土质.污染物对土壤植物群影响的测定 第1部分:抑制根系生长的测量方法

[中文适用范围]： 本部分ISO 11269描述了一种测定受污染土壤或受污染样品对陆生植物根伸长影响的方法。该方法适用于土壤、土壤材料、堆肥、污泥、废物或化学测试。它适用于比较已知和未知质量的土壤，并适用于测量故意添加到土壤中的材料（堆肥、污泥、废物）或化学物质的影响。该方法不旨在用作衡量土壤支持持续植物生长能力的指标。 [外文原描述]： ISO 11269-1:2012 describes a method for the determination of the effects of contaminated soils or contaminated samples on the root elongation of terrestrial plants. This method is applicable to soils, soil materials, compost, sludge, waste or chemical testing. It is applicable to the comparison of soils of known and unknown quality and to the measurement of effects of materials (compost, sludge, waste) or chemicals deliberately added to the soil. The method is not intended to be used as a measure of the ability of the soil to support sustained plant growth.
