Embodiment Construction

[0031] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0032] Such as figure 1 As shown, an ecological bag for agricultural waste mixed with immobilized denitrification bacteria for slope protection includes a bag body 5, and the bag body 5 is mainly composed of air-permeable and water-permeable materials. The bag body 5 is mainly filled with agricultural waste, plant seeds 2, plant soil 3 and water retaining agent, and nitrogen-removing bacteria 1 are fixed on the agricultural waste. Agricultural wastes are mainly biodegradable agricultural wastes such as rice straw, corn cob, loofah or straw, among which, rice straw, loofah and straw are trimmed into 6mm-8mm long crushed matrix, and corn cob is trimmed into 5×5×5mm 3 The volume of the matrix is ​​small cubes, and the volume of the agricultura...

Abstract

The invention discloses an agricultural waste / immobilized denitrifying bacteria mixed ecological bag and system for slope protection. Agricultural wastes, plant seeds (2) and plant growth soil (3) are added into the ecological bag. Denitrifying bacteria are immobilized on the agricultural wastes, medium sand and coarse sand are added into the plant growth soil, and plants (4) are grown on the bag body (5). The ecological bag system is mainly formed by alternately piling ecological bags 1 (51) and ecological bags 2 (52); a crude cotton rope (7) is clamped among each layer of the ecological bags and between every two ecological bags; and a soft material pad (6) is clamped between every two ecological bags 1 on the same layer. The agricultural wastes are recycled and combined with the immobilized denitrifying bacteria to enhance the water purification functions of the aquatic plants and microbes, thereby promoting the ecological restoration of the aquatic environment.

Description

technical field [0001] The invention relates to the field of ecological slope protection, in particular to an ecological bag and system for mixing and immobilizing denitrification bacteria with agricultural waste for slope protection. Background technique [0002] At present, the research on the ecological bag slope protection technology mainly stays in two aspects: one is the research on the safety and stability of the slope protection, such as the geogrid reverse-wrapped ecological bag, and each layer of the ecological bag is equipped with three-dimensional drainage when stacked. The connecting buckle connects the ecological bag body into a whole, forming a stable triangular internal friction locking structure; the second is the research on the landscape greening effect of the ecological bag and the plant restoration and purification of the water body. In order to make the ecological bag slope protection plants grow densely, in order to obtain better results The water puri...
