云南热作所微割采胶试验总结报告

报道云南最早进行橡胶树微割采胶试验的结果。结果表明，微割采胶的株产、株次产都高于对照常规割胶，年平均净增产率为5．78％，干胶含量比对照低1～4个百分点；割胶速度为对照的2～3倍；耗皮量为对照的20％-25％；累计死皮率为4．04％，低于对照（5．91％），为常规割胶的68．36％，胶乳生理参数保持正常水平。

A Report of the Micro-cut Tapping Test at Yunnan Institute of Tropical Crops

The first trail of micro-cut tapping （Mc） in Yunnan was carried out at YITC （Yunnan Institute of Tropical Crops）. The results showed that the yield per tree or per tree per tapping were higher than that of control with conventional tapping system, with an average net increase rate of 5.78%. The DRC from micro-cut tapping was 1% --4% lower than that of control. Tapping speed was 2 to 3 times of the control; the bark consumption was 20% - 25% of the control. Accumulated TPD was 4.04%, lower than that of control （5.91%）. The physiological parameters of Mc latex maintained normal levels.
