摘　　要：介绍了作者近年来对钻孔法采脂技术的试验情况和取得的初步结果。试验结果表明,在目前的技术条件下,马尾松钻一次孔其连续流脂时间最长为2d,不宜进行钻孔法采脂。湿地松钻一次孔其连续流脂时间最短为20～30d,最长可达80～100d,平均单株产脂量为294.1g。若按间隔60d钻一次孔计,平均产脂量为4～5g/(d·株),而同期常法采脂平均产脂量为17～19g/(d·株)。钻孔法采脂平均单株产脂量远比常法采脂低。This article introduced the relevant investigative circumstance and the acquisition result of borehole oleoresin tapping tests in recent years.According to the results,under the current technique term,for masson pine there is continuous oleoresin flowing for only 2 days in one borehole drilling period,and the borehole tapping is not suitable.However,for slash pine continuous oleoresin flowing lasted at least for 20 to 30 days,the longest is up to 80 to 100 days,with an average yield of the oleoresin 294.1 g per tree.The borehole tapping gave lower average oleoresin out puts 4 to 5 g a day camparing with 17 to 19 g a day with the common tapping in the same period for 60 days.
