摘要
在行业转型升级和磷资源贫化的背景下,传统64％DAP原料酸严重短缺.为充分利用有限磷资源,以渣酸、萃余酸、浓磷酸为原料,开发含中量元素硫的功能型磷酸一铵新产品,实现传统磷酸一铵的提质增效,提高作物对磷养分的吸收利用率,达到节肥增效的目的.
Abstract
Under the background of industry transformation and upgrading and phosphorus resources,the traditional 64％dap raw acid shortage,to make full use of limited phosphorus resources,with slag acid,residual acid,concentrated phosphoric acid as raw material,the development of medium element sulfur functional ammonium phosphate new products,realize the traditional ammonium phosphate mass efficiency,improve the utilization of crop phosphorus nutrient absorption,achieve the purpose of section fertilizer efficiency.
