The invention discloses a method for afforesting wall surfaces and side slopes with climbing-vine curtain wall, which comprises the following steps: (1) seed selection of plants: the plants having the climbing and hanging growth properties are selected; (2) planting containers are set: the planting containers are established according to the real situation and construction requirement of the slope surface; (3) filling of planting soil: the cured and finely-broken farming soil is filled; (4) supporting net racks are established and woven; (5) planting of plants: the plants having the climbing and hanging growth properties are planted with the traditional method; (6) later-period management: watering and fertilizer application are immediately carried out; (7) prevention of injurious insects: pesticide and germicide are sprayed. The method has the following advantages that the curtain wall supporting net racks are added, so the growth of the plant vines which climb upwards can be ensuredto stay at a mighty state; the nutrition supply is required to be coordinated with the plant growth; the nature of the plants is satisfied through the order coordination and scientific guidance; the later-period management of the plant is fine; and the perennation permanent-green woody Leguminosae is used, so the afforesting coverage rate is improved, the source of the plants is vast, the choice is multiple, and the construction technical method is simple and convenient.
