Microbial Study of Mangrove Soil at Dongzhai Harbor in Hainan

Abstract

Abstract: Three groups of microbial amount of mangrove soil at Dongzhai harbor in Hainan were studied.The results show as follows:①Mean amount of soil bacteria in Kandelia candel forest and Bruguiera sexangula forest is 4 87×10⁷ and 7 55×10⁷〔ind·(g.dry soil)^-1〕 respectively,which is higher than that of controlled mudflat without mangrove forest〔1 22×10⁷ind·(g.dry soil)^-1〕;②The amount of bacteria at layer of 10-20cm is the most in three layers of 0-10、10-20 and 20-30cm;③Mean amount of soil bacteria in Bruguiera sexangula forest is higher than that in Kandelia candel forest;④The amount of bacteria is related to the amount and distribution of plant residue and litter;⑤Filamentous fungi and actinomyces are not found out by normal isolation methods,which is perhaps related to least amount and special habitat of local mangrove soil.

Key words: litter decomposition, abiotic factor, biotic factor, semi-arid and arid region.
