摘要
土壤氮矿化-固持周转(MIT)过程与土壤供氮力及氮素损失间存在密切关系。本文概述了近年来MIT过程的研究方法及其相应的模型;对土壤温度、土壤水分、土壤理化性质、植物生长状况以及有机、无机肥的施用等影响MIT过程的主要因素进行了较详尽地阐述,并展望了今后主要的研究方向。
The nitrogen mineralization - immobilization turnover(MIT) process in soil is closely connected with the capacity of nitrogen supply to plant and the loss of nitrogen to environment . The paper outlined the recent methods of MIT process and its models . The key effect factors , such as soil temperature , soil water , soil physical and chemical characters , growth state of plant and application of organic and inorganic fertilizers , were elaborated . The main study direction on the future reseach was alse discussed.
