| 摘 要： | 1997年5～9月于山东海阳市黄海集团公司养虾场,用5个实验围隔研究了对虾综合养殖生态系底泥细菌的数量动态.结果表明,底泥细菌数量波动在4.10×108～12.36×108cells·g-1之间,平均为8.09×108±2.17×108cells·g-1.随着养殖时间的推移,底泥细菌数量逐渐增加.底泥细菌数量最大值出现在表层1cm之内,2～3cm以下泥层,细菌数量明显减小

| Abstract: | The numerical dynamics of sediment bacteria was studied from May to September 1997, in the Shrimp Farm of Huanghai Fisheries Group Corporation with five experimental enclosures. It shows that the numbers of sediment bacteria ranged from 4.10 x 10(8) to 12.36 x 10(8) cells.g-1, averaged 8.09 x 10(8) +/- 2.17 x 10(8) cells.g-1, and increased gradually with increasing cultural time. The maximum was in 0-1 cm layer, and decreased obviously bellow 2-3 cm layer. |
