摘　　要：怀化为全国柑桔主产区和世界柑桔原生中心之一,冰糖橙种植面积与产量均居世界第一,但周期性冻害对怀化柑桔产业发展造成严重威胁。通过梳理研究1913-2019年怀化历史上柑桔冻害资料,分析总结柑桔冻害的影响因素,提出因地制宜,合理布局;加强品改,调整结构;抓好培管,增强树势;改善桔园小气候,提高桔园冬季温度;选育抗寒良种,推广高砧靠接;深化现代信息技术在冻害领域应用,构建实时监控预警系统等防冻减灾对策。Huaihua is one of the main producing areas of Chinese citrus and one of the core birthplaces of citrus in the world.The planting area and yield of Bingtang orange ranked first in the world,but the cycle freezing damage caused a severe threat to the development of Huaihua citrus industry.According to the data collected from 1913 to 2019,the factors resulted in freezing damage were analyzed and summarized.It presented some countermeasures like reasonable layout,variety improvement,field management,tree pruning,microclimate-attention in orange garden,temperature-adjustment in winter,breeding for cold-resistance variety,high-anvil docking,the application of modern information in freezing damage,constructing real-time monitoring and early warning system and other anti-freezing and disaster-reduction measures,etc.
