选用熔融尿液为载体,以石蜡及阴离子表面活性剂烷基苯磺酸盐和阳离子表面活性剂烷基胺盐等混合物为复混肥料防结块剂,添加对尿素水解有抑制作用的尿酶抑制剂氢醌和对土壤中铵离子氧化有抑制作用的硝化抑制剂双氰胺混合物,经特制喷涂设备喷涂包衣生产具有养分缓释、防结块性能好的高氮型、高浓度复混肥料[以总养分45%的30 6 9复混肥料为例,w(N)可达30%]。使用熔融尿液替代机械油为复混肥料防结块剂载体,解决了因使用机械油造成的二次污染;通过氮素缓释剂的使用,氮素利用率提高13%。
Selection of molten urine as a carrier to paraffin and anionic surfactants alkyl benzene sulfonate and cationic surfactant alkylamine salt mixture as a compound fertilizer anti-caking agent, adding urea hydrolysis inhibition of urease Inhibitors of hydroquinone and nitrification inhibitor of ammonium ion in the soil oxidation inhibitors dicyandiamide mixture, spray coating by a special spray equipment to produce a nutrient-slow release, anti-caking performance of a good high-nitrogen, high concentration complex Fertilizers [30% (30%) of compound fertilizer with total nutrients of 45%, w (N) up to 30%]. The use of molten urine instead of mechanical oil as a compound fertilizer anti-caking agent carrier, to solve the secondary pollution caused by the use of mechanical oil; through the use of nitrogen sustained-release agent, nitrogen utilization increased by 13%.
