Method for utilizing vegetation belt to protect side slope

Abstract

The invention discloses a protecting ramp method by planting shrub in planting zone. While producing planting zone, first one to six shrub seeds are planted in planting zone by the quantity of 10-35g per square. Then several procedures such as hollowness filling, prominence clipping and so on are performed. Thereafter setting plant zone and protection are started. Here wild shrub invading growth is permitted arbitrarily. When the covering ratio of shrub is more than 90%, thin plant can be cut or pruned. While the shrub length is more than 100cm, if there is less wild grass legume seeds can be planted. The invention ensures that ramp is protected by plant zone and shrub in prophase and shrub grass in intermediate stage and anaphase in which there is no need for protection so that there are good protection efficiency and lower planting cost and so on.

Description

technical field [0001] The invention relates to a biological protection method for a slope, in particular to a method for protecting a slope by planting and irrigating vegetation belts. Background technique [0002] In the prior art, the construction of roads, mines, power stations and other projects requires the formation of a large amount of filling and excavation of slopes, and the biological protection of slopes to protect slopes and restore ecology is the first choice for slope protection methods. At present, there are many methods for slope biological protection, which can be summarized into two categories. [0003] One is the grass planting method, such as substrate spraying grass planting, hydraulic spraying grass planting, vegetation belt grass planting, etc. However, there are many defects in the biological protection of slopes: first, the grass plant community formed is in the low stage of plant succession, the effect of ecological restoration is poor, and the st...

Problems solved by technology

However, there are many defects in the biological protection of slopes: first, the grass plant community formed is in the low stage of plant succession, the effect of ecological restoration is poor, and the stability, diversity and succession of the ecosystem are poor. Its plant community is easy to degrade; second: the root system of herbaceous plants is relatively shallow, and the depth of root penetration into the slope is not enough, thus affecting the protection effect of the slope; third: poor stress resistance, because it is difficult to collect wild grass species suitable for the local area, Therefore, most of the grass seeds are artificially cultivated from outside, which requires a lot of manpower and material resources for irrigation, pruning and pest control.

Third: If the slope is not planted with grass or transplanted with shrubs, the maintenance water and natural precipitation will cause a large amount of erosion of the topsoil of the slope, seriously affecting the stability of the slope and the growth of shrubs; if the slope has been planted with grass, the transplanted shrubs will be large , the density is difficult to meet the requirements of the medium-level successional plant community dominated by irrigation, and the local wild grasses are also difficult to invade; if the density is increased or planted on demand, the vegetation of the grass will be destroyed in a large amount, resulting in a large amount of surface soil erosion on the slope.
