【摘要】 2017—2018年在云南省保山市隆阳区潞江镇新寨村海拔760、978、1 270、1 440、1 640 m各设1个观测点，研究不同海拔高度下咖啡种植生态环境并综合咖啡杯测进一步探讨咖啡种植的理想海拔高度。结果表明，随着海拔升高，年均气温和年太阳曝辐量下降，降水量、土壤养分有效性增加，咖啡花期、果期推迟，咖啡杯品分值呈上升趋势，海拔高度与杯品分值呈正相关。但海拔超出1 500 m时，产量严重下降，空瘪率高，且采收期正逢雨季。综合来看，中海拔区域（978、1 270、1 440m）种植的咖啡综合表现较好，均达到精品级。更多还原

【Abstract】 From 2017 to 2018, one observation point was set up at an altitude of 760, 978, 1 270, 1 440 and 1 640 m respectively in Xinzhai Village, Lujiang Town, Longyang District, Baoshan, Yunnan, to investigate the correlation between altitude and coffee quality. The results showed that as the altitude increased, the average annual temperature and solar exposure decreased, precipitation and soil nutrient availability increased, flowering and fruiting periods were delayed, and the coffee cup score showed an upward trend. The altitude was positively correlated with the cup score. But when the altitude exceeds 1 500 m, the yield seriously decreases, the hollowing rate is high, and the harvesting period coincides with the rainy season. Overall, coffee grown in mid altitude areas(978, 1 270, 1 440 m) performs well and has reached the premium level.更多还原
