含腐植酸的原料腐植酸是一种天然的有机高分子化合物。它广泛存在于土壤、泥煤、柴煤和褐煤中。泥煤泥煤又叫泥炭或草炭。在沼泽化地区水分过多的情况下,地表通气困难,植物有机残体以嫌气性微生物分解为主,但进行得十分缓慢,不能全部分解,经过长期积累形成了泥煤。它是在其干燥物中含矿物质不高于50％的有机质堆积层。有的直接裸露地表,有的埋藏于不同厚度的泥沙层下面。在新鲜状态时,湿度可达85—95％,大多呈棕色至褐色,经风化后颜色变暗,呈暗
Humic acid containing raw materials Humic acid is a natural organic polymer compounds. It is widespread in soils, peat, coal and lignite. Peat Peat is also called peat or peat. In the case of too much moisture in the swampy area, surface aeration is difficult. The organic residues of plants are mainly decomposed by anaerobic microorganisms, but they are carried out very slowly and can not be completely decomposed. After long-term accumulation, peat is formed. It is a layer of organic matter that contains no more than 50% of minerals in its dried material. Some directly exposed surface, and some buried in different thickness of the sediment below. In the fresh state, the humidity up to 85-95%, mostly brown to brown, after weathered the color darken, dark
