求翻译： To estimate root biomass, 20 shrubs of different volumes and ages were removed completely from each site and the root biomass of each shrub was collected and weighed. All roots found at each depth (0–20, 20–40, 40–60, 60-80cm) were retained in a 2 mm sieve.是什么意思？ 待解决

要估计根生物量，不同的容量20灌木和年龄从每个站点完全地被去除，并且每灌木根生物量收集了并且被称了。所有根被找到在每深度(0-20， 20-40， 40-60， 60-80cm)在一个2 mm筛子保留了。
