2. The degree of leaf removal: all the leaves in the 5cm range of the crown and the outer fruit and the 10-12cm range of the fruit under the crown were removed.

3. 5-6 days after picking leaves, gently drag the fruit by hand to turn its direction, in order to promote its overall coloring, and then continue to turn its fruit in the upward direction after 5-6 days, so as to improve fruit quality and commodity value.
