NO3-N,NO~-_3-N
NO-3-NNO3-N
1.Five years average concentrations of NO-3-N,NH+4-N,and Total Inorganic Nitrogen(TIN) in wet depositions in Huizhou City are 0.结果表明,近5年惠州市湿沉降平均NO3--N含量为0。
2.Effects of combining application of nitrogenous,phosphorus and potassium fertilizers on the cumulation of NH+4-N and NO-3-N in soil profile,the yield and quality of flue-cured tobacco were studied according to the field experiment.通过大田试验研究了不同氮磷钾配施对NH4+-N和NO3--N在植烟土壤中累积及烤烟产量品质的影响。
3.Among the DN concentration of NH+4-N was lower than that of NO-3-N in general,and the former.结果表明:稻田氮素径流损失的主要形态是溶解态氮(DN),DN中的NH4+-N浓度基本低于NO3--N浓度,NH4+-N浓度受施氮水平的影响,而NO3--N浓度不受施氮水平的影响。
3)Nitrate[英]['na?tre?t][美]['na?tret]NO3-N
1.The effects of ammonia,nitrate and pH on the growth of Salvinia natans L.)为研究对象,在Hoagland培养液的基础上模拟生活污水中NH4+-N和NO3--N的浓度以及pH,研究了培养条件对槐叶萍生长的影响。
4)nitric nitrogenNO3-N
1.The effects of different cropping systems on content of nitric nitrogen in soils and vegetable were studied.研究了不同种植制度对农田土壤和蔬菜NO3--N含量的影响。
5)NO_3~-NNO3-N
1.NO_3~--N deep migration in loess layer of non-saturated zone under irrigation condition;通过渭北黄土塬地区NO3--N的原位运移试验,测定了10 m范围内黄土超根层中NO3--N浓度随时间的变化,对NO3--N和土壤含水量的运移通量及运移速率进行了定量分析。
2.Effect of Long-term Covering with Plastic Film on NH_4~+-N and NO_3~--N in Depth Profile of Brown Earth;棕壤长期定位试验结果表明,覆膜使表层土壤中NH4+-N含量明显增加,并使各个层次NO3--N含量都有所增加,有效地减少了NO3--N的淋失。
3.Effect of Coated Urea on NO_3~--N and NH_4~+-N in Soil Exduation;采用盆栽试验方法,研究尿素涂层后施用于水田土壤其渗出液NO3--N和NH4+-N含量的变化情况。
