湖南浏阳金桔生产气候条件及灾害防御

目的]分析浏阳金桔生产的适种农业气候条件。方法]利用浏阳气象观测站1981～2010年的气象资料及浏阳中小尺度区域自动气象观测站资料,结合浏阳气候区划及灾害风险区划,对浏阳金桔生产的适种农业气候条件及灾害防御进行分析。结果]浏阳的光照、温度和降水条件及其时空分布均能满足金桔生长发育的需要,但低温冷害、高温热害、干旱、暴雨、雷雨大风等对金桔的抽梢、开花坐果、膨大和成熟均可能造成显著影响。结论]浏阳有金桔生产适宜的气候环境,但必须重点防御低温冷害、高温干旱、暴雨等气象灾害。

Climate Conditions and Disaster Prevention for Kumquat Production in Liuyang City, Hunan Province

Objective] To study the proper climate conditions for kumquat production in Liuyang City.Method] By using meteorological data of Liuyang meteorological station from 1981-2010 and small and medium scale automatic weather station data,combined with Liuyang climate zoning and disaster risk zoning,the proper climate conditions and disaster prevention for kumquat production were analyzed.Result] Light,temperature,precipitation and its spatial-temporal distribution all can meet the demands of kumquat growth,while chilling damage,high-temperature heat,drought,heavy rain and strong wind have significant effects on shooting,flowering and fruit setting,expand and maturity of kumquat.Conclusion] Liuyang have proper climate environment for kumquat growth,but meteorological disasters,such as chilling,high-temperature drought,heavy rain,should be prevented.
