Lingshan is located in Guangxi province, with a planting area of over 600,000 mu. Under normal circumstances, it can produce 50,000 tons of litchi every year, including 35 varieties such as Feizixiao and Lingshan litchi. 20 12 Lingshan litchi was protected by geographical indication products. Lingshan litchi is listed from early May to mid-July every year for more than two months, which has the most potential for industrial development.

Litchi growth factor
1, temperature
(1) The suitable temperature for litchi growth is 24-28℃. When the temperature is lower than 12℃, the growth rate will decrease obviously.
(2) Litchi should be allowed to survive in low temperature environment for a period of time in winter to avoid excessive vegetative growth of litchi and promote flower bud differentiation in the following year.
(3) Litchi usually blooms when the temperature is above 65438 00℃ in spring, and it enters its full bloom at around 20℃.
Step 2: Moisture
(1) It is required that the annual precipitation in the planting area should be at least above 1200mm. Litchi has different water requirements at different growth stages, such as less water at flowering stage and good rain shelter.
(2) There should not be too much moisture in the young fruit period to avoid fruit dropping, but it is also necessary to maintain a certain humidity and drain water in time to avoid root rot.
3. Lighting equipment
(1) Litchi also has a high demand for light, and it is required that the annual sunshine in the planting area should be above 1700 hours. Sufficient light can enhance the photosynthetic capacity of litchi, promote flower bud differentiation and improve fruit quality.
(2) However, the light intensity should not be too strong. If the light intensity is too strong, it will increase water evaporation, cause flowers to dry up and reduce pollination and fertilization rate.
