What growth and development characteristics does a jujube tree have during the fruiting renewal stage?

The fruiting renewal stage of a jujube tree is the late period of vigorous fruiting. The base branches on the trunk and main branches begin to decline, the main branches bend and droop, and latent buds or adventitious buds on the main branches sprout into vigorous new shoots that extend parallel to the trunk. The inner canopy becomes hollow, the fruiting area shifts outward, and yield declines year by year. During this stage, some root-sucker seedlings can extend to 100 years.
