【摘要】 2008年1月下旬至2月中旬,我国南方出现了连续低温阴雨天气,给广东垦区橡胶生产造成了巨大损失。对广东垦区橡胶寒害情况进行了调查,结果显示:橡胶中幼龄树寒害以爆皮流胶及干枯混合型为主,品系间存在耐寒性差异,树龄、砧木和环境也显著影响橡胶中幼龄树的受害程度,建议广东省垦区注重使用抗寒品系及抗寒砧木。更多还原

【Abstract】 Low-temperature and rainy weather lasted in the Southern China from the last ten days of January to the mid-February in 2008,resulting in great losses of rubber production in Guangdong province.The investigation results showed that bark burst mixed with the stem drying out was the major symptoms of the chilling injury on Hevea brasiliensis medium and little seedlings.Significant differences in cold resistance were detected between rubber strains.The severity of the damage was influenced by tree ages,rootstocks and environments.Cold resistance rubber tree strains and rootstocks should be used in Guangdong was suggested.更多还原
