海南省2007/2008年冬橡胶树寒害情况浅析

Analysis on Rubber Tree Cold Injury in 2007/2008 Winter in Hainan

为了系统掌握此次低温寒害的特点和规律,弄清其对海南垦区天然橡胶生产的影响,比较品种、不同年龄橡胶树对持续低温的反应和适应情况,了解各种栽培技术措施的抗寒效果,积累中国橡胶树寒害资料并及时总结防寒抗灾的经验,为中国橡胶树抗寒栽培和选育种技术的日益完善提供科学依据。调查了海南省2007/2008年冬橡胶树寒害情况,从寒害的气候特点、生态类型区、品系(种)、树龄、地形、立地环境等方面对橡胶树寒害特征进行了分析,为海南的抗寒植胶、橡胶树新品种的应用积累了新的资料,并针对防寒抗灾提出建议。

System in order to grasp the low-temperature characteristics and patterns of chilling injury, to ascertain its reclamation area of Hainan natural rubber production, compared varieties of rubber trees of different ages of continued low-temperature reaction and adapt to the situation, understanding the various cultivation techniques measure the effect of the cold, the accumulation of China＇s rubber tree cold injury information and timely summary of the experience of cold protection, cold for the Chinese rubber tree cultivation and selection of the increasingly improved breeding techniques to provide a scientific basis. The rubber tree cold injury in 2007/2008 winter in Hainan province had been investigated. By analyzing temperature climatic feature, and ecological types, the effect of clones, age stages, landform and the location condition, it expands the knowledge on planting of cold resistance, and enriches the applying documentation on new rubber clone. Further, pertinence suggestion is put forward on cold protection.
