环境和土壤中硝态氮的研究──以阜康荒漠生态站地区为例
Studies on the NO3--N in the Environment and Soil
【摘要】 本文较系统的研究了干旱区氛素循环中硝态氮的来源和去向。研究表明由降水带入的N最少约为6kg/ha,地下水中硝态氮均低于1ppm,土壤剖面深处硝态氮可随水分上移供根区利用。
【Abstract】 This paper systematically studied the origin and direction of NO3-N in thenitrogen element circulation in arid area. The result shows that the nitrogen from rainfall is 6kg/ha at least, it’s all less than l ppm in the underground water. The NO3 - N in the soilsection can be utilized to the roots with the moisture lifting.
