Problems solved by technology

[0007] Under natural conditions, the process of succession of desert surface vegetation from algal crusts to mossy crusts takes several decades to hundreds of years. Has great damage, leading to the acceleration of the desertification process

Embodiment 1

[0034] 1. Experiment

[0035] (1) Pretreatment of experimental raw materials:

[0036] Desert moss crust: The material is collected from the natural moss-type desert biological crust in the Shapotou area of ​​Ningxia (N 37°26′46.9”E 104°50′11.2”) at the southern end of the Tengger Desert, using PVC pipes (inner diameter 10cm, 5cm in height) were randomly sampled, and the sampling depth was 0-2cm. A total of 36 moss-type (all true moss) desert biological crust samples were collected, and the samples were collected in sealed plastic bags. After bringing the samples back to the laboratory, pick out the vigorous moss plants, remove the underground part with a blade, and then rinse the plants under tap water until there is no sand between the stems and leaves of the moss plants observed under the dissecting microscope, and finally dissect them Under the microscope, take about 5mm of the stem tip, put the taken stem tip in a container containing 0.5% sodium hypochlorite solution an...

Abstract

The invention provides a culture medium for artificial propagation expanding of desert moss. The culture medium is characterized by comprising a Hogland culture medium and a plant growth regulator, wherein the plant growth regulator is 0.4-0.6 mg / L of 6-B-A or 0.4-0.6mg / L of 2,4-D. The invention also provides a method for artificial propagation of desert moss. By means of a propagation expanding matrix of desert moss crust and research on environmental conditions, the amplification mechanism of artificial moss crust materials having biological activity and self-propagation ability and the bestenvironmental conditions are determined, artificial moss crust materials having biological activity and self-propagation ability are cultured in a room, the short-term practice demand for sand fixation of human is met, and the purpose of treating land desertification is achieved.

Description

technical field [0001] The invention relates to a culture medium for artificial propagation of desert moss and a corresponding propagation method. Background technique [0002] Desert biological crusts are formed by bacteria, blue-green algae, fungi, lichens, mosses and other groups through which mycelia, rhizoids, secretions and soil particles form "cemented" agglomerations. An organic composite layer is formed, which has a dense and unique structure. [0003] Biological crusts are widely distributed in cold and arid regions, and are a characteristic landscape on the surface of arid and semi-arid deserts. Their coverage accounts for more than 40% of the living organisms on the desert surface, and even exceeds 75% in some special habitats. The existence and development of biological soil crusts can effectively improve the surface micro-habitat, increase its soil stability and the ability to resist water erosion and wind erosion, and at the same time, it has important effect...
