Embodiment 1

[0048] In a tidal flat (length 40m, width 10m) without wild mangroves, there are about 30 days a year with a high wind speed of 100-150km / h, the distance between high tide line and low tide line is 8m, and the bottom is sediment.

[0049] Excavate mangrove seedling planting holes at selected locations;

[0050] The mangrove seedlings are implanted in the planting holes, and three layers of protective sandbags are piled up on the planting seedlings in sequence, and then covered and compacted with silt or gravel or sand, wherein the first layer of maintenance sandbags is organic fertilizer-gravel sandbags, The second layer of maintenance sandbags is shell-sand-soil sandbags, and the third layer of maintenance sandbags is at least one of silt sandbags or other sandbags. According to this method, three layers of mangrove plants of different varieties are planted from the low tide line to the high tide line to form a planting area. Two rows of paulownia trees and columbine soil are...

Embodiment 2

[0057] In a tidal flat (length 20m, width 11m) in a coastal leisure belt, the maximum wind speed is 100-120km / h for about 45 days a year, the distance between high tide line and low tide line is 10m, and the bottom is mainly sand, mud and gravel. .

[0058] Excavate mangrove seedling planting holes at selected locations;

[0059] The mangrove seedlings are implanted in the planting holes, and three layers of protective sandbags are piled up on the planting seedlings in sequence, and then covered and compacted with silt or gravel or sand, wherein the first layer of maintenance sandbags is organic fertilizer-gravel sandbags, The second layer of maintenance sandbags is shell-sand-soil sandbags, and the third layer of maintenance sandbags is at least one of silt sandbags or other sandbags. According to this method, 3 layers of mangrove plants of different varieties are planted from the low tide line to the high tide line to form a planting area. Two rows of sea mulberry and cochi...

Embodiment 3

[0067] In a tidal flat (length 100m, width 4m) facing the wind and waves, the maximum wind speed is 100-120km / h for about 30 days a year, the distance between the high tide line and the low tide line is 4m, and the bottom is mainly silt and gravel. .

[0068] Excavate mangrove seedling planting holes at selected locations;

[0069] The mangrove seedlings are implanted in the planting holes, and three layers of protective sandbags are piled up on the planting seedlings in sequence, and then covered and compacted with silt or gravel or sand, wherein the first layer of maintenance sandbags is organic fertilizer-gravel sandbags, The second layer of maintenance sandbags is shell-sand-soil sandbags, and the third layer of maintenance sandbags is at least one of silt sandbags or other sandbags. According to this method, 3 layers of different species of mangrove plants are planted from the low tide line to the high tide line to form a planting area. The low tide line area is planted ...

Abstract

The invention belongs to the technical field of mangrove forest planting, and provides a method for planting the mangrove forest in the coast intertidal zone stormward face and a fixing device. The method comprises the following steps that mangrove sapling planting caves are dug at the selected positions; the mangrove saplings are planted into the planting caves, three layers of maintaining sand bags are accumulated in sequence, and the caves are covered with silt or gravel or other sand grains to be tamped, wherein the first layer of maintaining sand bag is an organic fertilizer-gravel sand bag, the second layer of maintaining sand bag is a fresh oyster shell-sand-soil sand bag, and the third layer of maintaining sand bag is a gravel sand bag or a silt sand bag or a bag of other sand grains; the mangrove saplings are planted according to the method to form the mangrove forest in the area; the mangrove saplings are fixed through the fixing device; guard piles are arranged at the offshore end 2-5 meter away from the front end of the low water line. According to the method, the mangrove forest can be planted in intertidal zones with different bottom materials, the purpose of preventing stormy waves is achieved, and the mangrove forest survival rate is high.

Description

technical field [0001] The invention belongs to the technical field of mangrove planting, and in particular relates to a method and a fixing device for planting mangrove on the windward surface of the coastal intertidal zone. Background technique [0002] Mangroves are unique plant communities on saline-alkali tidal flats in bays and estuaries at the junction of tropical and subtropical land and sea. They are an important type of vegetation to maintain the ecological balance of the coast. "Guardian of the Coast". However, land reclamation, reclamation and cultivation, and sewage discharge have destroyed a large number of mangroves, resulting in a sharp shrinkage of the area. These areas often suffer heavy losses in typhoons and tsunamis. In Guangdong, Guangxi and other coastal areas, reinforced concrete embankments are mostly developed in coastal areas, and stones are piled up in the intertidal zone to dissipate waves. However, the amount of such projects is huge and confli...
