摘　　要：低温冻害是树木引种的大敌。南平城区及近郊主要街道和单位引种树种在 1 999年 1 2月 2 1～ 2 3日的低温冻害天气中 ,有 5 3种树种遭受各种程度冻害 ,其中严重冻害 4级以上有 40种 ,地面部分全部冻死的有 2 4种。在今后引种工作中 ,应引起足够重视 。The low-temperature freezing injury is the formidable enemy for tree species introduction.The survey results indicated that in the low-temperature freezing injury weather on December 21～23,1999,53 tree species suffered from the freezing injury with various degrees,among which 40 tree species suffered from the serious freezing injury with over the 4th level and 24 tree species' above-ground portion was killed owing to the freezing.The above freezing injury status should be paid enough attention to so as to reduce the loss in the introduction work afterwards.
