老龄胶树可采用1/4S割制、1/4S割面轮换制度或常规的1/2S低频平割制配合乙烯丰刺激在低割面进行高效割胶。在低割面经过一个时期的强度割胶后,在高割面采用阴刀割胶制度仍然可以获得高产。不可能进行阴刀割胶的胶树,在其高割面用1/2S割制配合乙烯丰刺激,可以获得中等的产量。砍伐前可以采用高、低割面双线配合乙烯丰刺激进行短期割胶。高割面刺激割胶会导致胶乳产量大增和干胶含量相对降低。高割面阴刀割胶制度的长流胶比例相对较高。
Aged gum trees can be 1 / 4S cut, 1 / 4S cut face rotation system or conventional 1 / 2S low-frequency flat cut with ethylene Fen stimulation in the low cut surface for efficient tapping. After a period of low-cut strength after tapping, high-cut face using tapping knife system can still get high yield. It is impossible to carry out the overwrapping glue gum tree, cut its top surface with 1 / 2S with ethylene Fen stimulation, you can get a moderate yield. Before cutting can be used high and low cut two-lane with ethylene abundance stimulate short-term tapping. High-cut surface excitability excision will lead to a significant increase in latex production and relatively lower dry content. Long-term high-cut plastic cutting system long-term plastic ratio is relatively high.
