摘要:

于1994年6月至1995年4月在广西北界潮滩上进行红树植物红海榄人工苗造林试验.结果表明种植在滩面较高的盐地鼠尾黍盐沼草植物群落上的幼苗生长良好,成活率达92%,枝数和叶数保持较好;该地造林的主要胁迫因子是藤壶害。通过实验,提出了在胁迫条件下的一些造林对策.

Abstract:

The artificial seedlings of red mangrove Rhizophora stylosa were planted on a bare tidal flat of Beijie, Guangxi,from June 1994 to April 1995. It was indicated that the seedlings were better grown on the salt grass zone covered by Sporobolus virginicus where the ground level is higher than other zones.The survival rate of the seedlings reached 92% with higher preservation of branches and leaves. At the study site,the seedlings were mainly damaged by barnacle.Based on the afforestation experiment,some countermeasures were suggested to improve mangrove afforestation under stress conditions.
