(1) Emphasizing on reducing soil moisture content before fruit picking, moderate drying of soil before fruit picking is beneficial to reducing nitrogen fertilizer effect, concentrating fruit juice, increasing sugar content and maintaining high acidity, so as to make fruit flavor strong. In the area where autumn rain often occurs, the method of reducing soil moisture holding capacity of orchard before harvest can be carried out by plastic film covering to prevent rain and reduce moisture except high chamber deep ditch.

Timely harvest: It is also an important measure to ensure the quality of citrus fruits. In frost-free areas, the use of hanging trees can increase sugar by 1-2 degrees, and the fruit color is more vivid.

Harvesting carefully and reducing fruit damage rate is one of the effective measures to improve fruit storability. After harvest, fruits should be treated with preservatives within 24 hours, which is beneficial to improve the healing and storage resistance of slightly injured fruits. The fruits treated by chemicals should be stored in the pre-storage room first.
