In autumn, pomegranate trees often sprout many new shoots two or three times, which makes the branches of the crown dense, leading to poor ventilation and light transmission, slow fruit growth and poor coloring. Therefore, it is particularly important to strengthen autumn pruning.

First, thinning branches, cutting off dense, overgrown sprouting branches and tillers with diseases and pests, and then sticking a callus antiseptic film at the pruning opening to protect the wound tissue from healing and prevent the invasion and infection of germs; It is also required that the light spots under the crown after thinning are evenly distributed on the ground, which should account for 10% ~ 15% of the projected area of the crown. Bury or burn the cut fruit branches with pests and diseases, and spray the trees in the whole garden for disinfection to reduce the source of germs.

2. Root pruning: from mid-June, 65438+ 10 to June 165438+ 10, that is, pruning the root system after fruit picking and before defoliation. According to the fruiting situation of pomegranate trees, organic fertilizer can be applied in autumn with hole expansion. Digging annular or parallel ditches (depth 50 ~ 100 cm) around the crown and cutting off some roots with diameters less than 1 cm are beneficial to root regeneration and expansion.
