Description

Technical Field

[0001] The present invention relates to the field of ecological protection, and particularly to a method for planting vegetation in coastal wetland salt marshes and a method for treating Suaeda salsa seeds. Background Art

[0002] On June 3, 2020, the state jointly issued the "Overall Plan for Major Projects on the Protection and Restoration of Important Ecosystems across the Country (2021-2035)", emphasizing that the Yellow Sea and Bohai Sea regions are "guided by the restoration of the coastal ecosystem structure and the improvement of service functions". The "Construction Plan for Major Projects on the Protection and Restoration of the Coastal Ecosystem (2021-2035)" clearly states that "in the waters such as the southern part of Nangang, improve the ecological environment and bird habitats, and promote the natural restoration of marine biodiversity".

[0003] In the area of the wetland restoration project, which is located in the intertidal zone, the traditional planting technology of Suaeda salsa has great limitations. The ebb and flow of the tides directly act on the beach surface, severely washing away the sown seeds, resulting in a low planting survival rate.

[0004] Most of the existing methods for planting salt marsh vegetation are direct seeding. This method is suitable for land planting and is not affected by tidal scour. When this planting method is used in coastal wetlands, especially in the intertidal zone, due to the light weight of the seeds, they cannot be tightly combined with the silt during high tide, and a large amount of seeds are lost under the repeated scour of the waves, seriously reducing the seed germination rate. Summary of the Invention

[0049] Further, in step S713 of this embodiment, seeding: Use a crawler-type small flatbed cart to transport the seeds to the planting area, use foam boards as the temporary access road, and evenly place the planting bags on the tidal flat ground.

[0051] Further, preferably, step S703 of this embodiment, soaking includes: Soak the Suaeda glauca seeds in a 500mg / L potassium permanganate solution for 2h.

[0052] To ensure that the seeds can germinate normally, further, preferably, step S705 of this embodiment, soaking includes: Transfer the soaked Suaeda glauca seeds to clean water at a temperature of 18 - 22°C and soak for 24h.

[0054] Further, preferably, step S707 of this embodiment, stirring includes: Place the soaked Suaeda glauca seeds and the planting soil in an electric stirring tank in a weight ratio of 1:11 and stir to mix evenly.

[0055] Further, preferably, step S709 of this embodiment, granulation includes: Spray water during the stirring process for wetting treatment to keep the water content at 5%. Wait until all the seeds and the planting soil form granules with a diameter of about 3mm, and then stop the stirring and wetting treatment.

As Figure 6 shown, the sample of the seed planting bag formation of the present invention.

[0057] Further, preferably, the planting soil in this embodiment is selected from one or more of loam and sandy soil with uniform particles.

[0058] Preferably, the pelleted particle size of the seeds is maintained at 1-2 cm. The planting bag is made of a degradable paper bag, which is ensured to weather and rot within one week, enabling the Suaeda salsa seeds to germinate and grow normally.

[0059] The pelleted seeds and planting packages of the present invention use the guest soil as a carrier to wrap the seeds in the guest soil, enabling the seeds to retain more seeds in the planting area per unit area and reducing the loss of seeds caused by rain or wave erosion.

[0060] The planting method of the coastal wetland salt marsh vegetation of the present invention is universal, and common greening vegetation seeds can be used. However, crop seeds are excluded because crops have a certain density for normal growth.

[0061] The water content during stirring in the present invention is the water content of the spherical objects after the guest soil and the seeds are pelleted, or the water content of the particulate matter formed by granulating the guest soil and the seeds. The water content is the mass of water / the mass of the mixture. The water content in the present invention is a rough value, as long as the mixture forms pelleted particles.

[0062] During stirring in the present invention, the vegetation seeds are mixed with the planting soil in a ratio of 1:11 by weight.

[0063] The planting method of the coastal wetland salt marsh vegetation of the present invention. Method 1 can improve the seeding efficiency and make the seed distribution more uniform; Method 2 can improve the retention rate and germination rate of seeds per unit area.

[0064] Before being mixed with the planting soil, the seeds need to be soaked and germinated in a potassium permanganate solution first. After soaking, the potassium permanganate is washed off with clean water, and then the screened planting soil is mixed with the seeds. To ensure the uniformity of the seeds and the planting soil, the seeds and the planting soil are put into a stirring tank according to a certain ratio for stirring. During the stirring process, a spray bottle is used to moisten them. When the seeds and the planting soil gradually form a spherical shape (see Figure 5 ) the stirring and spraying can be stopped. In areas with severe tidal erosion, the mixed seeds are filled into degradable paper bags (see Figure 6 ). At low tide, the planting bags are thrown manually at a density of 24-36 pieces / m2. To ensure the normal growth of the seeds after germination, the paper bags need to weather and rot within one week.

[0065] To ensure the planting effect of the intertidal zone vegetation, after extensive investigation and experiments, the present invention has developed two planting methods: pelleted seeds and ecological planting packages. Since the seeds are relatively light, they will float on the water surface after being washed by the tide, and the ebb tide will carry the seeds away. The pelleted seeds and the planting bags increase the friction force through their own weight and the contact area with the soil, enabling the seeds to effectively combine with the soil, overcoming tidal erosion to a certain extent, reducing the seed loss rate, and increasing the germination survival rate.

[0066] Since 2016, Dongying City has joined hands with scientific research institutions such as the Yantai Institute of Coastal Zone Research, Chinese Academy of Sciences to carry out micro-topography transformation, restore the original ecological background environment, plant Suaeda salsa and seagrass beds using ecological planting bags, and increase the coverage of native vegetation. So far, a total of 52,000 mu of Suaeda salsa and seagrass beds have been restored, the wetland area has increased by 188 square kilometers, a growth of 12.3%.

[0067] The Tianjin Marine Ecological Protection and Restoration Project mainly focuses on natural restoration supplemented by artificial restoration. Through a series of projects such as returning aquaculture ponds to wetlands and vegetation planting, it improves the quality of the surrounding ecological environment, restores muddy tidal flats, plants Suaeda salsa using the pelleted seed method, enhances the service functions of the marine ecosystem, contributes to the carbon neutrality goal, and ensures ecological security. At present, the growth of Suaeda salsa is in good condition.

The technical scope of this application is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
