摘要: 从13个省、自治区的滩涂湿地中采集了土壤和水样品共计837份,从中分离出了827株木霉菌株。实验结果表明,土壤样品比水样更容易分离到木霉菌,且土壤样品中的含盐量越低越容易分离到木霉菌。海拔高度也是影响木霉分布的因素,海拔高度在100 ~ 1 200 m之间木霉的分离率最高,这可能与该海拔区间中的植被相对丰富有关。

Abstract: We collected 837 soil and water samples from the coastal beaches and wetlands ofthirteen provincesand autonomous regions, 827 Trichoderma stains among which were isolated. Experimental results show that Trichoderma is more easily isolated from soil samples than from water samples. Moreover, lower salt content in soil samples is more easy for Trichoderma isolation.Altitude is another vital factor influencing Trichoderma distribution.Isolation rate of Trichodermais the highest when its altitude ranges from 100 m to 1 200 m. This may attribute to the rich vegetation at such altitudes.

Key words: coastal beach and wetland, isolation rate, Trichoderma, soil sample, water sample
