土壤质量.取样.第206部分：实验室微生物过程、生物量和多样性评估用需氧条件下土壤的收集、处理和储存

[中文适用范围]： 此文档提供了在实验室好氧条件下进行后续生物测试的土壤采集、处理 and 存储的标准程序。它适用于评估土壤对微生物、无脊椎动物（例如：生存、繁殖、生长、行为）和植物（例如：发育、生长）影响的采集、处理和存储。此文档不适用于需要 throughout 保持厌氧条件的土壤处理。此文档描述了如何最大限度地减少温度、含水量、氧气可用性的差异以及土壤颗粒分级对好氧过程的影响，以促进可重复的实验室测定。此文档主要适用于温带土壤。从极端气候（例如：永久冻土、热带土壤）收集的土壤可能需要特殊的处理。注：此文档不提供在田间评估土壤有机体群落结构和功能时收集、处理和存储土壤有机体的标准程序。此类标准程序在 ISO 23611-1 至 ISO 23611-6 中提供。 [外文原描述]： This document provides standard procedures for the collection, handling and storage of soil for subsequent biological testing under aerobic conditions in the laboratory. It applies to the collection, handling and storage for assessing the effects of soil on microorganisms, invertebrates (e.g. survival, reproduction, growth, behaviour) and plants (e.g. development, growth). This document is not applicable to the handling of soil where anaerobic conditions need to be maintained throughout. This document describes how to minimize the effects of differences in temperature, water content, and availability of oxygen on aerobic processes as well as the fractionation of soil particles to facilitate reproducible laboratory determinations[1][2]. This document is mainly applicable to temperate soils. Soils collected from extreme climates (e.g. permafrost, tropical soils) can require special handling. NOTE This document does not provide standard procedures on the collection, handling and storage of soil organisms when assessing the structure and function of soil organism communities in the field. Such standard procedures are provided in ISO 23611‑1 to ISO 23611‑6.
