[0002] In the field of desertification control and ecological restoration, how to effectively and efficiently plant vegetation in sand has always been a key issue of concern to researchers and technicians. Traditional sand planting methods often require a large amount of water resources for irrigation, which not only increases the cost of planting, but is also difficult to sustain in a sandy environment with scarce water resources. In addition, the soil conditions in the sand are poor and the water retention capacity is poor, making it difficult for vegetation to take root and grow, resulting in unsatisfactory planting results.

[0003] In order to solve the above problems, a variety of sand planting technologies and devices have emerged in recent years. However, these technologies and devices often have problems such as complex structure, cumbersome operation, and high cost, and are difficult to be widely promoted in practical applications. Therefore, there is an urgent need for a device and method that is simple in structure, easy to operate, low in cost, and can effectively improve the efficiency and survival rate of sand planting.

[0017] 4. In the present invention, the provided snap-fit ​​section can make the planting block in close contact with the inner wall of the planting cube to prevent it from loosening when being carried.

[0018] 5.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1 like Figure 1-Figure 5 As shown, a three-stage seed planting cube for sandy soil without watering comprises a planting cube 1 and a planting block 2. The planting cube 1 is hollow inside and has openings at both ends. The inside of the planting cube 1 is divided into a growing section 3 and an inserting section 4 from top to bottom. The planting cube 1 is inserted into the sandy soil through the inserting section 4. The outer wall of the growing section 3 is provided with a clamping structure 9. Figure 2 As shown, the clamping structure 9 divides the inner cavity of the growing section 3 into a protection section 5 and a planting section 6 from top to bottom, and the vegetation block 2 is clamped in the planting section 6.

[0023] Further, such as Figure 2 and Figure 3As shown, the diameter of the tube wall of the insertion section 4 is smaller than the diameter of the tube wall of the growth section 3, and an inverted truncated cone-shaped clamping section 7 is provided between the insertion section 4 and the planting section 6. The bottom of the vegetation block 2 abuts against the inner wall of the clamping section 7, so that the vegetation block 2 is in close contact with the inner wall of the planting cube 1 to prevent loosening during carrying.

[0024] Further, such as Figure 1 and Figure 2 As shown, the bottom of the insertion section 4 is spike-shaped, and a plurality of circular through holes 8 corresponding to the insertion section 4 are opened on the tube wall of the planting cube 1. A plurality of circular through holes 8 are connected to the insertion section 4. When the humidity outside the tube is greater than that inside the tube, the moisture in the sandy soil will penetrate into the planting cube 1 through the circular through holes 8 to replenish moisture.

[0025] Furthermore, the clamping structure 9 is a clamping ring, which is fixedly sleeved on the outer wall of the planting cube 1. During planting, the staff holds the outer wall of the protection section 5 with their hands and inserts the planting cube 1 into the sand through the insertion section 4. During insertion, the clamping ring is used as a dividing line, and the tube body of the planting cube 1 below the clamping ring can be inserted into the sand through the insertion section 4, so that the planting section 6, the planting block 2 and the insertion section 4 are located in the sand. During the insertion process of the insertion section 4, the native sand in the sandy soil will flow into the insertion section 4 When water is injected into the inner cavity, the water is injected into the planting section 6 through the top of the protection section 5, thereby watering the vegetation block 2. After watering, the vegetation block 2 absorbs water and expands, and then fills the planting section 6 and the clamping section 7. During the germination of seeds, the roots of the seeds extend through the soil of the vegetation block to the original sandy soil, thereby fixing the original sandy soil. During growth, the protective section 5 set can reduce the soil structure of the vegetation block from being affected by wind erosion, thereby reducing the loss of nutrients and improving the survival rate of the seeds.

[0026] Example 2 like Figure 1-Figure 5 As shown, this embodiment is improved as follows based on the embodiment 1: Further, such as Figure 4 and Figure 5 As shown, the clip structure 9 is a sheet-like thin body. During production, the staff can design the style of the clip structure 9 according to aesthetics to improve the aesthetics after planting. The clip structure 9 is fixedly mounted on the outer wall of the planting cube 1. The clip structure 9 can not only serve as a reminder to the staff, but also increase the contact area with the sand surface, so that the planting cube 1 is more stable after being inserted into the sand, ensuring that it is not easily offset when blown by the wind.

[0027] Furthermore, the planting cube 1 and the snap-on structure 9 are made of degradable materials, so that the planting cube 1 and the snap-on structure 9 can gradually decompose under natural conditions, reducing the impact on the environment.

[0062] Experimental Section

[0063] Experiment 1 A sample plot was selected in the Korbi sandy land, and on November 17, 2023, the technical solutions of Example 5 and Comparative Examples 1 to 7 were used for planting. The germination rates were counted, as shown in Table 1.

[0064] Table 1 Seedling observation record of the experiment on the formula of vegetation blocks for sand control and prevention

[0065] As can be seen from Table 1, compared with Comparative Examples 1 to 7, Example 5 has significant advantages in both the emergence time and the emergence rate of six plants, namely, Lespedeza, Caragana, Haloxylon ammodendron, Caragana chinensis, Caragana chinensis, and Caragana chinensis. After 24 days, the emergence rate of Lespedeza, Caragana chinensis, Haloxylon ammodendron, Caragana chinensis, Caragana chinensis, Caragana chinensis, Caragana chinensis, and Caragana chinensis, achieving significant results. However, in Comparative Examples 1-7, the effects were affected due to the changes in the raw materials and proportions of the plant carriers.

[0066] Experiment 2 Comparative Examples 8 and 9 were planted using the method of Experiment 1. During the experiment, it was found that when the height of the protection section was 90 mm, the protection section was set too low, and the protection period was too short for the growth height of Lespedeza, Caragana, Haloxylon ammodendron, Chrysotrichum microphylla, Flower Stick, and Populus chinensis, and the survival rate of the seeds decreased after germination. When the height of the protection section of Comparative Example 9 was 110 mm, it was found in the experiment that due to the high height setting, Lespedeza, Caragana, Haloxylon ammodendron, Chrysotrichum microphylla, Flower Stick, and Populus chinensis were not sufficiently illuminated during their growth. In order to chase the sun, the branches of the seedlings were all thin and tall, the leaves were yellow, and the growth was not strong enough ( Figure 6 ).
