Description

Technical Field

[0001] The invention relates to the technical field of sand fixation and prevention, and in particular to a biodegradable plant sand fixation board. Background Art

[0002] Conventional measures to prevent soil erosion generally use gravel, tarpaulin, or sowing. The use of gravel is costly and does not play a role in greening; tarpaulin is a temporary measure; the survival rate of sowing is low, especially in some areas with severe soil erosion, and it requires frequent maintenance in the later stage, which is also very costly. Sand fixation boards can achieve the effect of preventing soil erosion immediately, and from a long-term perspective, almost no human assistance is required after installation and deployment. Summary of the invention

[0003] In order to solve the problems of low plant survival rate, frequent maintenance and high cost in current methods for controlling desertification and soil erosion, the present invention provides a biodegradable plant sand-fixing board, including a sand-fixing tray, on which a plurality of sand-fixing units are arranged in an array, each of which includes a lower sand-fixing board, a nutrient solution, an upper sand-fixing board and a surface film, the nutrient solution is placed in the lower sand-fixing board, the upper sand-fixing board is used for placing seeds, and the upper sand-fixing board is fixed to the lower sand-fixing board, the seeds are in the nutrient solution, and the surface film covers the upper sand-fixing board.

[0004] Preferably, the lower sand-fixing plate is provided with an installation groove, the nutrient solution is placed in a hemispherical bowl, and the installation groove is used to place the hemispherical bowl. The hemispherical bowl is used to place the nutrient solution, which provides nutrition to the seeds for the growth of the seeds.

[0005] Furthermore, the hemispherical bowl is made of a degradable material. When the nutrient solution in the hemispherical bowl is used up, the hemispherical bowl degrades, and the degradation time can meet the complete growth cycle of the seeds, that is, the obvious structural damage occurs after the seeds are fully grown into seedlings and have the effect of fixing sand, and the nutrient solution can continue to provide nutrition for the seeds during the biodegradation process.

[0006] Preferably, a small hole is provided at the bottom of the installation groove, and the small hole is provided through the lower sand fixation plate. A 0.5 mm small hole is provided at the bottom of the installation groove, which can guide the growth of seed roots and make it easier to expand the root system in the soil during root development.

[0007] Furthermore, the upper sand-fixing plate is provided with a plurality of petals, which are spliced ​​to form the placement groove for placing the seeds, and gaps are provided between the plurality of petals, so that the nutrient solution can reach the seeds and be absorbed by the seeds.

[0008] Preferably, baffles are arranged around the surface covering film to collect rainwater, etc., and the collected water will be used for the growth of seeds.

[0009] Furthermore, the material of the lower sand-fixing board and the upper sand-fixing board is polylactic acid. The sand-fixing board is processed by using polylactic acid PLA degradable material with starch as raw material, which is pollution-free to the environment, and the degradation time can meet the complete growth cycle of seeds, that is, the obvious structural damage will not occur until the seeds are fully grown into seedlings, and it has the effect of fixing sand, and it can continue to provide nutrition for seed plants during the biodegradation process.

[0010] Preferably, the sand fixation tray is fixed in the sand by means of a stabilizing nail, the stabilizing nail comprises a connecting part and a fixing part, the connecting part is cylindrical, the fixing part is conical, and the connecting part is fixed to the larger end of the fixing part. The fixing part adopts a conical design, which is convenient for installation in some areas with hard soil.

[0011] Furthermore, in order to improve stability and facilitate soil covering the fixing portion, four stabilizing grooves are provided on the fixing portion, and the four stabilizing grooves are arranged in a cross shape.

[0012] Beneficial effects: 1. The invention has a simple structure and uses polylactic acid (PLA) degradable material with starch as raw material to process sand-fixing boards, which is pollution-free to the environment. The degradation time can meet the complete growth cycle of seeds, that is, obvious structural damage occurs after the seeds are fully developed into seedlings and have the effect of fixing sand. In addition, during the biodegradation process, the nutrient solution can continue to provide nutrition for the seeds.

[0013] 2. The sand-fixing board is divided into two layers, so it can ensure the separation of seeds and nutrient solution, which is convenient for long-term storage. The two-layer design has the functions of both seed storage and opening nutrient solution film. The seeds and nutrient solution can be in contact with each other and start to grow without any operation during the installation process, which is easy to install.

[0014] 3. The surface film can collect precipitation or irrigation water in the short term, providing a better moisture environment for plant growth.

[0015] 4. Use stabilizing nails to make it easier for the soil to adhere to the nail cap, which plays a stabilizing role and is also convenient for installation in areas with harder soil. BRIEF DESCRIPTION OF THE DRAWINGS
