The invention discloses a method for building near-natural
vegetation on a tropical
coral reef. According to the invention, six indigenous plants (including three types of
shrub, grass and
vine, and
nitrogen-fixing leguminous plants) like Scaevola sericea, Canavalia maritima,
Ipomoea pes-caprae,
Vitex trifolia Linn var simplicifolia Clam, Phyla nodiflora and Spinifex littoreus applicable to being planted in the tropical
coral reef are selected according to harsh environmental conditions of
coral reefs and on the basis of preliminary investigation and research on
vegetation and soil in
South China Sea Islands; meanwhile, referring to plantation of natural coastal plants in Paracel Islands, and through the
optimal combination of a series of processes of digging planting holes, placing farmyard base
manure and coconut
bran, applying a water-retaining agent, soaking bagged seedlings in water, applying a compound
fertilizer, applying a little amount of
iron sulfide or iron-aluminum oxides (adjusting a pH value), adding dry duckweed (increasing a C source), backfilling sand or foreign soil, performing maintenance, etc., the
survival rate of the plants reaches 90% or above after about 2 months; thus, green plants can be basically covered; near-natural
vegetation is formed; certain functions of preventing wind and fixing sand are exerted; meanwhile, maintenance is relatively simple.
