摘要
煤炭腐植酸与土壤腐植酸在结构、功能和性质上基本相同,可成为补充土壤腐植酸的重要来源。我国用于生产腐植酸肥料的泥炭、褐煤和风化煤资源丰富,从中可分离出黄腐酸、棕腐酸、黑腐酸等腐植酸类物质。大量的科学试验充分证明:腐植酸类物质是化肥提质增效最好的绿色伴侣;可以使各种营养元素以络合态等形式结合,并逐渐释放,起到缓释氮素、活化磷素、调控钾素的作用,既提高了化肥的利用率,还能起到改良土壤和改善农产品品质的作用。近几年来,国家提出化肥减量增效的目标和政策倡导,促进了腐植酸类肥料的快速发展。为了适应现代农业需要,推动腐植酸肥料产业健康有序发展,需要加强研究3个问题:(1)要深入研究腐植酸肥料对植物生长作用的机理;(2)要加强腐植酸肥料的应用基础研究;(3)要加快腐植酸肥料标准的制修订。
Coal humic acid and soil humic acids are basically the same in structure,function and property,that be an important source of soil humic acid.In China,peat,lignite and weathered coal are rich in humic acid,in which fulvic acid,brown humic acid and black humic acid are separated.Proof from large number of scientific experiments proved that humic substance is the best green partner for improving the quality and efficiency of nitrogen,phosphorus and potassium fertilizers.The combination of humic acid and chemical fertilizers can gradually release nitrogen,phosphorus,potassium and other nutrients in the form of complexation,that have the founction of slow-release nitrogen,activating phosphorus and regulating potassium.It improves the utilization rate of fertilizer,soil quality and agriculture product quality.In recent years,the state has put forward the goal and policy advocacy of reducing production and increasing efficiency of chemical fertilizer promoted the rapid development of humic acid fertilizer.There three issues should be concerned for the needs of modern agriculture and developing the humic acid fertilizer industry healthily and steadily.The first,mechanism of humic acid fertilizer on plant growth should be deeply researched.Secondly,the basic research of humic acid fertilizer should be strengthen.Thirdly,formulation and revision of humic acid fertilizer standards should be accelerated.
