Greening method for vegetation module slope

Abstract

The invention belongs to the field of road greening technology, in particular to a greening method for a vegetation module slope. The method comprises following steps: 1), cleaning the slope; 2), digging a vegetation cave; 3) filling matrix or nutrient soil; 4), configuring vegetation.The technical scheme utilizes seedlings or a cutting mode to green so that greening cost of a barren mountain is recued and greening difficulty of the barren mountain is lowered. The method is utilized for afforestation in the barren mountain and easy to realize so that survival rate is greatly increased, efficiency of forest cultivation in the barren mountain is improved and forest cultivation effect is significant.In addition, disused straws are fully made use of and applied to a greening net so that straws become commercial. A new approach is created for cyclic utilization of straws in order to generate business value.

Description

technical field [0001] The invention belongs to the technical field of road greening, and in particular relates to a method for greening a vegetation module slope. Background technique [0002] With the large-scale development of highway construction, a large number of highway cutting slopes need to be restored ecologically. Due to the poor soil quality, large slope, and rapid nutrient loss on cutting slopes, it is difficult for ordinary plants to survive, and it is even impossible to carry out greening work on some slopes. In addition, if the road slope is not ecologically restored, it will appear extremely inconsistent with the surrounding natural environment. The traditional slope plant protection form uses a single plant for greening, which lacks natural beauty and does not conform to the natural vegetation evolution from an ecological point of view. Alternative regularity, ecological protection and landscape effects are poor. The vegetation restoration technology curr...

Problems solved by technology

Due to the poor soil quality, large slope, and rapid nutrient loss on the cutting slope, it is difficult for ordinary plants to survive, and some slope greening work cannot be carried out.

In addition, if the road slope is not ecologically restored, it will appear extremely inconsistent with the surrounding natural environment. The traditional form of slope plant protection uses a single plant for greening, which lacks natural beauty and does not conform to the natural vegetation evolution from an ecological point of view. Replacement law, ecological protection and landscape effects are poor

The vegetation restoration technology currently used mainly has the following problems: a single herb or shrub is used for vegetation restoration, and the vegetation in the early stage of greening cannot quickly cover the bare slope, the water and soil loss is serious, and the protection effect is not good; In terms of improvement, there is a lack of application of water- and fertilizer-retaining substrates, resulting in low survival rates and low growth rates at the initial stage of plant growth; in terms of vegetation collocation, the growth succession law of the plant ecosystem is not considered, and the community evolution of the reasonable collocation of trees, shrubs and grasses is ignored. Alternative characteristics, leading to poor stability of plant ecosystems

However, due to the limited amount of water that can be naturally retained on the steep slope land by each precipitation, the trees planted often suffer from drought due to lack of water replenishment, so the survival rate is very low. At the same time, due to the destruction of the original soil surface during the tree planting process structure, but will aggravate soil erosion

If the method of sowing is used to plant trees, on the one hand, the emergence rate of seeds is often very low due to lack of water.

On the other hand, if the seeds are sown by direct sowing, they are easy to be eaten by insects or birds as food
