Description
Technical Field
The invention relates to a long-acting greening method for bare mountains, belonging to the field of environmental ecological restoration.
Background
Since the reform is open, along with the continuous development of economy, mountain mining becomes one of the important links of infrastructure construction. The mountain mining and quarrying not only cause vegetation fragmentation, natural landscape destruction and biodiversity sharp reduction, but also form a bare waste land after mining, and the ecological environment is deteriorated. At present, the bionic plastic net is mostly adopted for direct covering, although the bionic plastic net has a certain beautifying effect, the bionic plastic net does not help the environmental control, and the plastic net is easy to age, so that secondary pollution is caused. The main reason for treating the bare slope where the grass cannot grow is lack of plant growth, namely lack of a substrate suitable for plant growth. Plants must rely on the growth of their roots on the soil matrix and the uptake of water and nutrients in the matrix to provide plant tissue growth. The bare slope is not provided with plant growth substrates strictly, the substrates formed completely depending on natural effects (such as atmospheric dry and wet sedimentation) are extremely long, artificial implantation or covering formation is needed, and the establishment of local ecological driving area re-greening becomes an effective and feasible method.
