Description

Construction method of vegetation coiled material for slope protection

Technical Field

The invention relates to an installation method of a slope protection device, in particular to a construction method of a vegetation coiled material for slope protection.

Background

An artificial plant ecosystem refers to an ecosystem which is constructed and maintained by plants according to a certain requirement or requirements of human beings on the basis of natural or unnatural ecosystems. Generally, the construction of an artificial plant ecosystem is performed by constructing a device capable of controlling and cultivating the growth of plants. The construction of a plant ecosystem on the basis of a non-natural ecosystem mainly utilizes related artificial equipment to simulate the growth environment required by plants in a natural state, so that the plants can grow in the system and the circulating operation of the system is maintained.

Currently, in the field of ecological restoration of plants, there are difficulties in constructing an ecological environment suitable for plant growth. Since many regions have complex niches, the constructed plant ecological environment needs to be adapted to various and complex niches when restoring the plant ecological environment of the regions. The niche is an environment for living habitation or growth and development of organisms in a small scale, and the scales of the niche are divided according to different conditions. Particularly, in karst regions occupying the territory of China, the dimensions of the niche are about several meters. Shu Xiao of Yunnan university provides a method suitable for vegetation recovery of a specific niche by analyzing the niche of geological parks of Shilin countries in Master thesis thereof, thereby realizing preparation and recovery of a karst region on the whole. Therefore, the introduction of the niche concept is very important for how to construct an efficient plant ecological controller or device for the restoration of vegetation or the artificial cultivation of vegetation.

When constructing a plant ecological controller or device suitable for different niches, the plant needs to have the self-adaptive capacity for the specific niches. That is, this ecosystem facilitates the germination and growth of plants while allowing the plants to adapt to the natural environment in which they are located as quickly as possible. In this respect, the person skilled in the art has made some active investigations. The kyonggi school university of korea, cooperative group of schools, provides in its patent WO 2016/167440 a foamed concrete-based artificial biological soil aggregate for plant growth, which allows plants to provide sufficient moisture and plant nutrients for plant growth under soilless conditions. CN 106386086A also provides a product of moisture required for plant growth. Although CN 102577872A, CN 102960097a, the study on adaptability of slope protection plants in plant rolls, and the study on water loss characteristics of water-retaining agents in plant roll matrixes have been further explored, devices which are beneficial to plant seed germination and growth in the plant seeds can be obtained, the devices obtained in the studies need to add soil or matrixes for seed germination and growth. According to common sense, different plant seeds typically require a specific soil or replacement therefor for germination and growth. Therefore, the device is undoubtedly difficult to be applied to plant cultivation work in the region with the slope niche, and the required plant ecological controller cannot be constructed. In addition, because soil needs to be added or a substrate used as a soil substitute needs to be added, the weight of the device is usually large, and the device is high in cost when being used in a large area and is difficult to apply to a slope surface.

In view of the above, how to construct a slope protection system which is less dependent on soil or artificial substrates, low in cost, less in manual management, suitable for growth of various plants, and easy to construct and maintain is a need in the art.
