Problems solved by technology

However, there are still few reports and patents on large-scale artificial cyanobacterial crust sand fixation technology
The reason is that this technology is still not suitable for mechanized construction

[0040] Example: Large-scale construction of artificial cyanobacterial crusts on the southern margin of the Tengger Desert

[0041] The construction site was chosen to be in the southern edge of the Tengger Desert, Mayor Liushui, Zhongwei, Ningxia Hui Autonomous Region. The average annual precipitation is about 180 mm, and the rainfall is mainly concentrated from May to September, with rainfall less than 2 mm accounting for more than 80% of the total rainfall.

[0042] In June 2018, the construction was carried out according to the above construction method. The construction area is full of mobile sand dunes. The construction area is 100 m *120m=12000 m 2 . In September 2018, the coverage and thickness of artificial crusts on the dune tops, interdune lowlands, windward slopes and leeward slopes were investigated. The results showed that the artificial crust cover on the dune top, interdune lowland, windward slope and leeward slope all exceeded 20%, and the interdune lowland...

Abstract

The invention discloses a mechanized artificial cyanobacteria crust culture construction process. The method comprises the following steps: a. cyanobacteria crust sampling and algae culture; b. spraying an algae solution at high pressure, the cyanobacteria after 7-10 days of culture are poured together with a culture solution into a high-pressure sprayer, and spraying the material onto the surfaceof the sand, wherein the amount of the sprayed algae solution is 2 L m-2, and a spray thickness is 0.2-0.5 mm; c. covering the surface of the sprayed algae solution is covered with a layer of green non-woven fabric and a green shade net; and d. using a disposable chopstick, branch, sand or stone to fix the shading net to prevent the net from being blown away by the wind. The construction time ofthe process is within one month before the arrival of the rainy season, and the shading net is uncovered after 3 months of construction. The process has the advantages that the mechanized constructionof an artificial cyanobacteria crust fixing sand technology is realized, and the process is simple and easy to grasp. The construction process significantly increases the formation rate of artificialcrusts, reduces labor costs and management costs, further improves the efficiency of sand prevention and sand control work in arid sand areas, and accelerates the speed and effect of sand damage control in arid areas.

Description

technical field [0001] The invention belongs to the mechanized construction field of artificial cyanobacteria crust sand fixation. The object of the present invention is to provide a kind of mechanized artificial cyanobacteria crust culture construction technology, realized the mechanized construction of artificial cyanobacteria crust sand-fixing technology, this technique significantly improved the construction efficiency of artificial cyanobacteria crust, artificial crust formation rate, It reduces the construction cost and management cost, and provides reliable technical support for accelerating the speed and efficiency of desertification land treatment in my country. Background technique [0002] Land desertification is one of the most serious ecological problems China is currently facing, and it is also the focus and difficulty of China's ecological construction. According to the monitoring results of the fifth "China Desertification and Sandification Status Bulletin"...
