Problems solved by technology

The mechanical sand fixation method based on short-distance sand barriers is costly and can only work within a short distance of about 50 meters from the road, and there are many mobile sand dunes along the road, with strong wind and sand, and sand barriers tens of centimeters high , it will be buried and filled in less than 2 to 5 years, and the effective time is very short

Embodiment 1

[0027] refer to figure 1 , The sand-fixing and planting structure in the desert area provided by this embodiment mainly includes three structural layers: a solidification layer 4 , a water and fertilizer retention layer 3 and a porous growth layer 2 .

[0028] In this embodiment, hemihydrate gypsum is used as the sand-fixing agent. First, the sand-fixing agent is sprayed onto the loose sand dune surface 5, and water is sprinkled so that the sand-fixing agent penetrates into the pores of the sand grains to form a high-strength cement and obtain a solidified layer 4. Specifically, it is also possible to first fix a sand-fixing frame on the surface of the loose sand dune, and then spray the sand-fixing agent into the sand-fixing frame. The shape of the sand-fixing frame can be cross, triangle, square or some other regular or irregular shapes.

[0029] Then clay, fertilizer, water-retaining agent and hemihydrate gypsum are mixed in a weight ratio of 3:1:1:0.1, and vegetation seed...

Embodiment 2

[0033] The difference from Example 1 is that in this example, a mixture of hemihydrate gypsum and anhydrite is used as the sand-fixing agent. Among them, in the water and fertilizer retention layer, the weight ratio of clay, fertilizer, water retention agent and sand-fixing agent is 2:1:1:0.5; in the porous growth layer 2, the weight ratio of gravel, straw fiber and sand-fixing agent is 20:1:0.5

Embodiment 3

[0035] Different from Example 1, in this example, water glass is used as the sand-fixing agent. Among them, when preparing the solidified layer, water glass is sprayed onto the surface of the loose sand dunes. At this time, the sand-fixing agent can penetrate into the pores of the sand grains without sprinkling water to form a high-strength cement; in the water and fertilizer retention layer, clay The weight ratio of fertilizer, water retaining agent and sand-fixing agent is 2.5:1:1:0.2; in the porous growth layer 2, the weight ratio of gravel, straw fiber and sand-fixing agent is 15:1:0.8.

[0036] In summary, the sand-fixing vegetation structure provided by the embodiment of the present invention has the functions of sand-fixing, water retention and fertilizer conservation. Planting vegetation in the sand-fixing vegetation structure can improve the survival rate of vegetation and achieve the purpose of shady trees.

Abstract

The invention discloses a desert area stabilizing and vegetation planting structure. The desert area sand stabilizing and vegetation planting structure comprises a curing layer, a water-fertilizer keeping layer and a porous growing layer, wherein the curing layer at least comprises a sand stabilizing agent; the sand stabilizing agent is molded on the surface of a loose sand dune to form cement in order to obtain the curing layer; the water-fertilizer keeping layer at least comprises clay, a fertilizer, a water-retaining agent and the sand stabilizing agent; the clay, the fertilizer, the water-retaining agent and the sand stabilizing agent are mixed and molded on the curing layer to form the water-fertilizer keeping layer; the porous layer at least comprises gravels, straw fibers and the sand stabilizing agent; the gravels, the straw fibers and the sand stabilizing agent are mixed and molded on the water-fertilizer keeping layer to form the porous growing layer. The structure is used for planting vegetable in a desert area, the survival rate of vegetation can be increased, and the aim of making a pleasant shade of trees is fulfilled.

Description

technical field [0001] The invention relates to the technical field of desertification control, in particular to a sand-fixing vegetation structure in a desert area. Background technique [0002] my country is one of the countries with large desertification land area and serious harm in the world, especially in the northwest region of our country. Due to the severe desertification of the soil along the roads and railways built in these areas, wind and sand may pose a serious threat to the safe operation of traffic at any time. At present, due to the road or railway being buried by quicksand, some road sections have been forced to divert, and some road sections are about to be annihilated by sand. Therefore, desertification prevention and control is a major technical problem that must be overcome to ensure the safety and smooth flow of traffic facilities in this area. [0003] At present, the main measures for sand fixation along roads and railways in desertified areas are ...
