Embodiment Construction

[0040] Embodiments of the present invention will be described in detail below in conjunction with examples, but those skilled in the art will understand that the following examples are only used to illustrate the present invention, and should not be considered as limiting the scope of the present invention.

[0041] The invention discloses a method for promoting the germination of cassia seeds in the substrate of high and steep slope protection. The typical cross-sectional view of the high and steep slope protection structure is as follows figure 1 As shown, the schematic diagram of the construction process is shown in figure 2 shown, including the following steps:

[0042] 1) Pretreatment of cassia seeds, combining chemical and biological measures to break the dormancy of cassia seeds, specifically, first soak cassia seeds with potassium permanganate with a concentration of 1%-2.5% for 15-25min, then soak them with sterile water for 3- 8 times, then put in warm water at 60-...

Abstract

The invention discloses a method for promoting germination of cassia seeds in a high and steep slope protection substrate. The method comprises the following steps: breaking dormancy of the cassia seeds by combining chemical and biological measures, preparing a slope, hanging a net, preparing a base layer and a surface layer of the high and steep slope protection substrate, spray-seeding and maintaining. The method can break the dormancy mechanism of hard cassia seeds, significantly improve the germination rate of cassia seeds, overcome the problem that herbaceous plants and shrub plants cannot be conducted at the same time and cannot cooperatively grow in the current vegetation slope protection technology, and provide an adaptive environment for the germination and growth of shrub seeds in the vegetation slope protection engineering. The shrub cassia seeds have high survival rate. The construction technology is convenient and fast, the cost is reduced, meanwhile, the restoration purpose of three-dimensional greening organically combining grass and wood is achieved, and the method has important significance on ecological succession and species diversity research of slope ecological protection engineering.

Description

technical field [0001] The invention belongs to the technical field of slope protection and ecological restoration engineering, and specifically relates to a method for promoting the germination of cassia seeds in high and steep slope protection substrates in slope ecological protection engineering, without affecting the slope protection of high and steep slopes with herbal plants Improve the erosion resistance, stability, diversity and succession of vegetation communities under certain conditions. Background technique [0002] With the vigorous development of national infrastructure construction, during the implementation of roads, railways, water conservancy, electric power, mining and other projects under the intervention of manpower or machinery, engineering activities have changed the surface structure on a large scale and destroyed the spatial continuity of the ecosystem. The ecological system has been strongly disturbed, the vegetation has been destroyed in a large am...
