Scope
Scope: This document specifies the quality requirements, test methods, inspection rules, quality judgment, packaging, labeling, transportation, and storage of seedling substrates. This document applies to the quality assessment of seedling substrates that are mainly composed of coal gangue and organic materials, which can provide various nutrients for plant seedlings during the seedling stage, regulate the acidity and alkalinity of the soil, and have the functions of promoting seedling growth and disease resistance. Main technical content: The formulation of this standard mainly targets artificially prepared coal gangue seedling substrates, which are mainly used for cultivating seedling growth. Through processing such as decomposition, activation, and passivation of coal gangue, the organic matter, humic acid, nitrogen, phosphorus, potassium, and other useful trace elements contained in coal gangue can be effectively released and easily absorbed by plants for growth.
