Problems solved by technology

Although mangrove plants can tolerate a certain degree of periodic seawater inundation, different mangrove plants have different critical lines, exceeding their physiological limits will inevitably lead to plant death and afforestation failure

Embodiment

[0021] 1 preliminary preparation

[0022] 1.1 Dismantling fish pond facilities

[0023] The dikes and gates of the breeding ponds in the afforestation area shall be dismantled, the separated water areas shall be connected into smooth and open water bodies, and the original natural tidal state of the mudflat shall be restored.

[0024] 1.2 Site preparation

[0025] Through land preparation measures, mangrove plantation beach surface and water surface each account for 50% of the total area of ​​the afforestation planning area.

[0026] (1) leveling dike

[0027] The embankment in the planned afforestation area shall be flattened and widened to lower its elevation to 0.2-0.5m above sea level, forming a mangrove plantation beach.

[0028] (2) Filling

[0029] Through engineering measures, the areas within the dikes of the original fishing ponds on the plateau are partially filled to form contiguous and island-like beaches with continuous elevation gradient changes, forming man...

Abstract

The invention discloses a forestation method for a mangrove forest in a sandy breeding pond with high salinity. The forestation method comprises the steps of: firstly dismantling circle water gates and circle levees in the regions of the breeding pond, and enabling original separated strip-shaped and block-shaped fish pond waters to be communicated so as to form an unimpeded open water body; then through earth work measures, forming block-shaped and island-shaped beach faces with continuous elevation gradient changes in the breeding pond, so that the beach faces achieve the water depth conditions desired by the growth of the mangrove forest, and create environment suitable for the growth of the mangrove forest; constructing waterway tidal creeks during construction process in the middles of the beach faces; after forming the beach faces suitable for the growth of the mangrove forest through engineering measures, planting mangrove plants on the beach faces in an artificial planting manner; and selecting and planting the mangrove plants with extremely high salt resistance, and backfilling muddy soil to planting holes.

Description

technical field [0001] The invention relates to the technical field of mangrove afforestation, in particular to a method for mangrove afforestation in sandy culture ponds with high salinity. Background technique [0002] Mangrove is a unique evergreen shrub and small tree community on the mudflats of tropical and subtropical bays and estuaries. It has the functions of maintaining biodiversity, preventing wind and waves, promoting siltation and protecting beaches, strengthening banks and embankments, and purifying seawater. Tropical and subtropical coasts and bays with silt deposits, or alluvial saline soil or saline sandy loam at river outlets are suitable for the growth and development of mangroves. It is generally distributed in the intertidal zone between the high tide line and the low tide line. The adaptability of mangrove plants to saline soil is stronger than that of terrestrial plants. According to measurements, the salinity of the seawater at the outer edge of th...
