摘要:
为探索不同保护性耕作方式对土壤呼吸及根呼吸的影响,对比研究免耕秸秆还田(NTSR)、旋耕秸秆还田(RTSR)、深翻耕秸秆还田(PTSR)、免耕秸秆不还田(NTNSR)、旋耕秸秆不还田(RTNSR)和深翻耕秸秆不还田(PTNSR)等6种处理方式下玉米田土壤呼吸及根呼吸的动态变化特征及其与土壤水热因子的关系。结果表明,在整个测定期间平均土壤呼吸速率表现为PTSR>PTNSR>RTSR>RTNSR >NTSR>NTNSR;土壤水分含量与土壤呼吸速率的相关性表现为PT>RT>NT;土壤温度与土壤呼吸速率的相关性表现为NT>RT>PT;根系呼吸速率呈现出单峰曲线的变化趋势,最大值出现在玉米灌浆中期,最小值出现在玉米苗期。
