以国内外土壤改良剂的研究与应用为基础,比较分析了3种高温好氧发酵工艺,提出了一种新型土壤改良剂生产工艺,即利用工业化好氧发酵工艺,将风化煤、草炭和畜禽粪便等有机废弃物转化为腐植酸有机肥,分别以加入磷石膏和保水剂作为添加剂,生产出适用于盐碱土和沙化土的土壤改良剂。 Based on the research and application of soil amendment at home and abroad, three kinds of high temperature aerobic fermentation process were compared and analyzed. A new production process of soil conditioner was put forward, that is, the industrialized aerobic fermentation process was adopted to mix the weathered coal, peat and livestock Poultry manure and other organic wastes into humic acid organic fertilizer, respectively, by adding phosphogypsum and water retaining agent as an additive to produce suitable for saline soil and sandy soil soil improver.
