摘要
研究和比较了不同刺激割制对橡胶树RRIM600产胶与生势的影响,包括产量效应、树围增长、死皮率和再生皮恢复等。采用（s/4↑+s/4）d/4+ET1.5％,能够获得比对照高（s/2 d/2）的株产,树干和树皮的增长也有较好的表现,可能是比较安全和高效的割胶制度之一。
Different tapping systems are compared in their effects on yield and growth potential, including latex output, stem girth , tapping panel dryness and bark renewal. Tapping with (s/4 ↑ + s/4)d/4 + ET1.5% can result in higher yield than that of the control (s/2d/2)and in better stem girth growth and bark renewal. It is suitable to adapt the (s/4↑ + s/4) d/4 + ET1.5% tapping system for the RRIM600 trees as a safe and highly efficient one.
