采用常规的 d/2割制结合连续刺激时,乙烯丰的刺激效应会逐渐降低。早期已用乙烯丰刺激的胶树,在以后的割面上继续刺激时,则会产生负效应。因此,目前正注意运用强度较低的割制。此外,由 With conventional d / 2 cutting combined with continuous stimulation, ethylene abundance stimulating effect will gradually reduce. Glue trees that have been stimulated with vinyl early in the early stages will have a negative effect when they continue to be stimulated on subsequent cuts. Therefore, attention is now being given to the use of less intensive cutting. In addition, by
