The flowering quantity of most fruit trees is far more than that of the fruit which is finally grown, the flowering and fruiting are excessive, nutrient supply is not required, normal development of the fruit is influenced, a plurality of small fruits and secondary fruits are formed, the tree vigor is weakened, the tree is easy to be damaged by freezing and infected by diseases, the yield is reduced in the next year, and the yield is small. Therefore, besides the flowers and young fruits which are not developed naturally fall off due to the self-regulating ability of the fruit trees, the excess flowers and fruits are also needed to be removed so as to meet the production requirements.
The flower and fruit thinning operation is a link with strong seasonality, high labor intensity and high operation requirement in agricultural production.
