The fruit is not resistant to storage and can be kept for about 1 month. The fruit is mainly used for fresh food.

The height of the 5-year-old tree is 1.9 meters, the stem circumference is 20.3 centimeters, and the crown diameter is 2.0 meters × 2.4 meters. The sprouting power is strong, the bud germination rate is 74.2%, and the branch forming power is medium. Generally, there are 2 or 3 long branches under the cut mouth. The age of the beginning fruit is very early, and it can bear fruit 2 years after planting. Short fruit branches are the main fruit branches, and all kinds of fruit branches can bear fruit.
