摘　　要：腐植酸钾是以泥炭、褐煤或风化煤等为原料的腐植酸结构中的酸性基团与氢氧化钾反应而生成的,主要包括干法工艺制成的腐植酸钾和湿法工艺制成的腐植酸钾,是一种新型钾肥来源。概要了两种腐植酸钾的生产工艺及其在新型肥料生产中的应用,干法工艺生产的腐植酸钾可广泛用于复合微生物肥、有机-无机复混肥等基肥生产,而湿法工艺生产的水溶性腐植酸钾是水溶性肥料中非常重要的一种钾素原料。腐植酸钾作为新型钾肥在改良土壤、刺激作物根系发育、防止钾素固定以及提高作物产量、改善作物品质等方面具有重要作用。Potassium humate is generated by the acidic groups of humic acid from peat, lignite or weathered coal reacted with potassium hydroxide. It mainly includes potassium humate made with dry process and wet process, and it is regarded as a new type of potash fertilizer. Two kinds of production process of potassium humate and the application as the main materials for new type fertilizers was summarized. Potassium humate with dry process that could be widely used in microbial compound fertilizer, organic-inorganic compound fertilizer etc., using as base fertilizer application. On the other hand, water soluble potassium humate with wet process was very important material of potassium in water soluble fertilizer. As the new type of potassium, potassium fertilizer humate has the functions of soil improvement, stimulating crop root development, avoiding potassium fixation and improving crop yield and quality.
