水溶肥与灌溉设施相结合,通过灌溉施肥,实现水、肥资源的科学精确利用。中国农业大学资源与环境学院教授陈清介绍说,根据肥料登记标准,水溶性肥料是指可以完全溶于水的多元复合肥料,能迅速地溶解于水中,无残渣。据介绍,根据灌溉施肥要求,水溶肥包括传统上的大量元素单质水溶肥(如尿素、氯化钾等)、水溶性复合肥料(一铵、二铵、硝酸钾、磷酸二氢钾等)、农
Water soluble fertilizers and irrigation facilities combined by fertigation, to achieve scientific and precise use of water and fertilizer resources. According to Chen Qing, a professor at the College of Resources and Environment at China Agricultural University, water-soluble fertilizers refer to multiple compound fertilizers that dissolve completely in water, dissolve quickly in water without residue, according to the standard for fertilizer registration. According to reports, according to the requirements of irrigation and fertilization, water-soluble fertilizer, including the traditional elements of a large number of single-element water-soluble fertilizer (such as urea, potassium chloride), water-soluble compound fertilizers (monoammonium, diammonium, potassium nitrate, potassium dihydrogen phosphate, Farmers
