Abstract:

Rice is an important cereal crop in China. The loss of nitrogen and phosphorus and their agricultural non-point source pollution are attracting wide attention. Based on the high yield and environmental benefit, starting from the features of nitrogen and phosphorus loss in paddy field, this paper reviewed the effects of fertilizer amount, organic fertilizer, slow/controlled release fertilizer and different fertilization time and location on nitrogen and phosphorus loss in paddy field. The authors put forward the measures to control the nitrogen and phosphorus loss in paddy field, including improving fertilization model, promoting the research and development of new environmental protection fertilizers, applying the ecological interception technology. 

Key words: rice, nitrogen, phosphorus, fertilization, loss

摘要:

水稻是我国主要的粮食作物,稻田氮磷养分流失及其带来的农业面源污染等环境问题引起广泛关注。本文从稻田氮磷流失的特征出发,从粮食高产和环境效益的角度,对施肥量、有机肥、缓控释肥及不同施肥时间、施肥位置等施肥方式对稻田氮磷流失的影响进行综述,提出改善施肥模式,促进新型环保肥料的研发推广以及应用生态拦截技术等途径实现稻田氮磷流失的防治。
