摘　　要：察隅县属亚热带气候区,适合种植部分热带果树。为探明在该地种植热带果树可能性及种类, 2017年4月引进一批热带果树进行试种,对当地冬季气温、空气湿度、降雨量、光照强度、风速和风向等气象数据进行测量,观测引种的各种果树经过冬季极端气候后生长表现,发现澳洲坚果、荔枝、黄皮和果桑4种果树生长良好,咖啡、莲雾和番荔枝3种果树全部死亡,芒果、菠萝、台湾青枣和火龙果长势一般。通过对比气象数据、地理位置和果树长势,初步得出了察隅县属热带果树种植的北缘区,在该地可以种植澳洲坚果等耐寒性较强的热带果树的结论。Chayu county,Tibet is a subtropical climate zone,where some tropical fruit trees may be suitable for planting.A batch of tropical fruit trees were introduced for trial planting in April 2017 to explore the possibility of planting tropical fruit trees in this area.The meteorological data,such as local temperature,air humidity,rainfall,light intensity,wind speed and wind direction in winter,were measured,and growth performance of the fruit trees introduced was observed after extreme weather in winter.It was found that macadamia,litchi,wampee and mulberry grew well,that coffee,wax jambu and Annona were all dead,and that mango,pineapple,Zizyphus mauritiana and pitaya had average growth vigor.Comparison of these fruit trees in meteorological data,geographical location and the growth performance showed that Chayu county is located at the northern edge of the area with plantation of tropical fruit trees,where some high cold-tolerance tropical fruit trees such as macadamia can be planted.
