Abstract:

The experiment of micro-cut tapping with ethylene gas stimulation on the old renewal rubber trees had been done in Hainan, which was guided to update rubber tree tapping potential and enhance economic efficiency. In this experiment, micro-cut tapping with ethylene gas stimulate was used on 3 different strains of the old renewal rubber trees compared with conventional tapping method. The results showed that the yield was increased, the highest being more than 61.9%, the dry rubber content was lower slightly, the tapping time was shorten 50%, and the speed was raised by 1 times as compared with the control. Micro-cut tapping with ethylene gas stimulate was one new efficiency technology. And it would be one better application prospect for renewal rubber trees.
