摘 要: | 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 |
| |
Abstract: | 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 |
