Vegetation Restoration System and Method for Vegetation Restoration Using the System

Abstract

The invention provides a vegetation recovery system which comprises an exposed hillside with a certain slope or level sandy land, a water cellar arranged in a high position of the hillside or a level position higher than the sandy land, vegetation planting units laid along a sloping surface of the hillside or the sandy land lower than the water cellar, a main flow pipe and branch pipes; the vegetation planting units comprise square plastic frames, crossed four-way pipes located in the centers of the plastic frames and provided with openings on the top surfaces, and cotton yarns located at the openings of the top surfaces of the four-way pipes and extending to the side edges of the plastic frames; the four-way pipes in the centers of the adjacent vegetation planting units are mutually connected via the branch pipes; one end of the main flow pipe is connected with a water outlet at the bottom of the water cellar; and the other end of the main flow pipe is connected with the branch pipe in any vegetation planting unit.The vegetation recovery system employs the vegetation planting units in special structures, is convenient to construct and low in maintenance cost, and does not require manual sprinkling and watering, a plant survival rate is high, and after plants grow, roots of the plants can penetrate into rock or the earth surface and can exert a good water holding and soil fixation effect.The invention further provides a method for vegetation recovery of the hillside or the sandy land exposing the rock with the vegetation recovery system.

Description

technical field [0001] The present invention relates to an ecological restoration system, in particular to a vegetation restoration system, and more specifically to a system for the bare rocky hillsides caused by the construction of roads, wind farms, etc. A system of vegetation restoration. The present invention also relates to a method for recovering vegetation on exposed rocky hillsides or sandy wastelands by using the above-mentioned vegetation restoration system, so as to achieve the purpose of sand prevention, sand control and maintenance of ecological balance. Background technique [0002] In recent years, with the acceleration of my country's economic and social development, the construction of highways, wind farms, etc. is increasing, and the number of exposed slopes caused by various filling and excavation and blasting construction is increasing; the sandy wasteland is arid and semi-arid. Under the conditions of drought, wind, little rain and loose sandy surface, t...

Problems solved by technology

Though this method can allow exposed hillsides to be afforested very quickly, the problems that exist are: 1. Adopt cement to build the frame of square grass grid, the project is big, and the cost is high; 3. The soil suitable for seed growth is placed in a plastic bag, and the sprayed water or rainwater tends to flow away along the surface of the plastic bag, making it difficult to penetrate into the soil. Low; 4. There is a layer of plastic film between the soil and the hillside rock formation. After the plants grow, the roots cannot go deep into the rocks. When the typhoon comes, the plants are easily uprooted and cannot play a good role in water retention and soil stabilization. Function; 5. Because the soil needs to be transported from other places, and the thickness of the soil layer of this method is generally 10-20cm, the construction cost is very high, which makes it unable to be widely used
