摘  要：
根据芒果对低温的要求,将芒果低温危害分为轻度、中度、重度和严重4个等级指标,统计望谟县1968—2017年50年间极端最低气温,分析其对芒果不同受害等级的年度及日期分布特征,以期为低温灾害的监测预警服务及合理化、规模化发展芒果产业提供理论依据。结果表明,望谟县芒果易受轻度和中度低温危害,也有重度和严重低温危害,但危害几率不大。在极端低温时间分布方面,各种等级的危害时间主要集中在12月下旬至1月上旬。因此,今后望谟地区要重视中度低温危害,预防轻度低温危害,可采用加强芒果树体管理,提高树体营养水平,控制冬稍抽生和早生花穗,加强冬季防冻处理等对策措施。

摘  要：
Conclusion:In order to provide monitoring and early warning for low temperature disasters for mango in winter and develop mango industry on a reasonable scale. According to the low temperature requirement of mango,the low temperature hazards of mango were classified into four grades:light,mild,serious,more serious. The extreme minimum temperature was calculated in Wangmo County from 1968 to 2017,The annual and date distribution characteristics of mango in different damage grades were analyzed,the distribution characteristics of extreme minimum temperature on different victimization grades of mango were analyzed. The results showed that mango was easily damaged by light and mild low temperature in Wangmo County,however,Serious,More serious low temperature hazards also occur,but the probability was very small. In terms of extreme of low temperature distribution of dates,various levels of hazards were concentrated between late December and early January. Conclusion:Prevention work should be paid attention to the light and mild low temperature hazard in Wangmo county.We should strengthen the management of mango trees,improve the nutritional level of mango trees,control the emergence of winter shoots and early spikes and strengthen the anti-freezing treatment in winter.So as to reduce the loss caused by light and mild low temperature hazards.
