本文献综述是关于从褐煤制取合成腐植酸类物质的发展研究。褐煤腐植酸对土壤肥力、土壤形成以及植物营养和作物生长都是非常有益的。从褐煤腐植酸制备的各种金属腐植酸盐对植物的新陈代谢起很重要的作用。这些物质就是大家熟知的褐煤腐植酸——腐植酸类肥料。
This literature review is about the development of synthetic humic acids from lignite. Brown coal humic acid is very beneficial to soil fertility, soil formation and plant nutrition and crop growth. Various metal humic acids prepared from brown coal humic acid play an important role in plant metabolism. These are the lignite humic acid-humic acid fertilizers that we all know.
