国内市售腐植酸产品包括作为生长调节剂的“抗旱剂1号。”和“旱地龙”,都有一个抗硬水性不佳的缺点。例如,北京自来水仅为中等硬度,“抗旱剂1号”浓度低于千分之一时几乎迅速全部絮凝,实用时要加大浓度;旱地龙的抗硬水稍好,但在十分钟内也大部絮凝。这些形成絮凝的腐植酸失去应有的功效,还给实际使用带来不便。本刊上两期连续介绍过的前苏联科学院通
Domestic marketed humic acid products include “Drought Resistant Agent No. 1” as growth regulators and “Dryland Dragons,” all of which have the disadvantage of being resistant to poor hard water properties. For example, Beijing tap water is only medium hardness, “Drought resistant agent No. 1” almost all flocculation almost immediately when the concentration is less than one per thousand, to increase the concentration when practical; dryland dragon hard water slightly better, but within ten minutes Department of flocculation. These flocculated humic acids lose their proper function, but also bring inconvenience to the actual use. This issue of two successive Soviet Academy of Sciences introduced
