What principles should be followed when pruning jujube trees during the fruiting period

Principles for pruning jujube trees during the fruiting period: maintain a canopy structure with good ventilation and light penetration, so that the branches are evenly distributed, and carry out planned renewal and rejuvenation of the fruiting branch groups; each branch group must maintain a relatively long fruiting lifespan, so that the tree ages but the branches do not, maintaining a high fruiting capacity over the long term. In early-stage pruning, mostly make heading cuts at the thick, strong part of the jujube shoot, and remove several secondary branches below the cut. During this period, summer pruning consists only of bud removal, with little pinching.
