air; the development of roof greening, hanging garden is also more and more faster; the development of Urban Roof greening can effectively change the urban air view; increase city's green areas and visual green amount, significantly expand the urban afforestation space, extenuate urban heat land effect; roof greening also can extend the work-ing life of roof protective layer simultaneously, reduces to stop the roof seepage.
Relevant regulation has been put into effect in domestic city such as Shenzhen, Beijing, Shanghai, Guangzhou, Changsha etc. aspect roof greening at present, " about the notice of 3 years implementation plans of tissue establishment roof greening " put into effect in Shanghai, all roof greening projects of implementing then from 2002, often complete 1 square meter and reward 10 yuan in addition.The external technology such as roof greening, flat roof that adopt as countries such as Germany, Japan, Korea S, Britain are carried out the Urban Roof greening, and through development for many years, Japan, Korea S and the Germany technology aspect roof greening be maturation day by day.
The form of roof greening has two kinds usually, meticulous greening and extensive greening.Meticulous greening construction complexity is used in new building usually, and extensive greening construction is simple and easy, and take green as main, built architectural the greening, no matter be which kind of afforestation mode, it uses the whether suitable of matrix is all the key factor of plant survival usually.Therefore, the selection of roof greening matrix and suitable application are the keys of roof greening success.At present, using more roof greening mainly contains with matrix: the light-duty materials such as perlite, haydite, vermiculite, plant ash, cinder, but a kind of material planting effect of single administration is poor, multiple material uses simultaneously that cost is high and rational proportion storeroom is very crucial, usually needs the greening personage of specialty to study through test of many times.
We through taking a broad survey and repeatedly attempting, filter out the roof greening artificial soil take the industrial or agricultural byproduct as main raw on the basis of studying soilless culture for many years.Many compositions in the industrial or agricultural byproduct can be used as roof greening, and municipal sludge is after fermentation, and quality is light, contains higher nitrogen phosphorus potassium and organic matter; The desulfurated plaster of coal-burning power plant contains more terra alba, and quality is light, and to improving soil aggregate, improving water immersed bulk density has remarkable effect; Can use on the spot, transportation cost is low, than carrying out the many of roof greening economy with other material.The crushing straw permeability is strong, and quality is light, and very strong water-permeable is arranged, and can provide nutrient for plant-growth after becoming thoroughly decomposed in soil; Perlite is the roof greening matrix of commonly using, and water-retentivity is strong, and quality is light, very suitable being used on roof greening; The cinder soil loosening, quality is light, and physical behavior is similar to planting technique soil.
Summary of the invention
The purpose of this invention is to provide that a kind of performance is good, quality is light, cost is low, be similar to the artificial substratum of natural soils, and develop the method for utilizing industrial or agricultural byproduct configuration roof greening artificial soil.
Technical scheme of the present invention is: preferably utilize byproduct mud, desulfurated plaster, stalk, perlite and cinder soil etc. in industrial and agricultural production, after it is reached the standard of using as requested, according to the Planting Design of roof greening, each composition rational proportion is mixed.
The purpose of its invention is achieved in that
At first understand the Planting Design pattern of roof garden yet to be built, according to the requirement of each kind of plant to soil matrix, consider, rationally to each composition proportion.
The composition of artificial soil: fermentation municipal sludge 10%-25%, desulfurated plaster 5%-20%, stalk 30%-55%, perlite 25%-65%, cinder soil 15%-35%, its ratio is the mass percent under air dried condition.
The preparation method of roof greening artificial soil: with the mud oxygen consumption fermentation of sewage work, become thoroughly decomposed rear air-dry; Desulfurated plaster directly gathers from the coal-burning power plant, and is standby after natural air drying; Buy the stalk of wheat after results or corn from suburb rural, the length that is ground into 10cm after air-dry is standby; Perlite and cinder soil are directly bought or collect suitable materials for later use from the living quarters from plant area, after each material all reaches requirement, mix mixing according to the weight ratio after air-dry, namely get the artificial soil of roof greening after mixing.This artificial soil on being used in roof greening, also can be at various soil properties bad or lack without soil in the afforestation project of soil, directly puddle rear as planting technique soil.
The present invention has the following advantages:
The roof greening artificial soil that 1 the present invention makes mainly becomes with cinder local soil type by municipal sludge, desulfurated plaster, stalk, perlite, and starting material are simple and easy to, and quantity is enriched, and purchase cost is low, economy;
2 making methods of the present invention are simple, can carry out specially side's special use according to the kind of planting of plant, understood the proterties of plant to be planted, carry out the proportioning of each material according to its demand, mix as requested rear standby;
The artificial soil of 3 the present invention's preparations and the physico-chemical property of natural soils are similar, and formula can arbitrarily be regulated potential of hydrogen and the physicochemical character of soil flexibly, avoided soil salinity and alkalinity or heavy soil on the impact of plant-growth fully, the characteristic of this artificial soil can satisfy the growth needs of conventional green plants.
4 the present invention are except providing a kind of effective artificial substratum for roof greening, also the consumption for the industrial or agricultural byproduct provides a new approach, the various pollutions of avoiding byproduct in piling up and transporting, environment to be caused, the while has really been realized the recycling of industrial or agricultural byproduct.
