摘  要:
根系导水率研究在SPAC系统水分传输应用中有重要意义。通过对土壤水分、盐分、养分、温度、质地和寄生生物等多种土壤因素影响根系导水率研究现状的论述与分析,对相关研究进行了总结,认为今后在研究多种环境因素对根系导水率影响的同时,还应考虑时间(包括天、月、年等不同时间尺度)对根系导水率的影响;为推动根系导水率研究的发展,还需要对现有的测定手段进行改进和创新,以方便、快捷、准确地测定根系导水率。

摘  要:
In order to give some references for the application of root hydraulic conductance to the investigation of water transfer in SPAC system,this paper reviewed the research status about the influences of soil water,salts,nutrients,temperature,texture and parasites on root hydraulic conductance.Future research should be conducted to address the influence of time scale(day,month and year) on root hydraulic conductance when investigating the influence of environmental factors on root hydraulic donductance.In order to promote the research of root hydraulic conductance,improvement and innovation of measuring instrument should also be made,aiming at convenient,fast and reliable measurement.
