在模拟条件下，研究了蚯蚓粪对重要精油作物甘菊（Matricaria chamomilla）生长、产量及重金属积累的影响。与对照（无重金属）相比，施用20 mg kg− 1土壤的镍和镉显著提高了作物的干物质产量。结果还表明，添加蚯蚓粪（在2.5 g kg− 1土壤）增强了金属处理土壤中洋甘菊对重金属的积累。虽然有相当数量的金属被转移到花中，但通过水蒸馏法提取的花精油不含任何重金属。同样，洋甘菊油的化学成分的范围内，从正常土壤条件下生长的洋甘菊。
An experiment was conducted under simulated condition to study the influence of vermicompost on growth, yield and heavy metal accumulation by chamomile (Matricaria chamomilla), an important essential oil bearing crop grown under simulated condition. Nickel and Cadmium applied at 20 mg kg−1soil significantly enhanced the dry matter yield of the crop as compared to the control (no heavy metal). The results also revealed that addition of vermicompost (at 2.5 g kg−1soil) enhanced the heavy metal accumulation by chamomile in metal-treated soil. Although a sizeable amount of metals were being translocated to flowers, the essential oil extracted by hydrodistillation of flowers did not contain any heavy metal. Similarly, chemical constituents of the oil of chamomile were within the range of those obtained from chamomile grown under normal soil condition.
