腐植酸尿素在农业生产和面源污染防控中的研究与应用

Application and research progress of humic acid urea in agricultural production and non-point source pollution prevention and control

近年来,随着《到2020年化肥使用量零增长行动方案》的发布与实施,减肥增效已成为我国农业绿色高质量发展的一个重要途径。腐植酸尿素因其在减肥增效方面独特的优势,为我国农业转型升级注入新的活力,尽管如此,腐植酸尿素的生产工艺及其在农业生产和面源污染防控方面的应用推广仍存在许多问题。在农业减肥增效与绿色发展的大背景下,文中系统综述了腐植酸的活化方法、腐植酸与尿素的作用机理、腐植酸尿素的生产工艺、田间应用效果及在面源污染防控中的研究进展,提出了目前腐植酸尿素生产中存在的问题和下一步研究重点及应用推广建议,为化肥使用零增长行动方案和农业面源污染防控提供参考。

In recent years,with the release and implementation of the“Zero Fertilizer Use Zero Growth Action Plan by 2020”,fertilizer reducing and efficiency increasing have become an important way to develop green and high quality agriculture in China.Humic acid urea has been used as a new element for agricultural transformation and upgrading due to its unique advantages.However,there are still many problems to be solved in the production of humic acid urea and its application and promotion in agricultural production and non-point source pollution prevention and control.Under the policy background of agriculture with fertilizer reducing and efficiency increasing for green development,this paper systematically reviewed the research progress of the activation methods of humic acid,the mechanism of action of humic acid and urea,the processing technology,field application effects and the prevention and control of non-point source pollution of humic acid urea,proposed the problems existing in the production of humic acid urea and recommendations for new product development focus and application promotion,which will provide reference for the use of zero-growth action plan for chemical fertilizers and agricultural non-point source pollution prevention and control.
