It has fine pulp, slow aging, and good quality. The seedlings have strong cold resistance, early seeding and fast seedlings, strong disease resistance, early flowering and fruiting, strong adaptability, and can be planted in the spring and autumn, with high yield in the early stage. General yield of 1750 to 2000 kg per mu. Evergreen 102 This species is sprawling, growing more than 2 meters long, with fewer lateral branches and low scab-nodes. The first pick (litchi) is born in 2 to 3 knots. The flower is purple, green and tender green, with a length of 80 to 90 cm and a length of more than 1 meter.
