我国有丰富的泥炭以及含腐植酸的褐煤和风化煤资源,自从1974年试验推广腐植酸类肥料以来,这些资源已开始被人们所重视,泥炭和腐肥的施用效果也逐步为群众所认识。产量比较大的是以就地原料、就地加工和就地使用的腐植酸类堆肥。这种堆肥含速效氮1%左右,腐植酸20%左右,灰份大,水溶性差,但增产效果斤肥也有半斤左右,这个数字也是很可观的。工业化生产的品种由于对原料质量不够重视,加工不细,原料材料
Our country has abundant peat and lignite and weathered coal resources containing humic acid. Since the pilot promotion of humic acid fertilizer in 1974, these resources have begun to be valued by people, and peat and rot manure application effect is gradually recognized by the masses. The larger the output is humic acid compost based on local feedstock, on-site processing and on-site use. This compost contains about 1% available nitrogen, humic acid 20%, ash, water-soluble, but the yield increase of about half a catty fat, this figure is also very impressive. As the industrialized varieties of raw materials due to insufficient attention to quality, processing is not fine, raw materials
