Water-retaining vegetation blanket

Abstract

The invention discloses a water-retaining vegetable blanket which comprises a high-strength fiber net layer, a biodegradable ecological cloth layer and a vegetation layer mixed with vegetation seeds, fertilizer, a water-retaining agent and a soil conditioner which are arrayed from top to bottom in sequence. The vegetable layer is adhered to the lower surface of the biodegradable ecological cloth layer through an adhesive, and fixing nails connected with the soil layer are arranged on four nodes of the high-strength fiber net layer per square meter. The water-retaining vegetable blanket has the advantages of low prices and rapid ecological restoration; seeds are allowed to contact with the ground directly, and slope protection of plants is achieved directly; requirements on soil quality are low; convenient and rapid construction is achieved, each person can construct 500 square meters per day, no special construction equipment is needed, construction cost is greatly reduced, and construction cycle is shortened; high survival rate is achieved, rate of vegetation can assuredly reach 80% within 90-120 days after construction, and the survival time can be more than 20 years; maintenance cost is low, maintenance is needed for first 45 days after construction, and survival is guaranteed when late precipitation reaches over 150mm.

Description

Technical field [0001] The invention relates to the field of preventing soil erosion and vegetation restoration, in particular to a water conservation planting blanket. Background technique [0002] At present, the existing structures to prevent soil erosion include Renault cushions, interlocking blocks and six-sided blocks. Among them, the Renault pad is also called the gabion pad, and the gabion pad refers to a pad-shaped engineering component composed of a machine-woven twisted hexagonal metal mesh surface whose thickness is much smaller than the length and width. Reynolds cushions are filled with block stones and other fillers and then connected into one body, becoming an anti-scouring structure mainly used for water conservancy dikes, bank slopes, Hyman, etc., with the advantages of flexibility and adaptability to foundations. Interlocking blocks, namely cement concrete interlocking block paving, is a new type of paving form. It was introduced to my country in the mid-1980s...

Problems solved by technology

[0003] However, existing structures to prevent soil erosion are often costly, and the vegetation planted on them has a low survival rate
