Road greening plantation and water retention method

Abstract

The invention discloses a road greening plantation and water retention method. The method comprises steps that in the first ten days of March of the first year, drought-resisting grass seeds are scattered on two sides of a road; drought-resisting grasses are removed; a first trench and a second trench are dug on two sides of the road and white turnips are planted in one trench and plant straws are buried into the other trench; a soil layer between the first and second trenches is mixed with sand and then potatoes are planted therein; after three months, the overground part planted with the potatoes and the white turnips are cut; then cuboidal gardening bricks are arrayed along an extending direction of the first and second trenches and a new soil layer is paved therein; herbaceous plants and flowers are sowed on the new soil layer; in the next year, soil enclosed by the gardening bricks are deeply ploughed; then woody plants and perennial herb flowers are planted at intervals; and then the woody plants and perennial herb flowers are thoroughly watered. By the use of the road greening plantation and water retention method, water-contained and retained plant belts can be formed on slopes on two sides of the road within two years; great moisture keeping effect can be achieved; slope soil weathering and water and soil loss can be effectively avoided; and the two sides of the road can be effectively greened and beautified.

Description

technical field [0001] The invention relates to the technical field of greening on both sides of urban roads, in particular to a road greening planting water retention method. Background technique [0002] In recent years, with the development of urban construction and the continuous expansion of urban scale, the connection between cities has become more and more submerged, and more and more roads between cities have been built. Steep rock walls or soft slopes, etc., the greening protection is the difficulty of soil and water conservation. The existing greening technology mainly adopts the method of spraying and greening the slope soil protection, but this technology needs to keep watering and maintenance frequently after the slope soil greening, especially in northern China, due to the dry weather, windy, The lack of rain has greatly restricted this technology. If maintenance and watering are not carried out in time, the green substrate layer of slope protection is still v...

Problems solved by technology

The existing greening technology mainly adopts the method of spraying and greening the slope soil protection, but this technology needs to keep watering and maintenance frequently after the slope soil greening, especially in northern China, due to the dry weather, windy, The lack of rain has greatly restricted this technology. If maintenance and watering are not carried out in time, the green substrate layer of slope protection is still very easy to weather and lose, making it difficult to achieve the desired effect of greening
