海南东寨港几种国外红树植物引种初报

Preliminary Report on Introduction of Several Alien Mangrove Plants in Dongzhai Harbour of Hainan Provbince

为我国华南沿海防浪护岸林体系工程建设试验性引进优质红树植物资源,旨在提高防护林体系的建设工程质量和增强生物工程体系的抗灾、减灾能力.从生物生态学特性、生长适应性、树高、地径的生长量以及开花结实情况,初步分析了海南岛东寨港从澳大利亚和墨西哥引进的几种红树植物的生长表现.结果表明:拉关木、直立柱果木和阿吉木在该地区可开花结果,其中拉关木生长表现最优,为一种耐高盐度的速生树种;根据寒害调查情况,拉关木和澳洲白骨壤有较耐寒的生长特性,具北移栽培的潜力.

The growing performance of several mangrove species that were introduced from Mexico and Australia was preliminarily analyzed based on their bio-ecology, adaptability, increment of height and basic diameter, flowering and fruiting. The results reveal that plants of Laguncularia racemosa, Conocarpus erectus and Aegialitis annulata have flowered and fruited in Dongzhai Harbour, among which C. erectus grew very well and was a high salinity-tolerance and fast growing species. According to a cold＇ damage investigation, C. erectus and Avicennia marina var. australasica have a strong cold-tolerance ; therefore they have the potential to be planted northward in the future.
