The results of physical and chemical quality test are as follows: soluble solid content 18.3%, edible rate 80.5%, total sugar content 15.0%, vitamin C content 27.0 mg/10g, titratable acid content 0.10%.

1. Variety Name: Fei Crisp Litchi

II. Variety type: Litchi

III. Breeding units: Fruit Research Institute, Academy of Agricultural Sciences of Guangdong Province, Fruit Science Research Institute of Maoming City, Fruit Bureau of Dianbai District, Maoming City

IV. Suitable planting area: suitable for litchi planting in Guangdong Province.

V. Variety source: selected from litchi trees in fruit field of Dianbai Port Bureau, Mata Town, Dianbai District, Maoming City

6. Per mu yield: physiological fruit drop is less, fruit cracking rate is low, high and stable yield The average plant yield in the third, fourth and fifth years of seedling planting is 4.8 kg, 8.4 kg and 9.7 kg respectively, equivalent to 124.8 kg, 218.4 kg and 252.2 kg per mu respectively.

3. Fruiting trees were pruned within one month after harvest, and shoots were put out once in the first half of August and the last half of September respectively.

4. After the last autumn shoot ripens, ring cutting or spiral girdling is carried out on the big branch to control the shoot and promote the flower. The reasonable fertilization is carried out during the fruit development period, mainly with decomposed organic fertilizer. After the second physiological fruit drop, the fruit is thinned, leaving 10 small fruits per ear.
