摘要
龙眼、荔枝和果是我国热带、南亚热带（简称热区）名特优水果．这些水果的花芽分化、开花座果对气象条件要求较严格。本文在分析龙眼、荔枝和果的主要气候生态特性的基础上，结合有关省区的气候资料，作出龙眼、荔枝和果生产的布局区划。
he growth of longan (Euphoria stead. ) and lychee (Litchi chinensis Sonn.) requires sufficient sunlight, and high temperatureand hhumidity. The regions, where the annual averagetemperature is from 21℃to 23℃,total accumulated temperatUre(>10℃) from 7500℃ to 8200℃, averase temPeratUre of January from 12℃ to 14℃,extreme minimum temperature > 2℃, and the annual preciptation from 1200mm to 1800mm, are the most suitable to longan and lychee cultivation. The main meterological factors influencing mango (Mangifera indica Linn) growth are also temperature,sunlight and precipitation. The favorable temperature for mango blossoming and fruiting is from 20℃ to 25℃.Rainy day with high humidity and little sunlight is not beneficial to biossoming, fruiting and improvement of fruit quality.Consequently, the valleys where it is clear,warm and dry in the winter are suitable to mango cultivation.
