| 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,对死皮停割的‘云研77-4’和‘GT1’进行药剂防控试验。结果表明:施药5个月后,参试的‘云研77-4’死皮发病率和发病指数均呈下降趋势,防效为23.1%,且死皮级别在3级以下的橡胶树死皮长度恢复率(45.1%)要好于死皮级别4~5级的橡胶树(17.6%),而参试的‘GT1’处理后效果不明显。对恢复产胶的植株持续割胶后,处理的产胶量与对照相比也较稳定。由此得出,该药剂对‘云研77-4’3级以下死皮的恢复效果较好,对4~5级死皮也有一定的防治作用。

Control of Tapping Panel Dryness (TPD) of Hevea Rubber |

| Abstract: | Rubber trees of Clon es ‘Yunyan 77-4’ and ‘GT1’ that stopped tapping for rest due to suffering of tapping panel dryness (TPD) were treated with a TPD nutrient agent developed by the Rubber Research Institute of Chinese Academy of Tropical Agriculture Sciences. The results showed that the incidence rate and index of TPD of ‘Yunyan 77-4’ tended to decrease after 5 months of treatment. The TPD control rate was 23.1%, and the TPD length recovery rate at severity grades of 1 to 3 was 45.1%, much higher than that at 4~5 grade (17.6%), while the ‘GT1’ had no obvious effect after the treatment. The treated TPD rubber trees were tapped successively and yielded more stable than the control. Thus, this TPD nutrient agent had a better effect on rubber clone ‘Yunyan 77-4’ that had a TPD severity below grade 3, and also had certain control effect on TPD rubber trees at the TPD severity grades 4~5. |
