产量和树皮消耗量对常规割胶、针刺采胶和刺割结合的采胶制度都是很重要的因素。为了比较这三种采胶制度的产量和耗皮量,进行了试验。也对其他可能影响产量的因子如收胶的方式、施刺激剂的部位和针刺带形状等进行了探讨。 Production and bark consumption are important factors for conventional tapping, needle punching and barbed cutting. In order to compare the production and consumption of these three extraction systems, experiments were carried out. Other factors that may affect yield, such as the type of gel, the location of the stimulant, and the shape of the needling tape, are also discussed.
