Description
Technical field
The invention belongs to greening and environmental protection field of engineering technology, specifically, is related to a kind of urban soil dust controlling method.
Background technology
Particulate Pollution is wider to the coverage of China's urban air-quality, be most urban air pollutions it is primary because
Element, Particulate Pollution jeopardize environmental and human health impacts, it has also become the world pollutes problem, and airborne dust is to cause city Particulate Pollution
Principal element.As China's industrialization degree is deepened, dust pollution problem is serious all the more, and airborne dust problem not only causes largely to provide
Source is lost, and pollutes surrounding enviroment, influences people normally production and life.
City raised dust can be by the method for watering and lowering dust, and still, watering and lowering dust index is not effected a permanent cure, and frequently watering also can shadow
Ring traffic, also have by cover the less green net in aperture so as to reach suppress airborne dust purpose, it is done so that not only not environmentally but also
Waste of resource, cost is higher uneconomical, and the effect for suppressing airborne dust is general.
The content of the invention
For deficiency above-mentioned in the prior art, the present invention provides a kind of urban soil dust controlling method, and this method is adopted
With the design of science, extensive construction can be achieved, the effect of control urban soil airborne dust well can be reached, it is quick, into
This is low, green.
In order to achieve the above object, the solution that uses of the present invention is：
A kind of urban soil dust controlling method, comprises the following steps：(1) by 10-20 parts by weight after solid state fermentation
Stalk, the starch grafted acrylate of 2-5 parts by weight, the plant growth regulator of 1-4 parts by weight, the di(2-ethylhexyl)phosphate of 5-8 parts by weight
Hydrogen ammonium, the vegetable seeds of 20-30 parts by weight are mixed to prepare mixture；(2) obtained airborne dust liquid is diluted with water into mixture；(3)
Airborne dust liquid is sprayed to urban soil surface.
The beneficial effect of urban soil dust controlling method provided by the invention is by the stalk after solid state fermentation, to form sediment
After powder grafted propylene hydrochlorate, plant growth regulator, ammonium dihydrogen phosphate, vegetable seeds mixing plus airborne dust liquid is made in water, by airborne dust
Liquid is sprayed at the surface of urban soil, can realize that large area is sprayed, improve operability, realizes extensive construction；By solid-state
Raw material of the stalk as airborne dust liquid after fermentation, can not only twice laid, reach the effect of environmental protection, while after solid state fermentation
Stalk contains the nutrients such as abundant nitrogen, phosphorus, potassium, also containing various trace elements, nutrient can not only be provided for vegetable seeds, simultaneously
The property of soil can also be improved, improve its permeability；Starch grafted acrylate is that a kind of soaking effect absorbs water tree well
Fat, can be used as water-loss reducer, provide moisture for vegetable seeds, while starch grafted acrylate is readily biodegradable；Plant
Thing growth regulator can effectively adjust the growing process of plant；
By the stalk after solid state fermentation, starch grafted acrylate, plant growth regulator, ammonium dihydrogen phosphate, plant
Seed mixes by a certain percentage, is diluted with water obtained airborne dust liquid, and above-mentioned each raw material components play a part of coordinated simultaneously, system
Airborne dust liquid its nutrition general equilibrium, its proportioning pass through scientific design, obtained according to prepared by the raw material of proportioning preparation
Airborne dust liquid, it is possible to increase crop rooting rate.Stalk wherein after solid state fermentation can administer airborne dust, plant seed germination growth
Airborne dust can also be administered well afterwards, this method uses the design of science, and extensive construction can be achieved, can reach good control
The effect of urban soil airborne dust processed, quick, cost is low, green.
Embodiment
, below will be in the embodiment of the present invention to make the purpose, technical scheme and advantage of the embodiment of the present invention clearer
Technical scheme be clearly and completely described.Unreceipted actual conditions person, builds according to normal condition or manufacturer in embodiment
The condition of view is carried out.Agents useful for same or the unreceipted production firm person of instrument, it is the conventional production that can be obtained by commercially available purchase
Product.
Urban soil dust controlling method provided in an embodiment of the present invention is specifically described below.
A kind of urban soil dust controlling method, comprises the following steps：
(1) by stalk of the 10-20 parts by weight after solid state fermentation, the starch grafted acrylate of 2-5 parts by weight, 1-4 weights
The amount plant growth regulator of part, the ammonium dihydrogen phosphate of 5-8 parts by weight, the vegetable seeds of 20-30 parts by weight are mixed to prepare mixing
Thing；(2) obtained airborne dust liquid is diluted with water into the mixture；(3) airborne dust liquid is sprayed to urban soil surface.
Wherein, the stalk after solid state fermentation is a kind of organic material, content of organic matter very abundant, not only rich in nitrogen,
The a great number of elements such as phosphorus, potassium, micro- and various trace element in calcic, magnesium, sulphur, iron, manganese, zinc, copper, boron, molybdenum, chlorine etc. is gone back,
Stalk after solid state fermentation can decompose the mineral phosphorus in soil, and and can decomposes the mineral K in soil, discharges phosphorus, potassium etc.
Multiple nutritional components, can be persistently provide endlessly nutrient to vegetable seeds.Stalk wide material sources, cost is low, makes
By the use of stalk as raw material can twice laid, reach environmental protection effect.
Specifically, the stalk after solid state fermentation can be prepared according to following steps：(1) stalk is crushed into length is
0.5cm, in order to preferably fermentation；(2) by dry bacterium powder and water in mass ratio 1:100 are mixed to form zymotic fluid；(3) by powder
The stalk after 12 days obtained solid state fermentations of solid state fermentation, the straw after crushing are carried out after stalk, zymotic fluid, corn flour mixing after broken
The mass ratio of stalk, zymotic fluid and corn flour is 1:0.05:0.1.
Starch grafted acrylate has good water imbibition and water-retaining property, can use, can effectively press down as water-loss reducer
Moisture evaporation processed, reduce the infiltration and loss of moisture, reach the purpose of water conservation, can be that vegetable seeds carries in growth course
Supply water and divide, stimulate crop root growth and development.Starch grafted acrylate also has the purpose of degraded simultaneously, is a kind of biology
Degradable material, it is a kind of environment-friendly material.
Specifically, starch grafted acrylate is prepared according to the following steps：(1) by the starch of 5-10 parts by weight, 80-100 weights
1-1.5h is reacted in 80 DEG C of environment after the water mixing of amount part and obtains gelatinized starch, preferable starch is selected from cornstarch, cassava
