Embodiment 1
[0026] Example 1: Construction model of artificial algal crusts in the desert environment of Gurbantunggut Desert, Xinjiang
[0027] The present invention specifically provides a construction model of artificial algae crust in the desert environment of Gurbantunggut Desert, Xinjiang, and its specific construction steps are as follows:
[0028] (1) Selection of algal species: collect well-developed natural algal crust soil samples in the field, see attached figure 1 , ground after air drying, and then collected soil samples.
[0029] (2) Liquid culture: After passing the bare sand through a 0.2mm sieve, add 100g of bare sand per liter of medium, place it on the culture frame, and then add the ground crust soil sample prepared in the above steps to the liquid medium for cultivation, the inoculation amount It is 50g dry soil / liter medium, the culture temperature is room temperature, and the light intensity is 80μE·m -2 ·s -1 , see attached figure 2 After 3 weeks, the algae s...
Embodiment 2
[0036] Example 2: The effect test of the artificial algae crust construction model in the desert environment of Gurbantunggut Desert, Xinjiang
[0037] Specific experimental method: use the content of chlorophyll a in the soil to represent the algae biomass. For the measurement method, refer to the literature (Xie et al., 2007, Soil Biology & Biochemistry, 567-572). The total biomass of algae, the biomass of harvested algae is the product of the biomass content of algae and the soil weight of harvested algae.
[0038]
[0039] The construction model of the artificial algae crust in the desert environment of the Gurbantunggut desert in Xinjiang provided above can rapidly multiply the algae species. The specific analysis is as follows:
[0040] 1) The natural algae crust collected from the field, the sampling depth is 1cm, and its bulk density is 1.744±0.068g cm -3 , that is, at a depth of 1cm, 1cm -2 The algal crust weight of the area was 1.744 ± 0.068 g. The average alg...
