| 摘 要： | 对干湿交替条件下土壤氮素的矿化、损失以及对土壤团聚体结构和土壤胀缩性、土壤微生物活性和群落等的影响进行了综合评述。研究表明,干湿交替能够对土壤氮素的矿化和损失产生影响,并且干湿交替条件下土壤中氮素的转化与土壤团聚体结构、土壤胀缩性以及土壤微生物活性和群落密切相关。此外,针对目前研究中的不足,提出了今后的研究方向,认为开展干湿交替条件下土壤氮素转化与物理性质和微生物的关系,尤其是肥料氮素的微生物转化过程,为进一步开展干湿交替条件下氮素在土壤中的转化过程,明确自然条件下土壤氮素转化机制的相关研究提供参考。

| Abstract: | This paper summarized the research progress in the effects of drying/wetting cycles on the mineralization,transformation,and losses of soil nitrogen,and on the soil aggregate structure,swelling-shrinking characteristics,microbial activity,and microbial community.It was indicated that soil drying/wetting cycles could affect the mineralization and losses of soil nitrogen,and the transformation of soil nitrogen was closely related to the soil aggregate structure,swelling-shrinking characteristics,microbial act... |
