摘要
本文在调查、分析毛乌素沙地泥炭分布、储量及其理化性质的基础上，进行了栽培试验，并论证了在当地开发应用的广阔前景及经济效益。毛乌素沙地的丘间低地广泛分布有泥炭，埋深在５０～１５０ｃｍ，其储量约在３００万吨，具有重要的开采价值。泥炭的纤维含量在４２．２％～８６．７％，其发热量在１１４２～２３９７卡／ｋｇ。特别是泥炭具有重要的保水性质，可作为保水剂利用。以毛乌素沙地为例，施用泥炭后，１０多种供试植物在停灌６０～１００天的条件下，仍然可维特正常的生长。
s The article has done a cultivating test after investigation and an-alysis on the peat distributions,reserves,physical and chemical property in theMaowusu Sandy Land.It also proofed that the peat lias a good developinag andutilizing prospects and economic benefit in that areas.The peat entensively dis-tributed on the hilly lands in the Maowusu Sandy Land.It existed at 50～150cmunder the ground.Its reserves has about 3 million ton and it has very importantvalues to develop.Cellulose: 42.2%～86.7%,Generate Heat: 1142c/kg～2397c/kg.If has important absorbing water property and can be used as a absortant.Taking a example by the Maowusu Sandy Land,10 kinds of testing piants stillmanitained it regular growth under the condition to stop irrigating water for60～100 days after the peat used. But the contrast testing plants witherededto be death.
