1)  N loss by runoff
氮素径流流失
2)  nitrogen runoff loss
氮素径流损失
1.
Effect of controlled-release nitrogen fertilizer on reducing nitrogen runoff loss and increasing nitrogen recovery efficiency of rice plant;
施用控释氮肥对减少稻田氮素径流损失和提高水稻氮素利用率的影响
3)  soil nitrogen loss by erosion
土壤氮素径流流失
4)  N runoff
氮素径流
1.
However,owing to the no draining and the higher band,the paddy field under MRD had a notable reduction of drainage,resulting in a marked decrease of N runoff than that under MR.
结果表明:与MR处理相比,稻鸭共作系统稻田渗漏液氮素浓度尤其是NO3--N浓度显著减少,与CK处理相比,稻鸭共作稻田渗漏液氮素浓度有增加趋势;MRD处理在施肥7~9d后,田面水中的NH4+-N和NO3--N浓度高于MR处理,由于MRD处理不用搁田且田埂较高,田间排水量显著减少,氮素径流损失反而显著少于MR处理;与MR处理相比,MRD处理增加了鸭粪的氮素投入,减少了氮素渗漏和径流损失,减少了化学氮肥用量,增加了水稻地上部吸氮量;MRD系统的氮素输入总量和氮素输出总量均减少,且减少量基本相等。
5)  nitrogen loss
氮素流失
1.
Nitrogen loss in rice-wheat cropping farmland and its control measures;
稻麦轮作农田氮素流失及控制对策研究
2.
An experimental research on soil erosion and nitrogen loss under different vegetation cover;
不同植被对土壤侵蚀和氮素流失的影响
3.
Soil nitrogen loss processes resulted from rainfall and runoff were monitored in a small agricultural catchment of red soil areas in Jiangxi Province with the aim to investigate the relationship between the soil nitrogen loss and the corresponding rainfall and runoff.
以江西低丘红壤区农业小流域为研究对象,在自然降雨条件下对小流域内试验小区、上游灌渠和小流域出口径流中的氮素浓度进行监测,旨在从小区尺度和小流域尺度阐明农业小流域氮素流失与降雨和径流的关系。
6)  nitrogen losses
氮素流失
1.
On the basis of water-nitrogen coupling balance theory and field observation results,a simple but comprehensive model was developed to predict nitrogen losses from a urea applied rice paddy field,considering all the important hydrological pathways such as surface runoff,lateral seepage,and vertical leaching.
基于水氮耦合平衡理论和田间实际观测,开发了一套既简单又综合的水田氮素流失特征模拟模型。
