根际微域研究中土样采集方法的研究进展

Advance in soil sampling methods in rhizosphere microzone study.

综述了 60年代以来植物根际微域研究中土壤样品的采集方法 ,认为根际土样采集的发展趋势是从田间的粗略采集到室内模拟实验的精细划分 ,再把模拟装置运用到田间 ,最终达到指导生产的目的 .同时 ,随着根际概念的拓宽 (生态界面Eco boundarylayer) ,根际土样的采集朝着保持原位和更精细的方向发展 .

Soil sampling methods in rhizosphere microzone study since 1960's were reviewed. It was suggested that the trend of rhizosphere soil sampling was from field coarse sampling to fine division of indoor simulated experiment. The simulated equipment was applied for field experiments, and the purpose guiding production practice could be achieved finally. Meanwhile, with the widening of the concept of rhizosphere, such as ecoboundary layer, rhizosphere soil sampling tends to keep unvarnished and fine.
