摘    要:介绍了中国肥料利用率状况、所施肥料的去向及土壤中养分的积累与亏损。据估计,中国自1985~1996年,约有9900万吨N被淋失和逸散,6000万吨P2O5和1400万吨K2O固定于土壤中。如何提高肥料利用率是中国化学肥料工业紧迫的课题,针对不同类型化肥厂提出了生产控制释放肥料、腐植酸螯合尿素、稳定的碳酸氢铵、部分酸化磷矿复合肥料、完全水溶性复合肥料以及熔融钾镁肥的途径,以提高肥料利用率。

关 键 词:肥料利用率  控制释放肥料  土壤中营养的累积与亏损  尿素  碳酸氢铵  部分酸化磷矿

Abstract:The fertilizer use efficiency, the fate of applied fertilizer and the accumulation and deficit of nutrients in soil are introduced. It is estimated that about 99 million tons N is leached and is escaping into water or air, 60 million tons P\-2O\-5 and 14 million tons K\-2O are fixed in soil in 19851996 in China.How to raise fertilizer use efficiency is an urgent subject in Chinese fertilizer industry. Some products are suggested for various chemical fertilizer plants in this paper , such as controlled release fertilizer, chelated urea by humic acid, stabilized ammonium bicarbonate, partially acidulated phosphate rock compound fertilizer, fully water soluble compound fertilizer and fused magnesium potassium fertilizer.
Keywords:fertilizer  use efficiency  controlled release fertilizer  the accumulation and deficit of nutrients in soil  the fate of applied fertilizer  urea  ammonium bicarbonate  partially acidulated phosphate rock
