Rapid cultivating method of sand moss crust

Abstract

The invention discloses a rapid cultivating method of sand moss crust, Including the steps that a whole piece of the moss crust in a sand natural environment of a dry area is collected, a silver leaf bryum is used as a dominant species, the impurities of sand and dead leaves are sieved to be removed after soaking; the moss crust is crushed after air drying in a shade place or oven drying for 48 hours under 30 degrees centigrade; the underlying sand of the moss crust is collected as substrate and is filled in a cultivating container with the diameter being 18cm, the height being 2cm and the thickness being 1.5cm, the moss pieces are evenly spread on the substrate surface inside the cultivating container, water is added until the water content is 13.9%; the moss pieces are put into a PGX multi-stage serial intelligent illuminating incubator to constantly cultivate for 40 days, and the moss crust can be formed. The cultivating condition requirement of the moss crust is relatively simple, the technology is convenient, the cost is low, and the method can be well popularized in production application.

Description

technical field [0001] The invention belongs to the technical field of environmental engineering, in particular to a rapid cultivation method for moss crusts on sandy land. Background technique [0002] 33-52% of the world's land area is in arid and semi-arid environments. Due to the limitation of water conditions in these areas, many plants cannot survive, and biological crusts have become the main active ground cover in this area. Biological crust is an organic complex formed by the cementation of its biological components with surface soil particles through rhizoids, mycelia and their secretions. Biological components include: algae, lichens, mosses and other cryptogamous plants, as well as soil microorganisms such as bacteria and fungi. Generally, the development of biological crusts goes through three stages, algal crust stage, lichen crust stage and moss crust stage. The water change of organic components in biological crusts makes it stop physiological activities in...

Problems solved by technology

[0005] Disadvantages of the prior art: the separation of the moss leaves and the transplanting of the protonema in the above invention are difficult to operate, and the process is cumbersome, because the naturally growing moss plants are small in size and difficult to achieve in large-scale production
