Fruit thinning method for preventing citrus reiculata Blanco from bearing fruits in biennial and minor years

The invention provides a fruit thinning method for preventing citrus reiculata Blanco from bearing fruits in biennial and biennial years, and belongs to the technical field of fruit tree pruning. The method comprises the steps of pruning and partial pruning. In the pruning step, 1-2 relatively thick and strong branches are selected for fruit trees which are large in fruit bearing amount and difficult to shoot, and are retracted to the positions where all fruits are cut off or the positions of the branch tips of the upper stage on the selected branches; the partial pruning means that the top parts of bunched fruit branches are pruned from proper positions at a time according to the fruit insertion position, the branch length, the thickness (the thickness of the middle of a stem), the tenderness degree and the fruit carrying amount as the judgment basis for bearing branches needing fruit thinning. The fruit thinning frequency can be reduced, and the labor cost input is reduced; the fruit thinning time is shorte
