摘 要:为提高马尾松采脂效率,2013-2018年在江西吉安采用不同采脂刺激剂和不同采割频率对成熟马尾松林开展采脂试验。结果表明,促进型采脂刺激剂对马尾松的松脂产量具有明显促进作用,pH值为3~4的弱刺激型采脂刺激剂对马尾松采脂量促进效果最佳,增产率可达50%~60%;马尾松单株割沟频率不宜过高,以2~3天割1刀为宜;施用弱刺激型刺激剂,采用3天割1刀的低频割沟,可明显提高资源的利用率,提高采脂效率,提升采脂收益。In order to improve the efficiency of Pinus massoniana resin tapping,a experiment was carried out in the mature P.massoniana forest using different resin tapping stimulants and different harvesting frequencies in Ji′an,Jiangxi from 2013 to 2018.The results showed that the resin tapping stimulants had a significant effect on the pine resin production of P.massoniana,the weak stimulation type resin tapping stimulant with pH value of 3~4 has the best effect on promoting resin yield and the yield increase rate,which can reach 50%~60%.The frequency of obtaining resin should not be too high.It was appropriate to execute harvesting every 2 to 3 days.Using weak stimulation type resin tapping stimulant and low-frequency harvesting(once every 3 days),which can significantly increase resource utilization,and improve the efficiency and the revenue of liposuction.
