近日,由中科院山西煤化所、江苏省通州市农业局、通州市专业肥料公司共同研究开发和推广示范的年产2.5万吨长效—缓释氮肥—腐植酸包裹尿素(UHA)全自动全封闭生产线,在江苏省通州市建成投产,标志着我国在尿素长效化技术方面的研究开发和推广示范取得重大进展。腐植酸包裹尿素是一种适合我国国情的多功能性生态氮肥,它利用先进的UHA 制备工艺,把廉价的天然风化煤腐植酸经过活化后混入少量粘结剂和微量元素,再将其包裹在尿素颗粒上,通过腐植酸的包被作用,与尿素发生部分络合反应,使 UHA 不仅发挥了腐植酸本身增进肥效、促进抗逆、改良土壤、抑制土壤脲酶和消化菌活性的化学—生物
Recently, an annual output of 25,000 tons of long-acting - slow-release nitrogen fertilizer - humic acid wrapped Urea (UHA) fully automatic closed by the Chinese Academy of Sciences Shanxi Coalification Institute, Tongzhou City, Jiangsu Province Bureau of Agriculture, Tongzhou professional fertilizer company jointly research and development and promotion of demonstration Production line in Tongzhou City, Jiangsu Province completed and put into production, marking China’s long-term urea technology research and development and promote the model made significant progress. Humic acid encapsulated urea is a multi-functional ecological nitrogen fertilizer suitable for China’s national conditions. It utilizes advanced UHA preparation technology, and activates low-cost natural weathered humic acid mixed with a small amount of binders and trace elements, and then wraps it in Urea particles, through the role of humic acid coating, and urea partial complexation reaction, the UHA not only played a humic acid itself to improve fertilizer efficiency, promote resistance, improve the soil, inhibit the activity of soil urease and digestive bacteria chemical - biological
