Description

Planting unit suitable for vegetation restoration of desert

Technical Field

The invention relates to the field of ecological restoration, in particular to a planting unit suitable for vegetation restoration of desert lands.

Background

In recent years, with the acceleration of economic and social development in China, the construction of highways, wind power plants and the like is increasing day by day, and the number of exposed slopes generated along with various filling, digging and blasting construction is increasing continuously; the desert is characterized in that under the conditions of drought, windy, little rain and loose sandy ground surface, the arid and semiarid regions destroy the fragile ecological balance due to artificial unreasonable and super-strong utilization of land and other factors, so that the phenomena of wind and sand movement and sand dune fluctuation which are main characteristics appear in the original non-desert regions. The bare side slope and desert land lose the soil matrix on which the plants grow, so the stability is poor and the water and soil loss is very serious. The loss of water and soil is likely to cause disastrous events such as landslide, debris flow and the like, and therefore, it is necessary to treat bare hillsides and desert lands. The conventional method for treating the hillside of bare rock comprises the following steps: the grid greening includes that the exposed slope is divided into a plurality of grids and is built by cement steel bars, plant seeds and soil suitable for the growth of the plant seeds are mixed and then are arranged in a plastic bag, the plastic bag is placed in the square grass grids, and the seeds are enabled to germinate and grow by means of sprinkling water or rain to the soil in the square grass grids at regular time. Although the method can make the bare hillside green quickly, the method has the following problems: 1. the square and grass grids are built by adopting the reinforced cement, so that the engineering is large and the cost is high; 2. in a dry season, watering is required to be carried out frequently in a spraying mode, time and labor are wasted, and the maintenance cost is very high; 3. soil suitable for seed growth is placed in the plastic bag, sprayed water or rainwater often flows along the surface of the plastic bag and is difficult to penetrate into the soil, and the survival rate of seeds is low; 4. the soil and the hillside rock stratum are separated by a layer of plastic film, the roots of the plants cannot go deep into the rock after the plants grow, and the plants are easy to be pulled up together with the roots when typhoons come, so that the plants cannot play a good role in water retention and soil fixation; 5. as the soil needs to be transported from other places, the thickness of the soil layer of the method is generally 10-20cm, the construction cost is very high, and the popularization and the use are difficult.
