摘　　要：以橡胶树无性系热研8-79为材料,分析一种新型排胶调节剂对胶乳产量、干胶产量、茎围增长、树皮结构和死皮发生的影响。结果表明:新型排胶调节剂在高温季节有明显的增产效应,胶乳产量和干胶产量分别增长23.38%和16.01%;新型排胶调节剂能有效降低死皮发生率,仅为2.22%,而且能促进乳管分化,对茎围增长没有明显的抑制效应。结果说明新型排胶调节剂具有高效性和安全性。The effect of a novel latex flow regulator on the latex production, rubber yield, girth increment, bark structure and occurrence of tapping panel dryness（TPD） were analyzed. Results showed that the regulator caused the latex production and rubber yield to be increased by 23.38% and 16.01% in the moths with relatively high temperature, respectively. It also reduced the TPD occurrence. The rate of TPD occurrence was 2.22%, the lowest in comparison with 0.5% ethrel and that without any treatments. And moreover, it could induce the secondary laticifer differentiation and had little influence on stem girth increment. Therefore, the novel regulator is characterized by its high efficiency and safety.
