近年来,东南亚各植胶国家对扩大树皮利用高度的要求日益紧迫,不少国家由于割胶强度太大,耗皮太多,使1.5米以下的树皮不够周转;加之各国普遍推广乙烯利,高部位树皮采用低强度采胶加刺激剂,不仅产量与低部位相当,而且比传统的阴刀割胶技术劳动强度大大减轻,较易为胶工所接 In recent years, the planting countries in Southeast Asia to expand the use of bark height requirements increasingly urgent, many countries due to the tapping strength is too large, too much skin, so that less than 1.5 meters of the bark is not working; coupled with the general promotion of ethephon in various countries, High parts of the bark using low-intensity plastic add stimulants, not only yield and low parts quite, and labor-saving than the traditional Yam tapping technology greatly reduced, easier for the plastic workers connected
