Sparrows have a great influence on apricot trees. Because of the destruction of sparrows, auspicious tree's buds were swallowed up by sparrows early, which made apricot trees unable to blossom and bear fruit. Therefore, in order to make apricot trees bear more fruits, sparrows must be eliminated.
Because apricot trees bloom early and spring is the season that young people don't want to eat, so sparrows choose flowers on the trees to eat. When apricot trees just bloom, sparrows feed on the buds of apricot trees.
