泥炭又称草炭、泥煤和黑泥。它是植物有机残体长期累积,在水分过多的情况下,由于通气困难,有机残体经嫌气性微生物长期缓慢分解缩聚而形成的。从外观上看,泥炭是一种具有不同色调的较为疏松的棕黄色到褐黑色的物质,呈纤维状。在自然状态下,泥炭的湿度是很高的。泥炭干物质是由三种物质组成的,未完全分解的植物残体;植物组织分解后,丧失了细胞结构的黑色的无定形物质——腐植质;矿物物质。根据我们对青浦三海桥泥炭取样分析:腐植酸30～35％左右(干基);灰分38％(于基);溶于苯中的沥青质3％(干基),半纤维素等32％;水分80％左右。泥炭有机质的组成成分有腐植酸,沥青(包括蜡和树脂),纤维
Peat, also known as peat, peat and black mud. It is a long-term accumulation of organic residues in plants, in the case of excessive water, due to ventilation difficulties, organic residues formed by the long-term decomposition of anaerobic microorganisms polycondensation. From the appearance point of view, peat is a different color with a more loose brown to brown black substance, was fibrous. In its natural state, the humidity of peat is high. Peat dry matter is composed of three substances, incomplete decomposition of plant residues; decomposition of plant tissue, loss of cellular structure of the black amorphous material - humus; mineral matter. According to our sample analysis of peat in Sanhai Bridge in Qingpu: humic acid is about 30-35% (dry basis); ash is 38% (in base); asphaltene is dissolved in benzene 3% (dry basis), hemicellulose, etc. %; Moisture about 80%. Organic components of peat humic acid, asphalt (including wax and resin), fiber
