Hawthorn trees have been widely managed and pruned for a long time, but in order to promote high yield, reasonable shaping and pruning must be carried out on the basis of soil, fertilizer and water management. According to the characteristics of hawthorn tree, such as light-loving, strong dryness and obvious bedding, it is appropriate to adopt sparse trunk and natural shape-loving. Stage pruning of young trees mainly includes shaping, cutting more and not thinning, expanding crown by blasting and cultivating backbone branches. At the initial stage of fruiting, besides modeling, it is necessary to cultivate fruiting branches, strengthen upright branches and release them slowly to promote their fruiting, and continuous fruiting branches will be retracted in time; Competitive branches with space can be cultivated into fruiting branches. In the full fruit stage, the fruiting branches should be thinned or retracted, the peripheral branches and inflorescences should be shortened, the growth of vegetative branches should be strengthened, and the over-dense branches, overlapping branches, cross branches and combined branches should be thinned. Results In the regeneration period, on the basis of strengthening the management of soil, fertilizer and water, the backbone branches at all levels were retracted year by year, and the fruiting branches were re-cultivated with long branches, so that the trees were rejuvenated and the fruiting life was prolonged.
