| 摘 要： | 为探明侨植农场砖厂附近橡胶树的受害原因，对受害橡胶树的表现症状、土壤、叶片养分及氟化物含量进行调查。结果表明：受害胶树的症状与植物生理学上氟化物伤害症状相符，排除了病虫害等致害因素；受害胶树周围土壤的主要养分指标处于正常水平，土壤养分不存在亏缺状态；受害胶树叶片的主要养分指标同样处于正常水平，叶片不存在缺素症状；受害胶树周围土壤和叶片中的氟化物含量显著高于正常值水平。鉴于该砖厂为受害胶树附近唯一的氟化物污染源，因此认为该砖厂排放的氟化物是导致胶树受害的主要原因。

| Abstract: | Based on investigating the revealed symptoms, soil nutrient, leaf nutrient and fluorine content of the damaged rubber tree nearby the affiliated brickyard of Hainan Qiaozhi farm, we analyzed the reason for the damage in this study. The results showed that the damaged symptoms of the impaired rubber trees physiologically conformed to the ones suffered by fluorine, so the damage induced factors such as pest could be eliminated. The main nutrient index in the surrounding soil of damaged rubber trees ranged normally, so there was no nutrient limited status in soil. And the main nutrient indexes of the damaged tree leaves were on the regular level, which meant that the nutritional deficiency symptom didn't exist. The only suspected observation was that the fluorine content in the surrounding soil and leaves of the damaged rubber trees was significantly higher than the regular background value. In summary, in view of the fact that the unique nearby drainage of fluorine pollutant source came from the brickyard, we suggested that the fluorine from the brickyard was the major reason for the rubber tree damage. |
