Problems solved by technology

[0006] Disadvantages of the prior art: the moss provenance used in the above invention comes from arid desert areas, and because the growth and development of moss crusts has great spatial differentiation, the research results cannot be obtained under relatively good water conditions, and soil, climate, vegetation Direct promotion and application in the Loess Plateau area where the coverage conditions are completely different from desert areas

Embodiment Construction

[0023] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] The present invention carries out comparative test to determine the optimal growth environment factor combination of mossy crust on the Loess Plateau, designs three kinds of factors, four levels of each factor (see Table 1 for details), utilizes five factors and four levels of orthogonal experiment tables (sees table for details 2) Carry out an orthogonal experiment. By regularly measuring the coverage, density and chlorophyll-a content of moss crusts, the best combination of factors for cultivating moss crusts was optimized. Coverage and density can directly reflect the growth status of mossy crusts, and chlorophyll a can reflect the biomass of mossy crusts.

Abstract

The invention discloses a rapid cultivation method for loess plateau moss crusts. The rapid cultivation method comprises the following steps: under the field natural condition, selecting well-developed moss crusts; by taking Didymodon vinealis as a dominant species, getting surface crusts by shoveling for later use, wherein the gotten surface crusts are 10mm thick; drying the collected moss crusts in the shade and removing impurities, and then, crushing with a plant crusher, and fully and evenly mixing to make moss crust seed sources; evenly spreading the made moss crust seed sources on the surface of bare loess at the inoculum concentration of 700g / m<2>; under the phytotron condition, cultivating for 40 days. According to the rapid cultivation method disclosed by the invention, through artificial inoculation and a method of setting illumination intensity, surface soil water content and the inoculum concentration, the high-cover degree moss crusts can be formed in 40 days; the rapid cultivation method disclosed by the invention is an effective method for rapidly forming the moss crusts under the indoor condition, and a reference can also be provided for the practice of the quick recovery of the loess plateau field moss crusts.

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 the Loess Plateau. Background technique [0002] Biological soil crusts (BSCs, referred to as "biological soil crusts") are organic complexes formed by soil microorganisms, algae, lichens, mosses and other plant groups and soil, and widely exist in arid and semi-arid regions. According to the main biological composition, biological crusts can be divided into algal crusts, lichen crusts and moss crusts. Among them, mossy crusts are the advanced stage of the developmental succession of biological crusts on the Loess Plateau. Because their biological components can change soil physical and chemical properties through physiological and metabolic activities, and promote soil formation and plant nutrient transformation, mossy crusts can improve soil stability. , improving soil nutrients, enhancing soil erosion resistance,...
