Abstract
The invention relates to a raising dust control method via desert alga. The method concretely comprises the following steps of (1) adding nitrogen phosphorous and potassium compound fertilizer into desert alga water with quality concentration of 3 to 8% to acquire desert alga liquid, (2) pouring the desert alga liquid acquired in the first step on the ground surface and spraying the same with 1500 to 2500ml/m<2>, and then spraying 3 to 5 times each month until biological crust is formed, and (3) supplying water to the ground surface covered with the desert alga liquid each two days with the amount of 1500 to 2500ml/m<2> for each time. The raising dust control method can be applied to areas with dry ground surface and containing raising dust after drought alga spraying. After the spraying, biological crust is formed, raising dust can be controlled and water evaporated quantity can be reduced; carbon sequestration function is enhanced and oxygen releasing amount is increased; surface drainage is purified and infiltration capacity is increased and underground water can be conserved; and the exposed and deteriorated ground surface can be changed into a dust collector, so soil structure can be changed and organic content in the soil can be improved.
Description
Technical field
The present invention relates to a kind of method that desert algae controls airborne dust.
Background technology
At present, the common airborne dust weather in the north of China, especially in spring, boundless loess brings harmful effect to the life of the mankind and health.Because modern progress is rapid, industrialized fast development, and the further raising of human life quality, the quantity of private car is increasing, and the quality of the air caused thus day by day declines.Haze weather is attacked again and again, and therefore a kind of method of necessary invention or technology can control airborne dust.
In prior art, CN1282511 discloses the fixing means of a kind of desert algae to drift sand, and it is plastic mulching, separate drift sand, algae kind is fixed the sand in access, and every morning takes off film, afternoon press mold, execute weekly agricultural composite fertilizer once, bare area is pricked and is established straw checkerboard barrier, inoculation, water, use composite fertilizer weekly, directly access bacterial classification in Cao's lattice, use composite fertilizer.Desert algal crust can be obtained after 20-40 fills out, reach the effect of fixing the sand.The method is for having fixed the sand good curative effect.The more bibliographical information method that desert is fixed the sand, but do not have at present bibliographical information how to utilize bioanalysis to around thicker, the Industrial Stoves of drifting along, around airborne dust operation, around construction site and the living area of people carries out dust controlling.
Summary of the invention
The object of the invention is to the defect overcoming prior art, provide a kind of desert algae to control the method for airborne dust, its can time earth's surface form biological breadcrust, effectively control airborne dust.
To achieve these goals, the technical scheme taked of the present invention is as follows:
Desert algae controls a method for airborne dust, specifically comprises following operation:

(2) desert algae liquid covers
Initial stage covers: the desert algae liquid that step (1) obtains is carried out ground mulching, by 1500-2500ml/ rice
2spray;
Later stage covers: cover spray method by the initial stage and enter later stage covering sprinkling, spray and be spaced apart 7-10 days, spraying number of times is 3-10 time;
(3) final-period management
Moisturizing is every three days carried out to the earth's surface after carrying out the covering of desert algae liquid, each moisturizing 1500-2500ml/ rice
2.
What the later stage covered and in earlier stage covered is spaced apart 7-10 days.
Further, in the desert algae liquid in described operation (1), the mass concentration of nitrogen-phosphorus-potassium compound fertilizer is 5%.
Further, the earth's surface in described operation (2) refers to that surface humidity is the earth's surface of 2-10 at 0%-6%, pH.
Further, the earth's surface in described operation (2) refers to surface humidity to be 5%, pH is the earth's surface of 7.
Further, also comprise operation (4), earth's surface after forming biological breadcrust is planted by spraying grass-seed flushing liquor, described grass-seed is selected from prairie milk vetch or Bermuda grass seeds, described grass-seed flushing liquor is contain the aqueous solution or the desert algae liquid that grass-seed concentration is 0.375Kg/L, and fountain height is every square meter 1500-2500ml.
Desert algae source used in the present invention
Compared with prior art, the beneficial effect acquired by the present invention is as follows:
Control dust dispersion method provided by the invention utilizes the raw algae of drought to spray earth's surface drying and the area of easy airborne dust.Make earth's surface form biological breadcrust, control airborne dust, reduces evaporated quantity of water, strengthens solid carbon function and oxygen emission, purification surface drainage, increasing infiltration capacity, recharging groundwater.The earth's surface of exposed deterioration can be transformed into " the earth dust catcher ", change the structure of soil.Increase soil with organic matter content, reduce rainwash, prevent erosion.The algae sprayed can not have an impact to the health of the mankind.
The method that the present invention controls airborne dust can replace plastic sheeting for farm use, improves soil and drought resisting, can produce biological feedstuff.
Can be used in around thicker, the Industrial Stoves of drifting along by inventing the technology of control airborne dust technology provided, around airborne dust operation, around construction site, add spray Local grass-seed, reach and control airborne dust effect.
