Problems solved by technology

And the most meaningful discovery is that Sandawang lacks the adaptability to storm surges in the coastal sandy land, and it is impossible to reproduce in the coastal sandy land for a long time, so there is no need to worry that Sandawang will permanently occupy the coastal sandy land and endanger the coastal sandy land endemic plants and diversity

Embodiment 1

[0029] A multi-means restoration method for coastal sandy vegetation, the restoration method includes:

[0030] (1) Set up sand barriers

[0031] Set up a fence at the edge of the desertified coastal area, and set up a sand barrier with a porosity of 25% at the position of the water-facing slope within the fence. Set up a vertical sand barrier to bury the sand barrier in the ground, with a height of 45cm above the ground;

[0032] (6) Initial restoration of off-site soil

[0033] Turning the sandy soil, the sandy soil turning operation is to use a tiller to turn up the soil layer 30cm below the sandy ground surface, and to break the compaction of the turned up soil, and the volume ratio is 1:1:2 The guest soil prepared by mixing chernozem, chestnut soil, and black loess with the coastal sandy soil;

[0034] (7) Straw fertilizer

[0035] Lay the broken straws on the soil for natural decay and fertilize the soil for 15 days;

[0036] (4) Ridging

[0037] Ridging the fertilized soil, the dis...

[0048] (8) Initial restoration of off-site soil

[0049] Turning the sandy soil, the sandy soil turning operation is to use a tiller to turn up the soil layer 30cm below the sandy ground surface, and to break the compaction of the turned up soil, and the volume ratio is 1:1:2 The guest soil prepared by mixing chernozem, chestnut soil, and black loess with the coastal sandy soil;

[0050] (9) Straw fertilizer

[0051] Lay the broken straw on the soil for natural decay and fertilize the soil for 18 days;

[0052] (4) Ridging

[0053] Ridging the fertilized soil, the dist...

Embodiment 3

[0061] A multi-means restoration method for coastal sandy vegetation, the restoration method includes:

[0062] (1) Set up sand barriers

[0063] Set up a fence at the edge of the desertified coastal area, and set up a sand barrier with a porosity of 50% at the position of the water-facing slope within the fence. Set up a vertical sand barrier to bury the sand barrier in the ground, with a height of 45cm above the ground;

[0064] (10) Initial restoration of off-site soil

[0065] Turning the sandy soil, the sandy soil turning operation is to use a tiller to turn up the soil layer 30cm below the sandy ground surface, and to break the compaction of the turned up soil, and the volume ratio is 1:1:2 The guest soil prepared by mixing chernozem, chestnut soil, and black loess with the coastal sandy soil;

[0066] (11) Straw fertilizer

[0067] Lay the broken straw on the soil for natural decay and fertilize the soil for 20 days;

[0068] (4) Ridging

[0069] Ridging the fertilized soil with a ...

Abstract

The invention discloses a multi-means restoration method of coastal sand vegetation. The restoration method includes the steps of sand barrier setting-initial guest soil restoration-straw fertilization-ridging-earthworm introduction-astragalus huangheensis seeding-reseeding. The method adopts a plurality of ways of guest soil restoration, straw fertilization, soil structure improvement by earthworms and nodule nitrogen fixation of astragalus huangheensis to improve fertilized soil, which is beneficial to the restoration of coastal ecosystem and promotes the restoration of coastal vegetation.

Description

Technical field [0001] The invention relates to the field of ecological restoration, in particular to a multi-means restoration method for coastal sandy vegetation. Background technique [0002] Coastal sands are a sensitive ecosystem rich in endemic plants but easily disturbed. Especially in recent decades, with the continuous development of coastal tourism and aquaculture development, many coastal sands have been severely disturbed. Vegetation degradation, species loss, and coastal erosion have become very common, becoming hidden dangers restricting regional security and sustainable development. [0003] Through studying the performance and role of legume Astragalus adenophora in the process of vegetation restoration in coastal sands. The results showed that A. sphagnum has good adaptability to coastal sands, and the rapid restoration of sandy vegetation can be achieved through artificial seeding of A. sap. It was also found that Astragalus sativa can coexist with most native p...
