| 摘 要： | 采用离体根法于2007年5-10月测定了长白山阔叶红松林组成树种水曲柳4个龄级林木的根系呼吸,监测了林内空气温度、不同深度土壤温度、土壤含水量及根系氮含量,初步研究了水曲柳天然林根系呼吸季节变化及其影响因素.结果表明:4个龄级的根系呼吸速率均具有明显的季节动态,其中7月份最高,10月份最低,呈单峰曲线,生长季节的不同月...

| Abstract: | To study the seasonal variation of root respiration of Fraxinus mandushurica and its controls in broadleaf-Korean pine mixed forest of Changbai mountains,monthly root respiration rate was measured using in vitro root method from May to October 2007,and air temperature,soil temperature,soil moisture and root N content were determined simultaneously.The results showed that the root respiration rate of four age classes had an obvious seasonal variation,with the maximum occurring in July and the minimum in Octo... |
