摘要:
 在2010年3月至2010年6月,利用Li-8100土壤呼吸自动观测系统,研究了位于河南省济源市的华北低山丘陵区石榴-小麦间作系统(间作系统)和小麦单作系统(单作系统)内土壤呼吸速率(SRR)的时间变化特征及其与土壤温度和湿度的关系。结果表明:(1)间作系统和单作系统的SRR在晴天-多云均表现出明显的时间变化特征,呈单峰变化趋势,在阴天日波动变化幅度较小。SRR在晴天-多云和阴天与土壤温度的变化趋势均基本一致。间作系统的SRR高于单作系统。整个观测时期内间作系统和单作系统的平均SRR分别为1.813 μmol·m-2·s-1和1.642 μmol·m-2·s-1。(2)间作系统和单作系统SRR与15 cm处土壤温度存在显著的指数相关关系,在该深处的Q10值分别为1.73和1.49。(3)间作系统和单作系统与20 cm处的土壤体积含水量与SRR的相关关系均不明显。
