To study influences of meteorological disasters in the flowering and early fruiting stage on sugar orange industry in Guilin, meteorological disasters in the flowering and early fruiting stage and its defense measures were analyzed and studied. The flowering and early fruiting stage of sug- ar orange in Guilin is from March to June, and sudden change of temperature, thunderstorm, hale, hail, rainstorm and other natural disasters can cause the falling of large numbers of flowers and young fruit, damage of tree body, reduction of fruit in quantity, and decrease of its yield. Timely understanding information of disastrous weather and implementing management of water and fertilizer can effectively reduce the loss caused by meteorological disasters and ensue high quality and high yield of sugar orange.展开更多
Guilin sugar orange has advantages of good taste, harvest during the Spring Festival, marketable market, and it has got swift and violent development in recent years.

Sugar orange yield and quality is closely related to meteorological conditions, so in order to study the effect of meteorological conditions on the Guilin sugar orange, the local conditions of each orange-planting county in Guilin is analyzed, and study is also carried out on the severe weather and its defense measures. The suitable growth temperature for sugar orange is 23-29 ℃, and sugar orange is not tolerant to waterlogging and drought, like light, and has no resistance to ice cold. The main meteorological disasters include high temperature, low temperature, flood, drought, wind, hail, etc. Reasonable selection of orchard, scientific management, especially the management of plant diseases and insect pests, is the key to ensure high-quality high sand sugar orange.展开更多
