Production and application method of a bare cliff slope greening throwing planting bag

Abstract

The invention discloses a method for manufacturing and applying an edge slope afforesting throw-planting bag for a naked cliff. A mesh bag is prepared by directionally cultivating perennial vines and herbaceous plant pot seedlings which are high in stress resistance and wide in applicability, and weaving a polyethylene material with high tensile strength; the pot seedlings are buried into the mesh bag filled with nutritional soil in a one-piece manner and are fixed by ropes to form the throw-planting bag; the bag is fixed on the irregular trace surface of the edge slope of the naked cliff by a suspending hook type or artificial cliff embedding type method; under the moisture content of the own nutritional soil and the nitrogen fixation action of leguminous plants, the bags are arranged according to the cliff planting time and the bag planting density; vine crops can naturally grow and continuously spread, so that a longitudinally and transversely staggered green plant protection vine mesh is gradually formed on the edge slope, and the edge slope of the naked cliff is re-afforested. The manufacturing, transportation and technical requirements of the throw-planting bag are simple; construction equipment and technologies are simple; measures are adjusted to local conditions; the throw-planting bag is suitable for any place and any afforesting; throw planting is facilitated, and the survival rate of plants is high; the cost is low; the throw-planting bag can be widely applied to the naked cliff, gravel and surface-soil-free edge slope afforesting.

Description

Technical field [0001] The invention belongs to the technical field of environmental protection, and specifically relates to a production and application method of a greening and planting bag for a bare cliff side slope. Background technique [0002] Due to natural factors and social development and construction and other factors, flowing rock slopes, weir slopes, bare rock slopes, and mining areas formed on the earth. Due to their appearance, soil erosion has increased, and the environment and climate are affected. In order to restore the ecology and beautify the environment, many companies at home and abroad have invested a lot of money, manpower and material resources in the slope greening project. In recent years, a series of greening methods have been innovated, such as reinforced concrete. The sash method, the spray planting method with the guest soil, the thick-layer substrate spray greening method, as well as the application of planting bags, laying of planting blankets, ...

Problems solved by technology

[0012] Cultivate the above plants in a directional way to form seedlings in a nutrient pot, and use low-level peat, garden soil, bone meal, etc. Planting is fixed on the convex and concave places of the cliff slope to make it grow naturally. As the vine crops continue to multiply and spread, the slope gradually forms a crisscross green plant protection rattan net, so as to achieve less investment, quick effect, wide adaptability and easy application. The greening effect of the slope has not been reported in China
