摘　　要：调查研究了2008和2011年年初的低温气候对贵州几种热带作物的影响。结果表明:麻风树受害3～5级,澳洲坚果受害0～1级,火龙果受害3～5级,番石榴受害2～3级,芒果受害3级。因此典型的热带作物果树品种只能在贵州省的低海拔无霜区种植,否则易受低温危害。The effects of low temperature climate at the beginning of both 2008 and 2011 on several tropical fruit trees in Guizhou province were investigated.The results indicated that the injury of low temperature to barbadosnut,macadimia nut,dragon fruit,guava and mango was at 3~5,0~1,3~5,2~3 and 3 level respectively.Therefore,the typical tropical fruit trees could be planted only in the low altitude and frostless districts in Guizhou province,otherwise they would be damaged by low temperature.
