Embodiment 1

[0025] A kind of afforestation method of high salinity deep water beach mangrove, comprises the steps:

[0026] (1) Soil preparation: On the high-salinity deep-water beach, a rectangular ridge with a width of 10m is formed along the direction parallel to the coastline. The height of the ridge is equal to the height of the sea level, and the distance between two adjacent ridges is 10m; near the sea The outermost ridge is 0.1m higher than the other ridges; each ridge is provided with a waterway perpendicular to the ridge every 90m, and the waterway is 10m wide (as shown in Figure 1);

[0027] (2) Planting: After the ridging is completed, in June of each year, a mixture of fast-growing tree species and slow-growing tree species is selected, and the hypocotyl seedlings are directly inserted or planted in nutritional bag seedlings. The planting depth of the hypocotyl seedlings does not exceed the seedling length. 2 / 3 of the plantings are planted with a row spacing of 0.5-2m and a p...

Embodiment 2

[0032] A kind of afforestation method of high salinity deep water beach mangrove, comprises the steps:

[0033](1) Soil preparation: On the high-salinity deep-water beach, a rectangular ridge with a width of 15m is formed along the direction parallel to the coastline. The height of the ridge is 0.1m higher than the sea level, and the distance between two adjacent ridges is 12m. ; The ridge belt on the outermost edge of the sea is higher than other ridge belts by 0.2m; each ridge belt is provided with a waterway perpendicular to the ridge belt every 100m, and the waterway width is 15m (as shown in Figure 1);

[0034] (2) Planting: After the ridging is completed, in July of each year, a mixture of fast-growing tree species and slow-growing tree species is selected, and the hypocotyl seedlings are directly inserted or planted in nutritional bag seedlings. The planting depth of the hypocotyl seedlings does not exceed the seedling length. 2 / 3 of the plantings are planted with a row...

Embodiment 3

[0039] A kind of afforestation method of high salinity deep water beach mangrove, comprises the steps:

[0040] (1) Soil preparation

[0041] Through the engineering measures of excavation and filling, ridges are raised in strips to raise the beach surface, forming a pattern of intervals between ridges and waterways. The width of the raised ridges is 15m, and the width of the waterways is 15m. The water outlet with a width of 20m forms a water channel perpendicular to the direction of the coastal zone, so as to facilitate the tidal water flow in the construction area. The height of the ridge surface should be 0.3m higher than other ridge surfaces to alleviate the impact of wind and waves. In the project implementation area, the area to be planted with mangroves and the water surface account for 50% each. Use the water grabber to dredge mud from both sides of the ridge belt, and fill it to the ridge belt that needs to be raised (as shown in Figure 1).

Abstract

The invention relates to the technical field of forest plating, and particularly relates to a method for planting a mangrove forest in a high-salinity deepwater sea beach. The method comprises the following steps: (1) preparing land; (2) planting; and (3) maintaining and managing the forest. Because no natural distribution of the mangrove forest exists in the deepwater sea beach, the mangrove forest cannot be successfully planted by adopting a conventional method; the mangrove forest can be planted in the high-salinity deepwater sea beach by adopting the method disclosed by the invention, the distribution area of mangrove forest wetland resource in a coastal region of South China is enlarged, the ecological function of protecting the coast by the mangrove forest is given a full play; water channels coexists in a mangrove forest restoration area, and thus a diversified environment is created so that a diversified living space can be provided for wildlife; meanwhile, in a mangrove planting area of the deepwater sea beach, by using the water channels in the mangrove forest, a natural ecological cultivating system in which the mangrove forest and the fishery industry coexist can be established, and the sustainable healthy development of the aquaculture industry in a coastal community is effectively promoted.

Description

technical field [0001] The invention relates to the technical field of afforestation, in particular to a method for mangrove afforestation on a high-salinity deep-water beach. Background technique [0002] Mangroves are woody plant communities that grow in the intertidal zone of tropical and subtropical coasts. They are an important part of the coastal protection forest system. They are known as "sea forests". natural disasters such as typhoons. The construction of mangroves can save a lot of expenses for building and maintaining coastal dams, and is an economical and effective ecological protection measure. [0003] Mangroves are periodically inundated by seawater, usually with longer exposure than inundation. Not all intertidal areas can grow mangroves. When the beach surface is submerged in sea water for too long and the exposure time is too short, mangroves cannot grow. Mangroves are most suitable for growing in estuaries or harbor areas, supplemented by fresh water f...
