摘    要:根据龙眼生物学特性、产量和气候资料,通过平行分析和数理统计方法,对气候条件影响广西地区龙眼产量的关键时期和关键因子进行了研究。结果表明:气候条件影响广西地区龙眼产量的关键时期为晚秋梢生长期、花芽分化期和开花座果期,关键气候因子分别为气温、雨量、雨日和日照时数。在此基础上,结合典型年份气候要素与产量的对比分析,确定了丰歉气候指标,为龙眼的栽培管理提供了科学依据,同时也为开展龙眼气象服务提供了技术支撑。

关 键 词:气候条件  龙眼  产量  关键时期  气候指标

Abstract:According to the biologic characteristic of the Longan and the data of yield and climate during its growth, by the methods of parallel analysis and mathematical statistic, it is studied in this paper the key stages and key climate factors that affect Longan yield in Guangxi region. The result indicates that key stages include the growth stage of late autumn treetop, bud differentiation stage and anthesis stage, and that key climate factors are temperature, precipitation, rainfall days and sunlight time. Based on the key stages and factors, by the analysis to climate factors and yield of typical years, the climate index of rich and poor harvest in three key stages was decided respectively, which can provide scientific reference for planting and management of the Longan and technique support for developing meteorological service for the Longan production as well.
Keywords:climate condition  the Longan  yield  key stage  climate index
