Pruning: Pruning mainly solves the contradiction between vegetative growth and reproductive growth, and increases fruit setting rate. Most blueberry varieties are semi-orientated or semi-opened. When pruning, they can be visually observed for age, branches, and flower buds. The blue saplings of high-cone blueberries and rabbit eyes are pruned to remove flower buds, and the trees are mainly controlled to control tree height and thinning branches. Dwarf plexus blueberry is mainly used to maintain strong trees and strong branches.
Pest control: The diseases and pests commonly occurring in the cultivation of blueberries in foreign countries include frozen fruit disease, powdery mildew, mosaic disease, root cancer, aphids, and roundworms. In China, diseases and insect pests are rare. In Jiangsu Province, two species of pupa pests, C. sinica and C. argenteus, have been found in rabbit eyes. In the prevention and control, comprehensive measures such as natural enemies, improvement of ecological environment in orchards, and chemical control were adopted.
