Abstract

The invention relates to a plant fiber blanket for ecological protection of a side slope of a road and a preparation method of the plant fiber blanket. The plant fiber blanket comprises a lower sizingscreen, a mixed fiber layer, a carrying membrane layer, a plant growth layer, a fiber covering layer and an upper sizing screen which are successively arranged from bottom to top; the carrying membrane layer is prepared by cutting off dry wheat straws, soaking the wheat straws in water, taking the wheat straws out to dehydrate for steam explosion to obtain a steam explosion fiber material, and lapping the steam explosion fiber material and thermally pressing the same to prepare the carrying membrane layer, the thickness of which is 0.10-0.20 mm and the gram weight of which is 10-30 g / m<2>. The plant growth layer comprises plant seeds, decomposed mushroom residues, a water retainer and a compound fertilizer. The plant growth layer carrying the plant seeds moves upward integrally. The degrading rate of the carrying layer is matched with plant germination and planting time. The plant grow layer is light in weight and full in nutrient, the rate of emergence of plants is high and seedlingsare emergent uniformly, so that the fiber blanket is prevented from being jacked up and swelled. The covering speed of grass and bush plants on the slope to form level ground is high and the slope protecting effect is good.

Description

technical field [0001] The invention belongs to the technical field of road slope ecological protection, specifically relates to a plant fiber blanket used for road slope ecological protection, and also relates to a preparation method of the above-mentioned plant fiber blanket. Background technique [0002] With the rapid development of my country's economy, the demand for passenger and cargo transportation has increased sharply. In order to alleviate the transportation pressure and promote regional exchanges and integration construction, the construction of road and railway networks has been accelerated, and more and more hills and mountains have been penetrated. When building roads and railways in mountainous and hilly areas, it is necessary to excavate rock and soil, resulting in a large number of exposed slopes, which not only destroys the original landform, blocks the continuity of regional hydrology, and affects the local ecosystem, but also easily Cause soil erosion, ...
