This standard stipulates the minimum yield and quality indicators that should be achieved in the young forest stage, mature stage and mature technology of artificial high-yield red spruce (Piceak oraiensis) forests. It also specifies the main fast-growing and high-yield measures that should be taken to create high-yield red spruce forests. technology. This standard applies to state-owned, collective and individual red spruce high-yield forests established in red spruce producing areas.
