摘要
采用中国热带农业科学院橡胶研究所研制的橡胶树死皮康复营养剂和死皮防治涂施剂,对死皮停割的云研77-4和GT1进行药剂防治试验,以对其施用效果进行评价。结果表明:施药处理2年后,云研77-4和GT1的死皮长度恢复率分别为71.78%和61.32%,均高于对照;GT1的植株产量(45.34 g/株)明显高于对照(17.46 g/株)。云研77-4复割植株持续割胶4个月内,处理植株与对照植株产量变化趋势一致,但处理植株死皮指数在测产后期比对照降低明显。结果说明,死皮康复营养剂能明显降低橡胶树死皮停割植株死皮指数及促进割线症状的恢复,且能提高死皮植株产量,在产胶方面也更具有可持续性。
Tapping panel dryness (TPD)-controlled nutritional agents (paste + solution) developed by Rubber Research Institute, Chinese Academy of Tropical Agriculture Sciences were applied by brushing and spraying onto rubber trees of Yunyan77-4 and GT1 under rest due to tapping panel dryness to observe their effect on recovery of rubber trees for tapping. The results showed that after two years of treatment clones Yunyan 77-4 and GT1 recovered 71.78% and 61.32% of the cut length of TPD, respectively, which were better than that of the control. And the GT1 rubber trees treated yielded significantly higher (45.34 g/plant) than the control (17.46 g/plant). During four months of tapping the Yunyan 77-4 rubber trees treated tended to have a relatively stable yield change which was similar to that of the control. However, the rubber trees treated had significantly lower TPD incidence than the control at the late stage of yield measuring. These results indicate that the TPD-controlled nutrient agents decreased obviously tapping panel dryness incidence, recovered the cuts from TPD symptoms, increased yield of the TPD rubber trees, and contributed to much sustainable latex regeneration of rubber trees.
