The invention discloses a fruit tree thinning and planting technology, and relates to the technical field of fruit tree pruning. The fruit tree thinning and planting technology comprises the followingsteps: SS01, pruning at a young tree stage; SS02, pruning at an initial fruit stage; SS03, pruning at a fruiting stage; SS04, pruning at a full fruit period; and SS05, pruning at a senescent stage. According to the invention, a specific pruning method is carried out on the growth period of the young tree stage, the initial fruit stage, the fruiting stage, the full fruit stage and the senescent stage of the fruit trees, the top-end advantage is weaken through regular pruning in summer and winter, the space of tree branches can be reasonably utilized, and illumination conditions and ventilationeffects inside the tree branches can be guaranteed, diseases are reduced through pruning of persistent main branches and pruning of temporary branches, the numbers of main branches, lateral branchesand fruiting branches are guaranteed, and the circumstance that too many fruiting branches cause too small fruits is avoided, or the circumstance that less fruiting branches cause less fruiting quantity is avoided, and the problem that the growth efficiency of the fruit trees is low due to the fact that an existing pruning method of the fruit trees is not standard is solved.
