Method for planting mixed mangrove forest in groups

Abstract

The invention discloses a method for planting a mixed mangrove forest in groups. According to the method, local mangrove species are planted with row as unit; the direction of the row is parallel to the coastline; one local mangrove species is planted in each row; kandelia candel hypocotyls are inserted between the rows; the local mangrove species comprise Bruguiera gymnorrhiza, kandelia candel, Rhizophora stylosa, avicennia marina and Tung blossoms; and the mangrove species are 2-3 years old and the mangrove species in one row closest to the seat are 3 years old. The method is beneficial for bringing colony heterosis and boundary advantages of each mangrove species into full play, and has the advantages that topographies and spaces are sufficiently utilized and forest tree growth is promoted. The method has the advantages as follows: as more mature mangroves are planted in near-sea sections, the method is beneficial for protecting the kandelia candel hypocotyls and plants in the back rows and reducing impacts of tides on the mixed forest, the surrival rate of afforestation can be increased, the use of building materials is reduced, the secondary pollution is avoided and the cost is reduced.

Description

technical field [0001] The invention relates to a method for mass planting mangrove mixed forests, which is especially suitable for use on tidal flats whose elevation has been artificially raised. Background technique [0002] Mangroves are trees, shrubs, palm-like or terrestrial fern communities that grow in the intertidal zone of tropical and subtropical coasts and are submerged by tidal cycles. In addition to directly providing forest products, it also has ecological functions such as catching sand, promoting siltation, preventing waves and revetment, filtering land runoff and organic matter and pollutants brought out inland, purifying air and sea water, reducing marine pollution, and reducing red tide disasters. Provide habitat and feeding grounds for fish, shrimp, crab, shellfish and birds. Referring to the global ecosystem service function classification method, mangrove wetlands have four major functions: supply, regulation, support and culture. [0003] Worldwide, ...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the defect of poor ecological stability of the existing artificial mangroves composed of a single tree species, the object of the present invention is to provide a method for planting mangrove mixed forests in groups, which realizes the standardization of mangrove planting on artificially improved tidal flats , large-scale, improve the survival rate and growth rate of mangroves, contribute to the ecological restoration of coastal wetlands, and achieve good economic and ecological benefits
