Problems solved by technology

But the disadvantage is that the sand control cycle is too long and the effect is slow. It usually takes 5-8 years to see the effect
On the other hand, with the rapid development of my country's economy and rising labor prices, the cost of such labor-intensive sand ...

Embodiment Construction

[0032] The basic idea of ​​the present invention is to spray the aqueous solution of lignin sand-fixing material after sowing the psammophyte seeds on the mobile sand dunes. Since the lignin sand-fixing material aqueous solution cannot be stepped on after spraying, the head of the spraying equipment should not be less than 25 meters, and the spray pressure of the tap should be controlled at 0.2-0.5MPa.

[0033] The suitable operating area should be determined according to the following climate and soil conditions:

[0034] Climatic parameters: annual precipitation is 100-350mm, of which the precipitation is not less than 50mm from May to September, the annual average temperature is 6-15 degrees, the annual minimum temperature is above -20℃, the annual average wind speed is 1-3.5 m / s, 4- The gust in May is less than 21.0 m / s.

[0035] Soil parameters: The best use area for lignin sand-fixing materials is the mobile or semi-mobile sand dunes where "sand moves in and people retr...

Abstract

The invention relates to a flow or semi-flow sand dune recover method, which comprises that: 1, based on condition and soil parameter, selecting working area; 2, via the grass mode, selecting plant kind; 3, planting seeds into working area, the first year grass and arbuscle are mixed sprayed into face of sand dune, arbor is sprayed at the bottom; 4, spraying lignin water solution at the face of working area, said lignin is crosslinker of lignin, urea-aldehyde and lignin, with solidifier. The lignin is modified into hydroxymethyl/hydroxyethylation lignin. The invention has low cost and better effect.

Description

technical field [0001] The invention relates to a method for controlling sand, in particular to a method for ecological restoration of flowing or semi-mobile sand dunes integrating sand fixing and greening. Background technique [0002] At present, the sand control methods popular at home and abroad include engineering sand control, chemical sand control and biological sand control, etc. The sand control technology introduced in the patent of the present invention actually combines the components of biology, chemistry, and engineering sand control, but take its advantages , to avoid its deficiency. [0003] A lot of research and development work has been done on chemical sand fixation at home and abroad, and good sand fixation effects have been achieved in practical applications. More than 60 kinds of chemical products for desertification prevention and control have been developed in the world, usually emulsified asphalt or emulsified crude oil, synthetic resin or organic l...
