Factors affecting the number of soil microbes in the coastal terrace
摘要
Abstract
Using data collected from certain locations,the quantity of soil microorganisms at three typical forests (Palm forest,Acacia auriculiformis and Horsetail beefwood) in the coastal terrace of Wenchang,Hainan and its relationship with the soil factors were studied.The results showed as follows:the quantity of soil microorganisms was significantly different in different forests.The population of bacteria in the palm forest was the biggest (3 144.67×104cfu·g-1),followed by the Acacia auriculiformis forest (1 817.97×104 cfu·g-1) and the Horsetail beefwood forest (1 503.67× 104 c fu·g1).The number of fungi was the biggest in the Acacia auriculiformis (46.12× 104 cfu·g-1) and the smallest in the palm forest (17.70× 104 cfu·g-1).The amount of actinomycetes was the biggest in the palm forest (413.84×104 cfu·g-1) and the smallest in the Acacia auriculiformis forest (123.30×104 cfu·g-1).The soil microorganism number of three major groups was as follows:bacteria＞ actinomycetes＞ fungi.Except for the quantity of fungi in palm forest,the number of soil microbes decreased with an increase of the soil depth.The relationship between soil microbial number and soil nutrients in three forests in coastal terrace was observed.关键词
