Scope

Scope: This document specifies the terms and definitions, requirements, testing methods, inspection rules, packaging, labeling, and storage and transportation for vegetable cultivation substrates. This document applies to commercialized mixed substrates used for vegetable cultivation, which are mainly composed of organic substrates fermented from agricultural and forestry waste such as peat and fungal residues, and are mixed with inorganic substrates such as agricultural perlite and vermiculite. Main technical content: 3.1 Vegetable cultivation substrates: Substrates that can replace soil and provide good fertilizer retention, water retention, aeration, and root fixation, thereby providing a normal growth and development environment for vegetable roots. The components typically include organic substrates such as peat and fungal residues, and inorganic substrates such as vermiculite and perlite. 3.2 Bulk density: The mass of a unit volume of vegetable cultivation substrate, expressed in grams per cubic centimeter (g/cm3). 3.3 Aeration porosity: The volume of air occupied in the vegetable cultivation substrate, expressed as a percentage of the total volume of the substrate (%). 3.4 Water retention porosity: The volume of water occupied in the vegetable cultivation substrate, expressed as a percentage of the total volume of the substrate (%). 3.5 Total porosity: The sum of the water retention porosity (%) and aeration porosity (%) in the vegetable cultivation substrate. 3.6 Aeration-to-water retention ratio: The ratio of aeration porosity to water retention porosity in the vegetable cultivation substrate. 3.7 Moisture content: The relative water content in the vegetable cultivation substrate, expressed as a percentage (%). 3.8 Particle size: The diameter of vegetable cultivation substrate particles, expressed in millimeters (mm). 3.9 Electrical conductivity: The electrical conductivity of the vegetable cultivation substrate, reflecting the content of soluble salts, e
