Embodiment 1

[0019] Example 1: The management mode of Microcoletheca sheath culture in indoor biocrusts

[0020] The specific cultivation steps of the management mode of Microcoleena sheathing in the indoor biological crust cultivation include:

[0021] (1) Grinding of algae seeds: pass the sand through a 0.2mm sieve, sterilize, take the dry algae seeds of Microtheca sheathes preserved in the refrigerator, mix the algae seeds and sand particles in a mass ratio of 1:4, and put them in a mortar The algal seeds are ground into a powder.

[0022] (2) Sand tray preparation: Pass the sand retrieved from the field through a 0.2mm sieve, put it into a 50cm×35cm×25cm plastic tray, and lay it flat. The thickness of the sand grains is 20cm.

[0023] (3) Inoculation: Use a watering can to grind the algae species, add distilled water to mix it, and evenly sprinkle it on the sand surface with a watering can. The inoculation concentration gradient is 0.5g m -2 , 1 g m -2 , 4g m -2 , 7g m -2 See atta...

Abstract

The invention discloses a management and utilization mode for indoor biological crust cultivation of microcoleus vaginatus. The management mode comprises the steps of: mixing microcoleus vaginatus seeds and sterilized sands in a mass ratio of 1:4, and grinding the mixture into powder; sieving sands taken from the field with a sieve of 0.2mm, spreading the sands in a plastic tray to 20cm in thickness; mixing the grinded microcoleus vaginatus seeds well with distilled water, sprinkling the well mixed seeds on the sand surface uniformly, with an inoculation concentration of 4g*m<-2>; under illumination intensity of 2000lux, subjecting the sand tray to illumination cultivation at room temperature for 16 / 8h of light / dark cultivating time; sprinkling water to the sand tray with a quantum of water sprinkling of 3L*m<-2> so as to form a biological crust by inoculation of microcoleus vaginatus in the sand tray, and sprinkling water continuously for 15d; 30d later, the biological crust can be measured with a biomass of 2.52+ / -0.19mg cm<-2> and thickness of 2.23+ / -0.62mm as well as compressive strength of 109.43+ / -11.66Pa. Thus, the management mode for indoor biological crust cultivation of microcoleus vaginatus is ascertained.

Description

field of invention [0001] The invention relates to the biological technology field of desert mosses, in particular, the invention relates to the technical field of separation and purification methods of Microcoletheca in desert biological crusts. Background technique [0002] As a product of the special environment in arid desert areas, biological crusts are organic complexes formed by bryophytes, bacteria, fungi, blue-green algae, lichens and soil. In the process of its development, biological crusts actively participate in the formation of soil, have the function of changing soil physical and chemical properties, increasing soil organic matter content, and have a significant effect on improving soil anti-erosion performance. Soil biological crust has strong stress resistance, has two physiological functions of photosynthesis and biological nitrogen fixation, and its light energy utilization rate is much higher than that of higher plants. It develops and grows in an enviro...
