标准范围

本文件规定了从陆地农田土壤中采集和处理自由生活线虫的方法，作为将其用作生物指示剂的先决条件（例如，评估土壤作为生物体栖息地的质量）。本文件适用于发生线虫的所有陆地生物区。ISO 18400-101规定了现场研究的抽样设计。由于样品基质（例如水柱）的差异，本文件不适用于水生线虫。其他一些土壤生物类群的方法，如蚯蚓、内生棘线虫或巨龙-无脊椎动物包含在ISO 23611-1、ISO 23611-2、ISO 236101-3和ISO 23611-5中。本文件未涵盖采样土壤无脊椎动物时高度推荐的场地土壤特征。ISO 10390、ISO 10694、ISO 11272、ISO 11274、ISO 11277、ISO 11461和ISO 11465包括测量pH值、粒度分布、C/N比、有机碳含量和持水能力的适当程序。

This document specifies a method for sampling and handling free-living nematodes from terrestrial field soils as a prerequisite for using them as bio-indicators (e.g. to assess the quality of a soil as a habitat for organisms).This document applies to all terrestrial biotopes in which nematodes occur. The sampling design of field studies in general is specified in ISO 18400-101.This document is not applicable to aquatic nematodes because of differences in the sample matrix (e.g. water column). Methods for some other soil organism groups such as earthworms, collembolans enchytraeids or macro-invertebrates are covered in ISO 23611-1, ISO 23611-2, ISO 23611-3 and ISO 23611-5.This document does not cover the pedological characterization of the site which is highly recommendable when sampling soil invertebrates. ISO 10390, ISO 10694, ISO 11272, ISO 11274, ISO 11277, ISO 11461 and ISO 11465 include suitable procedures for measuring pH, particle size distribution, C/N ratio, organic carbon content and water-holding capacity.
