一种测定荒漠草原根系生物量的内生长土芯法

摘要

A device and method was introduced and applied to determine the root biomass of the plant in desert grassland. The results proved that this method could effectively be used to measure the root biomass and net primary productivity of grassland in the desert steppe. It is more suitable to be applied in the desert steppe when the vegetation coverage is low.%介绍了一种测定荒漠草原植物根系生物量的装置与用法,并将其在实际中加以应用.实践证明,本方法可有效测定荒漠草原植物根系生物量及地下净初级生产力,比较适用于植被覆盖度较低的荒漠草原地区.
