Embodiment 1

[0026] Select 10g of soil samples from the Junggar Basin, Xinjiang, my country, 2cm below the surface crust, mix them with sterile water, put them into a 90ml triangular flask with glass beads, vibrate for 20min, put the triangular flask in boiling water and heat it for 10min Made 10 -2 、10 -3 、10 -4 、10 -5 4 different dilutions of the soil suspension, 0.2ml of each dilution of the soil suspension was inoculated on the plate containing the bacterial beef extract peptone medium, and the medium plate was inverted and cultured in a 37°C incubator for 2 sky. Use the spore staining method to identify the cultured strains, dry and fix the cultivated thallus smear, and observe it under the oil microscope after dyeing and drying with the dye solution. The heat-resistant soil bacillus that is red; the classification of this soil bacillus is named: Bacillus sp, which was preserved in the "General Microbiology Center of China Microbiological Culture Collection Management Committee" on...

Embodiment 2

[0035] Select 10g of soil samples from the Junggar Basin in Xinjiang, my country, 6cm below the surface crust, mix them with sterile water, put them into a 90ml triangular flask with glass beads, vibrate for 20min, put the triangular flask in boiling water and heat it for 10min Made 10 -2 、10 -3 、10 -4 、10 -5 4 different dilutions of the soil suspension, 0.2ml of each dilution of the soil suspension was drawn and inoculated on the plate containing the bacterial beef extract peptone medium, and the medium plate was inverted and cultivated in a 37°C incubator for 3 sky. Use the spore staining method to identify the cultured strains, dry and fix the cultivated thallus smear, and observe it under the oil microscope after dyeing and drying with the dye solution. A red heat-tolerant Agrobacterium.

[0036] The above-mentioned Agrobacillus isolated from the soil crust was fermented on a large scale using optimized cheap liquid medium I-2. The composition of this liquid medium I-2...

Abstract

A method for controlling the flowing sand of desert by the combination of alga with bacterium includes proportionally mixing the eremophytic algae powder with Bacillus edaphicus powder, proportionally inoculating the mixture in the flowing sand of desert while sprinkling nutrients conditioning liquid, and covering by ground film.

Description

technical field [0001] The invention relates to a method for combining bacteria and algae to fix desert quicksand, in particular to a method for rapidly forming desert surface crusts for windbreak and sand fixation by using the joint action of bacillus in soil and algae in crusts. Background technique [0002] The biological crust on the desert surface is the product of the special environment in the arid region. Through object spectrum and remote sensing technology, it can be observed that about 40-60% of the desert surface is covered by this special "skin". Desert surface organisms rely on natural dew and precipitation to be evergreen all year round, and can adapt to a low-nutrient environment between minus 10°C and 60°C. They are selected as pioneer plants for sand fixation and cultivated in large areas of shifting sand, which can complement and improve the " The windbreak and sand-fixing ecological system combined with trees, shrubs and grass is especially suitable for ...
