NO-3-N
1.
Before and after each irrigation, NO~-_3-N concentration in 0~200 cm soil and 135 cm deep leachate of maize/barley intercropping was determined in Hexi corridor of Gansu Province, with three rates of nitrogen application(0, 150, 300 kg/hm~2), two rates of irrigation level (816, 1632 m~3/hm~2).
以甘肃省河西走廊灌区为试验地点,分别在0、150、300kg/hm2氮水平和816、1632m3/hm2灌水量下,对3次灌水前、后大麦/玉米带田0～200cm土壤NO-3-N含量变化和灌水后135cm处渗漏液NO-3-N浓度进行了测定。

The trends of content of NO~-_3-N was.
不同生长年限苜蓿地土壤NO-3-N的含量变化趋势相同,2m以内土层生长年限越短,NO-3-N含量越少,2m以下变化趋势相反。
