The seasonal change of total nitrogen in native meadow has the same change with medial degenerative meadow,‘black-soil-batch’degraded grassland and 2 years-old grassland. All of them had the most total nitrogen in August except for 4 years-old and 6 years-old grassland.
全氮含量的季节性变化在未退化高寒草地、中度退化草地、“黑土滩”退化草地和人工2龄草地与全磷的变化趋势一致,均是8月份含量最高,只有人工4龄和6龄草地全氮含量在8月份最低,呈先降低后升高的规律变化。
