Test facility for screening and cultivating ecological restoration clonal plants in quarry

Abstract

The invention discloses a test facility for screening and cultivating ecological restoration clonal plants in a quarry, and relates to the technical field of plant clone screening. The test facility comprises a first simulation pool, a second simulation pool arranged in the first simulation pool, a plurality of n-shaped support frames and a light-transmitting plastic greenhouse; a plurality of notches are formed in the periphery of the second simulation pool; and the multiple n-shaped support frames are installed on the first simulation pool in parallel, the light-transmitting plastic greenhouse wraps the outer sides of the multiple n-shaped support frames, a closed space is formed by the light-transmitting plastic greenhouse and the first simulation pool, a greenhouse door is arranged on the side face of the light-transmitting plastic greenhouse, a wind shielding curtain is installed on the greenhouse door, and return pipes are laid at the bottom of the first simulation pool and the bottom of the second simulation pool respectively. According to the test facility, the climatic indexes such as the surrounding soil environment of waste land and the periphery of the quarry and the air temperature, the ground temperature and the relative humidity in the growth environment can be simulated, the plants suitable for ecological restoration of the quarry are screened out through cultivation, the ecological restoration period of the quarry is shorter, and a restored ecological system is more stable and continuous.

Description

technical field [0001] The invention relates to the technical field of plant clone screening, in particular to a test facility for screening and cultivating cloned plants for quarry ecological restoration. Background technique [0002] Due to the development of the economy and the improvement of modernization, the development and utilization of mineral resources by human beings is also increasing day by day. Although the quarrying of mountains has greatly met the needs of people's material production, the quarrying of mountains is generally accompanied by the destruction of vegetation. The soil is generally poor, shallow, low in nutrient content, and plants grow slowly, so once the plants are destroyed, there will be consequences that cannot be restored for decades or even hundreds of years. More importantly, forest vegetation will be cut down to a certain extent. It will change the original ecological structure to a certain extent, leading to the disappearance of a large nu...

Problems solved by technology

In the past, the traditional ecological restoration of quarries was often keen to introduce fast-growing species for short-term effects, resulting in vegetation degradation and ecosystem instability in the later stage of the introduction of vegetation. These problems are mainly due to lack of theoretical research and blind pursuit of short-term economic benefits. , caused by not respecting the laws of natural development
