1硅胶管气样原位采集技术研究土壤N_2O浓度及通量变化显示文摘箱法被广泛用于监测土壤N2O排放通量,但在原位采集高浓度土壤N2O、全天候监测N2O通量变化、动态研究土壤剖面N2O的行为等方面存在弊端。本研究通过室内模拟硅胶管对N2O的通透性,探索硅胶管用于原位采集土壤气样的理论可行性。田间试验设施用铵态氮肥(NH4+)、施用硝态氮肥(NO3-)及施用硝态氮肥加葡萄糖(NO3-+C)等3个处理,同时安置硅胶管和采样箱,验证硅胶管法在原位采集高浓度土壤N2O气样、监测土壤N2O浓度以及排放通量的实际效果,并与箱法进行比较。结果表明,硅胶管内外的N2O气体经2.9 h达到95%的平衡,完全能满足大田采样要求;用硅胶管法原位采集高浓度土壤N2O气样的效果显著优于箱法采样。其浓度变化表现出明显的时间规律,浓度梯度法计算的N2O排放通量与箱法测定结果呈显著正相关,但数值偏低;偏低的程度取决于采样位置和土壤中N2O产生位置的匹配程度。建议采用埋于土壤表层的硅胶管计算地面N2O排放通量,或在不同土层埋入硅胶管研究土壤剖面N2O行为的时空变异。陆星 巨晓棠 张福锁 Volker Romheld 2010植物营养与肥料学报2010,16,2:6
