摘要
选取不同环境(海拔、坡向,不同品种、不同树龄)的橡胶树对寒害状况进行实地走访调查,从降温过程、性质与特点及橡胶物候、品系(种)、割龄等方面对橡胶树寒害进行分析,结果显示:1以平流为主的混合型降温过程,是多次寒害累加受害的结果。2橡胶树割龄寒害症状从重到轻表现为失管胶林段(前2次寒害达4~6级的割林,受灾后疏于管理,长势弱恢复慢)>老割林段(割龄21~30年)>新割林段(割龄1~20年),橡胶树中幼林基本无寒害。主要查明2013/2014年冬春滇东南植胶区橡胶树寒害情况,总结抗寒植胶经验,提出抗寒植胶建议,为滇东南今后种好橡胶提供科学依据。
Visitin g and survey the different altitude, slope direction and varieties of cutting-rubber tree, middle and young aged rubber tree. slecting 30~100 interlaced and connected plants to observed in each point, from the cooling process, properties and characteristics, and rubber phenology, strain (kind of), cutting age of rubber tree cold injury were analyzed, and the results show that: 1) The cooling and the hybrid of advection cooling,the cooling process is slow and low intensity, the overall rubber tree cold injury and the previous two (2007/2008, 2010/2011)cold injury has a close relationship, it is the result of cold damage accumulation suffer many times. 2) Rubber tree cold injury symptoms from heavy to light cutting age characterized by loss of pipe rubber forest > old cut > new cut; Rubber young and middle aged forests have no cold injury. This article is mainly found the Cold injury situation of rubber tree in 2013/2014 winter and spring southeast Yunnan, sum up the experiences of Anti-cold measure, put forwards the suggestion of Anti-cold measure, and to provide the scientific basis for growing good rubber tree in southeast Yunnan in future.
