Problems solved by technology

[0006] However, it also has certain disadvantages: due to the uneven sowing of grass seeds, grass seeds are easily washed away by rain, and the survival rate of grass planting is low, it often fails to achieve a satisfactory slope protection effect, resulting in gullies on the slope surface and topsoil loss. and other slope diseases, resulting in a large number of slope disease remediation and restoration projects, making this technology less used in recent years
However, the existing plant species that can be used for slope planting, such as: bluegrass, tall fescue, ryegrass, clover, etc., have high planting requirements, strict soil requirements, slow lawn formation, not drought tolerance, and maintenance costs advanced defects

Embodiment 1

[0025] This example provides a slope protection method, including:

[0026] Choose a gentle slope in the Yangtze River Basin with a slope of about 15°, plant iris + cross-river rattan, and simulate slope restoration:

[0027] (1) Firstly, land preparation, removing stones, dead branches, etc., and raking;

[0028] (2) Planting Iris;

[0029] The planting method is to transplant the seedlings, the row spacing is about 30cm, and the planting depth is about 28cm.

[0030] Before planting, the horse rush seedlings were raised first. The germinated Iris seeds are planted in a nutrient pot, 7-10 seeds are all right in each pot, and the height of the nutrient pot is 20-25cm.

[0031] Before transplanting the seedlings, water the nutrient bowl thoroughly before transplanting. After transplanting, continue to water, and then cover with soil to retain water, so you don't need to water in the future.

[0032] (3) Then planted Jiangteng between the rows of Ma Lin;

[0033] Cut the s...

Abstract

The invention relates to an ecological slope protection method. The ecological slope protection method includes: using iris and vine as planting plants to form a "horizontal + vertical" three-dimensional growth pattern on the slope. In the present invention, the iris grows fast and has well-developed root systems to stabilize the soil of the slope. With the growth of the iris, its roots gradually extend downwards, which can play a good role in shallow loose soil layers. Anchoring effect; at the same time, the strong asexual reproduction ability of Guojiangteng, the lateral growth, strong branching ability, well-developed fibrous roots and interweaving into a felt, its root system is distributed in a dense network, and a large area is intertwined and connected together, forming a A very strong root network acts as an anchor to the soil.

Description

technical field [0001] The invention relates to an ecological slope protection method, which belongs to the technical field of ecological protection. Background technique [0002] In recent years, the large-scale construction of various engineering projects, such as highway construction and construction, and large-scale mining have caused a series of environmental problems. The surrounding vegetation and soil are destroyed, further aggravating the intensity of soil erosion and landslides. [0003] The use of geotechnical engineering measures can effectively solve the problem of slope stability. For example, traditional slope engineering mainly uses measures such as mortar masonry, concrete (including reinforced concrete, steel mesh spray mortar, gabion reinforcement, etc.) permanent slope protection. [0004] Although this slope protection method "permanently" prevents soil erosion, it also "permanently" loses the possibility of vegetation recovery, destroys the harmony of...
