Method for quickly growing bryophyte crust on cross section of expressway slope

Abstract

The invention discloses a method for quickly growing a bryophyte crust on the cross section of an expressway slope. The method comprises the following steps: performing natural air drying on crust bryophytes together with very thin crust soil, and then smashing; uniformly spraying with water to wet fiber grid cells on an expressway slope, uniformly spreading the smashed soil-mixed bryophyte fragments on the cross section of a fiber grid, compacting the bryophytes with a flat tool, and covering with a plastic film; and pricking a certain number of pinholes in the film, and performing shading treatment on the film with a shading net to ensure that scattered light is received. According to the invention, the crust bryophytes are taken as basic materials, and the quick bryophyte propagation method is used for the cross section of an expressway, the cross section of mining area exploitation and other places where ecological environment of soil is destroyed, so that a bryophyte crust is formed on the surface of the soil, and the bryophyte crust can achieve the effects of rainfall interception and soil organic nutrient accumulation improvement, thereby laying a foundation for survival of advanced vascular plants in the later period.

Description

technical field [0001] The invention relates to a method for cultivating a mossy crust layer, in particular to a method for quickly cultivating a mossy crust layer on a side slope section of an expressway. Background technique [0002] The asexual reproduction of most bryophytes is mostly in the laboratory stage. Under laboratory conditions, the temperature and light are easy to control, but the scale is generally small and cannot meet the needs of large-scale planting in the wild. Contents of the invention [0003] In order to solve the above problems, the invention provides a method for quickly cultivating the mossy crust layer on the side slope section of the expressway, using the mossy plant of the crust layer as the basic material, for the places where the soil ecological environment such as the section of the expressway and the mining section of the mining area are destroyed , using the method of rapid propagation of bryophytes to form a moss crust layer on the soil ...
