摘　　要：The yield of sugar orange is closely related to meteorological conditions in the flowering and fruiting period, and meteorological disasters at the flowering and early fruiting stage seriously affect its yield. 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.沙糖桔的产量与花果期气象条件密切相关,保花保果期气象灾害严重影响后期产量。为研究保花保果期气象灾害对桂林沙糖桔产业的影响,对桂林沙糖桔保花保果期气象灾害的天气防御措施进行分析和研究。桂林沙糖桔保花保果期指每年3~6月,沙糖桔开花及幼果生长期,此时的温度突升突降、雷雨大风、冰雹、暴雨等灾害会造成大量花朵或幼果脱落,树体伤害,挂果数量减少,产量下降。及时了解灾害天气信息,及时做好水肥管理,可以有效减少气象灾害带来的损失,保证沙糖桔优质丰产。
