Yes, adjust the opening angle of branches in autumn to improve ventilation and light transmission, improve fruit quality, adjust tree potential and promote flower bud differentiation. Thinning: pruning dense, overgrown and diseased branches and tillers. The light spots under the canopy are required to be sparse and evenly distributed on the ground. Ensure that the fruit can directly see the light, so that the leaves and short branches in the inner room can see enough light to quickly form flower buds.
