| 摘 要： | 研究不同割胶制度对橡胶树优良无性系热研8-79幼龄树的产量、干含及蔗糖、硫醇、无机磷、镁离子等指标的影响。认为在热研8-79投产初期应以低浓度乙烯利刺激为宜,采用S/2d/4+ET0.25％割制具有产量高、蔗糖及硫醇含量高、胶乳稳定性增强的优势。指出对该品种采用低频、低浓度刺激的同时必须结合提高生产管理水平,从而达到高产、高效、安全的目的。

| Abstract: | The effect of different tapping systems was studied on promising rubber clone SCATC 8-79 in yield, dry rubber content and the content of sucrose, phosphorus, thiol and Mg2+. It showed that the low ethylene concentration is appropriate in the first yielding period and S/2d/4 +ET0.25% has preponderances in high yield, high of content sucrose and thiol and enhancing latex stability. It was suggested that with suitable management, adopting the tapping system of low ethylene concentration at low frequency can reach the goal of high yield, high efficiency and safety. |
