红壤小流域热带水果产量潜力估算与气候适宜性分析 --以敢上小流域为例

采用联合国粮农组织推荐的“农业生态地带法”,结合层次递减法 ,对敢上小流域龙眼、荔枝、芒果经济产量潜力进行了估算 ,并依据影响龙眼、荔枝、芒果产量的关键气象因子进行气候适宜性分析。结果表明 :敢上小流域适宜发展芒果和早熟龙眼、荔枝 ,不宜发展迟熟龙眼、荔枝 ,要实现果树稳产、高产必须有效克服水分条件对生产潜力的制约

Estimation of output potential of tropical fruits and analysis of the climatic suitability in red soil small shed --A case study of Ganshang shed

With agroecological zonal method recommended by FAO of UN, and hierarchic progressive decrease model, the author assesses the economic output potential of longan, lichee and mango in Ganshang small shed, and analyses the climatic suitability of this fruit trees according to the key climatic factors, which affect the yield of this fruit trees The results show that it is suitable to grow mango and rareripe longan and lichee in Ganshang small shed, but not serotinous longan and lichee In order to achieve the high and steady yield of these fruit trees, the restrictions arised from the moisture condition against the yield potential of these fruit trees must be got over effectively.
