T/JSF 030-2025 Technical Regulation for container seedling cultivation of Acer oblongum

Scope

This document specifies the technical requirements for seed collection and purification, germination, sowing, seedling transplantation, seedling management, nursery preparation, and file management in container seedling production of Acer oblongum. This document is applicable to Acer oblongum seedling production in southern Jiangsu Province. Other regions with similar climatic conditions may refer to and implement it accordingly. The "Technical Regulations for Container Seedling Production of Acer oblongum" is a group standard issued by the Jiangsu Provincial Society of Forestry. The standard details the entire process of container seedling production of Acer oblongum, including seed collection and purification, germination, sowing, seedling transplantation, seedling management, nursery preparation, and file management. Among them, the seeds should be selected from 15-20 year-old Acer oblongum mother trees that have been introduced and domesticated in southern Jiangsu for many years, with robust growth, no obvious pests and diseases, and in the peak fruiting period. After germination by sand storage, the seeds are sown in seedling trays. When the seedlings grow to two pairs of true leaves, they are transplanted into containers and proper seedling management and pest and disease control are carried out. Container seedling can be nursery when they grow to 12 cm to 15 cm. This standard provides a scientific basis for container seedling production of Acer oblongum.
