Problems solved by technology

If only shrub seeds are sown, it is difficult to form a vegetation layer covering the slope in a short period of time due to the slow germination and growth of shrub seeds. A slope lacking vegetation coverage is not only prone to wind and rain erosion, but also has poor landscape effects.

Embodiment 1

[0033] Embodiment 1: foreign soil+vegetative blanket+shrub seedling transplantation

[0034] The project site is a rocky slope of an expressway in northern my country (temperate semi-arid continental monsoon climate zone, with an annual average temperature of 6.6°C and an annual precipitation of 370mm). The slope was formed by blasting and mechanical excavation, except for the top of the slope Except for a small amount of soil parent material, the original natural soil and natural vegetation have been completely destroyed, and the rocks on the slope surface are exposed, the lithology is volcanic rock, and the degree of weathering is relatively high. The orientation of the slope is 20° south by east, and the slope is about 60°.

[0035] The vegetation recovery and reconstruction of rocky slopes are carried out by spraying foreign soil + laying vegetation blanket + transplanting shrub seedlings.

[0036] The foreign soil preparation plan is: mix the local natural soil and straw ...

Embodiment 2

[0043] Embodiment 2: Alien soil+vegetative tape+shrub seedling transplantation

[0044] The project site is the abandoned mining face of a mine in northern my country (temperate semi-humid continental monsoon climate zone, with an average temperature of 11.8°C and an average precipitation of 550.3mm). The slope orientation is 10° south by west, the slope is about 50°, and there is no soil on the slope , the rocks are exposed, uneven, and the degree of rock weathering is moderate. The vegetation recovery and reconstruction of rocky slopes are carried out by spraying foreign soil + laying vegetation belt + transplanting shrub seedlings.

[0045] The foreign soil preparation plan is: mix the local natural soil and straw compost at a ratio of 7:3, and then add 5% perlite, 1% organic fertilizer, and 0.5% high-efficiency compound fertilizer to the mixture of soil and straw compost by volume. Fertilizer (nitrogen, phosphorus and potassium content: 20-20-20), 0.1% water retaining agen...

Abstract

The invention discloses a method for constructing shrub and grass plant communities on a rocky slope, which organically integrates the soil replacement technology, the surface covering technology, the planting technology, the transplanting technology and the like. The method is characterized in that firstly, an external soil layer is constructed on the surface of the rocky slope by means of net suspending and soil spraying and used as a soil foundation for plant growth, transplanting holes are reserved in the external soil layer and prepared for transplanting of shrub seedlings; secondly, plant blankets (or plant strips) are laid on the surface of the external soil layer, seeds of herbaceous plants, fertilizer for the herbaceous plants and the like are inlaid in the plant blankets (or plant strips), and accordingly, sprouting and growth of the herbaceous plants are guaranteed while coverage of the herbaceous plants is controlled, and soil water evaporation can be reduced and slope soil loss can be prevented; and thirdly, the cultured shrub seedlings are planted in the transplanting holes, competition and livability of the transplanted shrub seedlings can be improved, and the shrubs are ensured to be dominant species in the slope plant communities. By the method, slope vegetation coverage can be quickly recovered, and livability and stability of artificial plant communities on the rocky slope are improved.

Description

technical field [0001] The invention relates to a method for constructing shrub and grass plant communities on rocky slopes and an application thereof, in particular to a method suitable for building bush and grass plant communities on rocky slopes in northern China and its application. Background technique [0002] In infrastructure construction projects such as water conservancy, highways, railways, mines, and residences, a large number of exposed rock slopes are often produced. The basic characteristics of these rocky slopes are: steep slope, hard surface, no soil, no vegetation, impermeable, no water storage, and the site conditions are very bad. The emergence of rocky slopes will not only aggravate soil erosion and damage the natural landscape, but also cause adverse effects on the regional ecological environment. Most areas in northern my country (Northeast, North China, Northwest) have a semi-arid and semi-humid climate, with annual precipitation between 250-700mm. ...
