Method for recovering vegetation through micropore thin films

Abstract

The invention provides a method for recovering vegetation through micropore thin films. The method comprises the operation steps that (1) a field is cleaned; (2) the corresponding micropore thin film is laid; (3) earthwork standard rooms are laid and fixed; (4) a nutrition matrix is poured; (5) plant seeds are sowed; (6) the corresponding micropore thin film is laid; (7) fixation is carried out; (8) watering, management and maintenance are carried out. The construction technology is simple, the later stage management and maintenance are convenient, continuous and effective nutrients can be provided for the growth of plants, soil moisture evaporation can be effectively restrained, the soil air permeability can be improved, the germination rate of the plant seeds can be increased, and finally the purposes of effective greening, soil improving and ecological environment improving are achieved. The method can be widely applied to recovery of vegetation of barren mountains, engineering abandon places, cities and the like.

Description

technical field [0001] The invention relates to a method for restoring vegetation, in particular to a method for restoring vegetation by using a microporous film. Background technique [0002] With the acceleration of industrial development and urban modernization, the local economy has made gratifying achievements, but it has also brought some ecological and environmental problems. The city continues to expand to the surrounding areas, and excavation, road opening, and stone removal have resulted in a large number of exposed mountains, and more than 50% of my country's land area has a large number of exposed slopes in mountains, hills, and loess plateaus, and the erosion is quite serious. Due to the poor site conditions of these exposed mountains, it is very difficult to restore the vegetation, the survival rate and preservation rate are not high, the vegetation grows slowly, the stability is poor, and the quality is low, resulting in the destruction of the vegetation l...

Problems solved by technology

Due to the poor site conditions of these exposed mountains, it is very difficult to restore the vegetation, the survival rate and preservation rate are not high, the vegetation grows slowly, the stability is poor, and the quality is low, resulting in the destruction of the vegetation landscape, the degradation and deterioration of the ecosystem, and the aggravation of hidden dangers of geological disasters. It affects the production and life of the exposed mountain and the surrounding residents, and restricts the sustainable development of the regional economy. Therefore, the vegetation restoration of the exposed mountain is very urgent

At present, the traditional recovery methods mainly include hanging nets, spray seeding, and frame protection, etc., but these technologies have some defects: the hanging net method is highly technical, including three technical systems of civil engineering, seeding engineering, and maintenance engineering, and the construction procedures are cumbersome and cumbersome. The requirements are strict, and the recovery effect is often greatly reduced due to construction reasons; the cost of spraying technology is high, the protection performance is unstable, the landscape effect is poor, the water and fertilizer retention performance is poor, it is not drought-resistant, and it is easy to weather and crack, and the later maintenance work is expensive. High; frame protection uses concrete, masonry, etc. to make the skeleton frame, which requires a large amount of stone materials, which is not conducive to slope drainage, and is prone to freeze-thaw and frost heave damage.
