摘　　要：湿地松(Pinus elliottii Engelem.)中长期化学采脂,通过23种刺激剂筛选和4个采脂季的研究,认为其中8号刺激剂效果最好。与常法采脂比较:松脂产量提高28.5％±4.6％;松脂、松香质量相同;长期使用增产稳定;采脂员经济效益提高25.7％;采脂林木材材积年平均生长量提高7.7％;林地综合经济效益提高22.3％。比不采脂林地提高2.26倍,是中长期化学采脂的有效刺激剂,可推广应用。23 stimulants were tested in mid- and long - term tapping of Pinus ellioltii in four tapping seasons. No.8 stimulant gave the best effects. Compared with the traditional wood tapping methods, the oleoresin yield-has been raised to 28.5%± 4.6%, the cconomic benefits of the tapping farmers, the composite benefits of forest land and the average increment in volume on tapping area have been increased by 25.7%, 22.3% and 7.7% /a, respectively. The overall economic contribution from the forest land has been increased by 77.3% compared with that from un-tapped forest land.
