针刺采胶的针孔排胶影响面呈向右倾斜的纺锤体,长度100～120厘米,宽度10～20厘米。研究表明,分散采胶是扩大针孔排胶面的重要因素。凡有利于扩大排胶面、避免排胶面叠加的采胶方式,都可获得较高产量。在刺激强度和针刺孔数、孔距相同之下,全树周针刺(PC)的排胶影响面比纵带针刺(PI)大,叠加效应较小,产量亦较高。在纵带针刺中.决定其产量的是孔距,而不是孔数,在两孔排胶面范围内增加孔数,对产量并无增益。测定认为,针刺采胶排胶壑区的物质代谢十分活跃,容易建立新的动态平衡。
Needle punching plastic injection pinhole plastic surface is inclined to the right spindle, length 100 ~ 120 cm, width 10 ~ 20 cm. Research shows that dispersed plastic mining is to expand the pinhole plastic surface of an important factor. Where it is conducive to expanding the row of plastic surface, plastic surface row to avoid overlapping plastic mining methods, can obtain higher yield. Under the same stimulus intensity and the number of acupuncture holes and the same hole pitch, the effect of plastic displacement of PC was larger than that of longitudinal acupuncture (PI), with less additive effect and higher yield. In the vertical band acupuncture.Determine its production is the pitch, not the number of holes in the two rows of plastic surface to increase the number of holes, there is no gain in output. Determination, acupuncture mining plastic raft gully material metabolism is very active, easy to establish a new dynamic balance.
