Scope: This standard specifies the terms and definitions, technical requirements, testing methods, inspection rules, labeling, packaging, transportation and storage requirements for organic substrates used for greening. This standard applies to plant materials such as bark, fallen leaves, crushed branches, bran, wheat bran, rice husks, corn cobs, peanut shells, walnut shells, coconut bran, crop straw, sawdust, reed powder, etc., as well as food The organic matrix for greening is formed by using urban and rural organic waste such as factory scraps (bagasse, dregs, vinegar residue, etc.), traditional Chinese medicine residue, etc. as the main raw materials, adding other auxiliary materials, and after harmless treatment such as stacking and fermentation, crushing and mixing. . Its main purpose is to improve greening soil and partially or completely replace peat or natural soil for greening plant cultivation.
