冰冻灾害对庐山植物园猕猴桃生长发育与产量的影响

庐山植物园猕猴桃种质资源．圃位于庐山海拔1100m山林之中，占地面积1 hm2，主要功能是保育保存猕猴桃属优良活体种质资源。庐山冬季时间长，低温持续时间自当年11月中旬至翌年4月上中旬，因空气湿度大而容易形成冰冻，低温冰冻天气主要集中于1—4月。经2008—2010年对猕猴桃冻害调查发现，冰冻对猕猴桃的危害主要表现为：冬芽冻伤、主蔓受冻、根部受冻和果实受冻，并针对庐山的冰冻灾害提出对猕猴桃越冬的防护措施。

The Influence of Cold Injury on the Growth and Yield of Actinidia in Lushan Botanical Garden

The genetic resources collection garden of Actinidia is located at the mountainous region of Lushan Botanical Garden with an altitude of 1100 meters, and covered an area of 1 hectare. In winter and spring of Mt. Lushan, cold weather or humidity are the major reasons that caused cold injury for many Actinidia plants because of long-term low temperature from the mid-November tomid of April next year. The cryogenic freezing weather mainly happened from January to April. By investigation during the years of 2008-2010, the result shows that cold injury of Actinidia includes winter bud frozen damage, stem , root and the fruit frozen damages. Acording to the study, we put forward some protective measures on the winter survival, cold damage protectionto Actinidia at Mt. Lushan
