Problems solved by technology

However, the existing flower thinning equipment often has the following defects: (1) A large number of repeated field experiments are required to determine the optimal value of each operating parameter in the mechanical device, which reduces the economic benefits of the fruit grower, thus seriously affecting the fruit grower's ability to plant fruit trees. (2) The flower thinning device cannot be accurately matched with the target flowers, thus reducing the accuracy of the flower thinning operation to a certain extent
