盐沼草--白骨壤混种减轻污损动物危害的生物防治效果研究
Effect study on a biological prevention method applying mix-culturing of saltmarsh and Avicennia marina mangrove trees to reduce marine fouling fauna damage
摘要
Abstract
In Beilun estuarine area of Guangxi,China,the intertidal flat were filled to an elevation of about 220 cm Yellow Sea Datum to mix-culture Avicennia marina (AM)seedlings with four species of saltmarsh,aimed at stud-ying the effect of biological prevention method for reducing the fouling damage on mangrove trees.The results showed that Cyperus malaccensis (CM)and Zoysia matrella (ZM)were able to grow and spread faster,and more ef-ficient to slow down water velocity and accelerate sedimentation than Scirpus validus var.laeviglumis (SV)and Phragmites australis (PA).19 species of fouling fauna were found on saltmarsh and mangroves,among which Bala-nus littoralis ,Euraphia withersi ,Littorina melanostoma and L .scabra were major dominant species.Among four saltmarsh species,the fouled degrees on CM and ZM were significantly less than those on other two species.And the fouled degrees on four saltmarsh species were all significantly less than that on A .marina tree.The mix-culturing of saltmarsh CM or ZM with mangrove tree AM could efficiently reduce the fouling damage,resulting in better tree growth indexes i.e.tree height,leaf number,branch number,branch conservation and survival rate than those in mono-species treatment areas.In general,a saltmarsh-mangrove cooperating ecological conservation system could be a practical model for mangrove afforestation.关键词
