这种诱导胶树死皮的方法是在常规割胶之前和之后,在割面(割线下方—译注)的垂直针刺带上针刺树皮4或5点,然后用图钉封闭针刺点;每隔一周或二周在前次针刺点的下方重复进行针刺一次。这种技术对于诱导许多品系的死皮均有效。然而,对于参试的品系,在原生皮上和再生皮上的死皮诱导率是不同的。这种在正常割胶强度下诱导死皮的方法,对于研究胶树死皮发生、发展有关的生理参数变化,要比那种基于强度割胶造成死皮的方法更好。 本文还讨论采用这种诱导死皮的方法,其它有关参数诸如胶树产量、胶乳最初流率和干胶含量的变化。上述任一指标是否可以作为胶树发生死皮的早期预报信号,进一步的研究正在进行。
This method of inducing the dead skin of a gum tree involves puncturing the acupuncture points 4 or 5 points on the vertical acupuncture tape before and after conventional tapping, Acupuncture is repeated once every other week or two weeks under the previous acupuncture point. This technique is effective at inducing dead skin on many lines. However, the rate of dead skin induction on native and regenerated hides is different for the tested lines. This method of inducing the dead skin under normal tapping strength is better for studying changes in physiological parameters related to the occurrence and development of the dead skin of the gum tree than that based on the strength of the tapping. This article also discusses the use of this method of inducing dead skin, with other relevant parameters such as gum tree yield, initial latex flow rate, and changes in dry gum content. Whether any of the above indicators can be used as an early prediction signal for the occurrence of dead skin in gum trees is under investigation.
