引言以前的试验结果业已表明,用阴刀割胶时,橡胶树经受强度割胶的能力,比用阳刀割胶时强得多,而且可减少甚至消除因刺激增产而造成的胶树生理疲劳。然而,马来西亚的许多植胶者经常只想到阴刀割胶的缺点,即树皮消耗过多,容易恶化成杀树割胶。其实,很多胶园主要是在更新前几年内的老树上配合双割线制才采用阴刀割胶。在这样很少或没有进行管理的地区,割胶训练十分松懈。因此,阴刀割胶耗皮太多而造成杀树割胶是不奇怪的。新的阴刀割胶制度或其轮换方法,并不意味着杀树割胶,而是有控制的割胶,其目的是,当十二割年以后的产量达
INTRODUCTION Previous tests have shown that rubber trees withstand the strength of tapping when cut with an overcast knife and are much more potent than when tapping with a knife, and can reduce or eliminate the physical fatigue of the gum tree due to increased stimulation. However, many sellers in Malaysia often only think of the disadvantage of overcasting their knives. That is, the bark consumes too much and easily deteriorates into a kelp cut. In fact, a lot of rubber plantation is mainly used in the old tree within a few years before the update with the double secant system before using tapping knife. In such a little or no management area, tapping training is very relaxed. Therefore, the overcast knife cut the skin too much rubber caused by tapping is not strange. The new knife tapping system or its rotation method, does not mean killing the tree tapping, but the control of the tapping, the purpose is that when the twelve cut after the production up to
