swamp soil

基本解释

The three major soil types in this region are the paddy soil, the alluvial soil, and the salt swamp soil.
主要土壤有水稻土、冲积土和滨海盐渍沼泽土（海涂土壤）等三个土类。
As the vertebrate monsters have waxed and waned, the insects have gone on mating and hatching and, as they do, populating every swamp, tree, and patch of soil.
当脊椎动物们还处于盛衰无常的阶段时，昆虫们就已经统治了每一块沼泽，每一棵树木甚至每一块土地，它们在忙着交配，孵化出越来越多的后代。
The results indicated that there are salt-resistant, mesophilic and cryogenic actinomycetes in swamp and lakeside soil of the Qinghai Lake and in salinized wasteland soil nearby the Qinghai Lake.
结果表明：①湖泥、湖滨土壤及盐化荒地土壤中存在一定数量的中、低温耐盐放线菌。
