The wind and sand disasters are one of the main disasters in China, and especially the prevention and the control of desertification in arid and semiarid regions such as Xinjiang, inner Mongolia, ningxia and Gansu have been concerned all the time. Through research and practical application, the desertification control method combining machinery and biological phases is an effective method for controlling desertification.
The mechanical sand control measure is to arrange a sand stabilizing sand barrier, and the biological sand control measure is to directly broadcast forestation, cuttage forestation, seedling forestation and the like.
The grass grid sand barrier commonly used at present belongs to a sand prevention measure combining machinery and biology, is most mature to be applied in the sand fixation technology of China, and typical examples comprise the application of protection systems such as a charand railway, a Tarim petroleum road and the like. The method comprises using wheat straw or rice straw without grains as raw material, spreading on sand dune to form grass grid, burying grass 15-20 cm with shovel or grass grid machine, and raising two ends of grass to extend 10-20 cm beyond sand surface. However, because of severe natural conditions in desert regions, high temperature in the daytime, large temperature difference between day and night, strong wind and sand hazards, common grass grid sand barriers are easy to rot and destroy about two years, lose the sand fixing effect, and need to be repaired and made into grass grids more than two years. In addition, the demand for wheat straw is now high in various industries, and the cost thereof is increasing. Therefore, a new desertification control measure for prolonging the service life of the latticed wheat straw check sand barrier through phase change and reducing the investment cost of sand prevention and control is required to be found in the subsequent sand prevention and control.

The growth height of the sand sagebrush reaches 50-60 cm within 2 years, the root depth reaches 1-2 m, and the maintenance time is more than 3.
The vegetation sand sagebrush is positioned on the windward slope, the leeward slope and/or the hill top of the moving sand dune.
The planting direction of the sand sagebrush is vertical and/or parallel to the main wind direction.
The artemisia desertorum is planted in a square grid shape.
The sand sagebrush is sowed at the interval of 1 m multiplied by 1 m, and the sowing quantity is 1 kg/mu.
The method also comprises the following steps:
and additionally sowing sand-fixing plants in the sand sagebrush.
The sand-fixing plant comprises caragana microphylla and/or floral rods.
By adopting the technical scheme of the invention, the following technical effects can be produced:
1. the sand sagebrush is a common plant species in arid and semi-arid desert regions, and the drought tolerance of the sand sagebrush is very suitable for the growth in desertification regions. The sowing is carried out at the interval of 1 m multiplied by 1 m, only 1 kg of sowing quantity per mu is needed, the cost is low, and the method is economical and applicable.
2. The artemisia desertorum is a perennial herb plant, the growth of the artemisia desertorum is rapid, seeds can germinate in batches, seed sources are rich and easy to obtain, the growth amount of the artemisia desertorum can reach 50-60 centimeters within 2 years, and the root depth reaches 1-2 meters. As the aerial parts grow, the root system also grows, with both horizontal and vertical roots increasing.
3. Under the action of effective rainfall, the germination rate of the artemisia desertorum in the current year can reach 75 percent, the survival rate of the artemisia desertorum in the next year is about 50 percent, and the self-renewal of the seeds can prolong the sand fixing period to be more than 3 years along with the continuous germination and growth of the seeds fallen from the artemisia desertorum every year.
4. The sand sagebrush and other sand-fixing plants are reasonably matched for use, so that the soil moisture of the sand can be effectively utilized, and a favorable environment is provided for the subsequent sand-fixing plant to enter.
5. The sand-sagebrush-survival sand barrier has the advantages of low cost, simple setting method, easy operation, high survival rate and long time effect.

Detailed Description
In order to more clearly understand the embodiments of the present invention, the technical solutions of the present invention are further described by the specific embodiments in the following figures.
A method for arranging movable sand barrier of sand sagebrush in moving dune is disclosed, and its specific embodiment is shown in fig. 1-3.
FIG. 1 is a flow chart of the arrangement of the movable sand barriers of the sand dune desert wormwood in the method for implementing the invention. As shown in fig. 1, the process includes the following steps:
Step 3, uniformly broadcasting seeds of the artemisia desertorum on the soil surface in the wheat straw square sand barrier: after the wheat straw square sand barrier is paved, the sand sagebrush seeds are sown on the surface of the soil in the barrier without turning over.
Step 4, forming the sand-sagebrush movable sand barrier after the sand sagebrush grows up: in the implementation of the step, the artemisia desertorum sprouts and emerges after about 15 days after the effect of effective rainfall, then the artemisia desertorum grows to 10-15 centimeters, the maximum can reach 50-60 centimeters, the root depth can reach 1-2 meters, the wind and sand can be effectively prevented, and the timeliness is more than 3 years.
The root of the survived sand barrier of the sand sagebrush has the function of fixing the quicksand for the second time, the upper part can block the invasion of the low-layer sand flow, and the survived sand barrier of the sand sagebrush has long-term storage property.
In order to increase the survival rate and sand control effect of sand sagebrush nursery stocks, the sand sagebrush is planted on windward slopes, leeward slopes and/or the top of a sand dune by the square grid-shaped live sand barriers, the planting direction is vertical and/or parallel to the main wind direction, the sand sagebrush is sown at the interval of 1 m multiplied by 1 m, the sowing amount is 1 kilogram per mu, and the square grid-shaped live sand barriers are formed. The planting is strictly carried out according to the technical specifications, thereby ensuring the survival rate of the seeds.
In the specific implementation process, the sowing of the artemisia desertorum can be implemented on windward slopes, leeward slopes and hill tops of moving sand dunes in arid and semi-arid regions, and sand-fixing plants including caragana microphylla and/or flower sticks can be additionally sown in the planted artemisia desertorum living sand barriers.
FIG. 2 is a schematic diagram of grid lines of grass squares for vegetation grass square sand barriers according to the present invention.
Fig. 3 is a schematic diagram of the arrangement of the movable sand barriers of the sand dune flowing sand-hill sagebrush in the embodiment of the invention. As shown in figure 3, the nursery stock inside the sand barrier can be protected from the harm of sand flow due to the protection of the peripheral movable sand barrier. The sand sagebrush is reasonably matched with other sand-fixing plant species for use, and shrubs and herbs are planted in the sand barrier in a matching way, so that the reasonable utilization of the soil moisture of the sand is ensured, and the variety of the sand vegetation is increased.
The movable sand barrier in the specific implementation mode of the invention can play a role in sand fixation, is environment-friendly and economical, and has the advantages of simple method, high survival rate and long storage life.
