Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a method for constructing roadside green spaces in coastal reclamation areas. This method employs appropriate modification measures tailored to the characteristics of different areas within the coastal reclamation zone, selects suitable plant species, and involves minimal engineering work and is simple to operate.

[0004] The technical solution adopted by this invention to solve the technical problem is: a method for constructing roadside green space in coastal reclamation areas, comprising the following steps:

[0005] 1) Based on the soil characteristics of different areas in the coastal reclamation area, the areas are divided into mudflats, terraces, and roadsides;

[0006] 2) Repairing mudflats and terraces: In the mudflat area, construct strip-shaped highlands with piled stones on both sides and mudflat soil in the middle; repair the terrace area to form a sloping terrain with higher elevation on the seaward side and lower elevation on the far-sea side.

[0007] 3) Plant arrangement: Select suitable plant species and combinations for the three areas;

[0008] 4) After applying sufficient base fertilizer to the soil in different areas, plant the selected plants accordingly;

[0009] 5) Maintenance and management.

[0010] Preferably, in step 2), the height of the strip-shaped highland is higher than the highest water level at high tide, forming a soil environment that is not soaked by seawater for a long time.

[0011] Preferably, in step 3), for tidal flats, halophytic herbaceous plants with a salt tolerance range of 10-25 g / kg are selected; for terraces, herbaceous plants and shrubs with high salt tolerance range of 4-10 g / kg are selected; and for roadsides, a combination of salt-tolerant trees, shrubs and grasses is selected.

[0012] Preferably, the selected halophytic herbaceous plants are Suaeda salsa and Suaeda salsa; the selected herbs and shrubs with high salt tolerance are Reed, Reed, and Tamarix; the roadside trees are one or more of Fraxinus chinensis, Robinia pseudoacacia, Mulberry or Malus spectabilis; the roadside shrubs are Tamarix; and the herbs are Eriocaulon buergerianum and Eleusine indica.

[0013] Preferably, in step 3), the herbaceous plants are planted by broadcasting, and the shrubs and trees are planted by transplanting seedlings.

[0014] Preferably, in step 5), after the Suaeda salsa is sown, the first loosening of the soil and weeding is carried out one week after the seedlings have fully emerged. When the seedlings are about 20cm tall, the second loosening of the soil, weeding, and topdressing are carried out. After the shrub and tree seedlings are transplanted, the soil is loosened 2-3 times in the first 1-2 years and 1-2 times per year in the third-5 years. During the growth period, attention should be paid to the prevention and control of diseases and pests.

[0015] The advantages and positive effects of this invention are: promoting ecological and landscape restoration in reclaimed areas; and adopting corresponding restoration measures and plant species according to the characteristics of different areas in coastal reclaimed areas: constructing strip-shaped highlands in tidal flat areas, selecting halophytes such as Suaeda salsa and Suaeda salsa; creating sloping terrain with higher elevation on the seaward side and lower elevation on the offshore side in terrace areas, selecting salt-tolerant herbs and shrubs such as Phragmites australis, Phragmites communis, and Tamarix chinensis; and selecting salt-tolerant trees, shrubs, and herbs along roadsides, such as Fraxinus chinensis, Robinia pseudoacacia, Mulberry, Malus spectabilis, Tamarix chinensis, Elephant Ear Grass, and Leucanthus goosegrass. This construction method involves minimal engineering work, is easy to implement, and constructs a "tree-shrub-herb" vegetation structure, creating a multi-layered landscape effect and gradually forming a stable vegetation.
