[0030] In order to more clearly demonstrate the technical solution and technical effects provided by the present invention, the solution provided by the embodiment of the present invention is described in detail with specific embodiments below.

[0031] Example 1 like Figure 1 As shown, this embodiment provides a method for utilizing biological resources in abandoned sandy areas to achieve sand fixation and fertile soil growth promotion, comprising: Step 1, material preparation: dead branches produced by natural decline or renewal in sandy areas are mechanically crushed and used as the physical matrix of the present invention; Artemisia ordosica seeds are used as the raw material of biological colloid; phosphorus and potassium dissolving microbial agents are used as microbial additives; Step 2, the device used: one dry storage box and one wet storage box, and another mixing box, which is equipped with a stirrer. The mixing box is connected to a water inlet, two feed inlets, and a discharge port. The water inlet is connected to the water tank, and the feed inlet is connected to the dry and wet storage boxes respectively. The discharge port is connected to the sprayer, see Figure 2 ; Step 3: The dry storage box is used to store physical substrates, Artemisia seeds, and other seeds for vegetation restoration. The recommended mass ratio of substrate to seed is 1000:1:0.1. The wet storage box is used to store microbial agents; Step 4, when in use, add one portion (M1) of the substrate and seeds in the dry storage box to the mixing box, then add one portion (M2) of water and one portion of the microbial agent (M3), let it stand for 10 minutes, start the agitator, and stir it thoroughly for about 10 minutes; Step 5, start the discharge port and spraying device to evenly sprinkle the mixture on the sand surface.

[0032] Experimental studies have found that Artemisia ordosica seeds can produce colloids that are more than 1,000 times larger than their own when in contact with water, which can basically bind solid materials of the same mass. Microbial agents are added at a ratio of 0.2% of the solvent. In this method, M1=M2, M3=0.002M1. In the actual device production, the amount of each material is preset in advance. Keep the ratio unchanged.

[0033] After the application of this method, the seeds can basically germinate into seedlings within one month, the colloid substance can be completely degraded within one year, and the presence of microbial agents can make the dead branch crushing matrix completely degraded within two years. The vegetation coverage can be significantly increased to 30% within two years.

[0034] The method of the present invention was implemented by applying some materials in the semi-arid Maowusu Sandy Land and the arid Badain Jaran Desert. After implementation, the stability of the sand surface in both areas increased significantly. However, due to insufficient precipitation, the vegetation recovery in the Badain Jaran Desert was slow, but the sand surface could be stabilized in 2 years; due to high precipitation in the Maowusu Sandy Land, the vegetation coverage reached more than 60% in 3 years.
