湿地松中长期化学采脂

Mid and Long-team Resin Tapplng of Pinus elliottii by Chemical Method.

湿地松采脂强度在４０％割面负荷率和２５ｃｍ以下的下降面，采用食用漂白粉精片液和增产灵２号＋碳酸氢铵及乙烯利＋松针汁化学采脂技术，分别比常法采脂单株年平均产脂５．３２６ｋｇ提高１３．６５％，２２．２７％和３１．００％，而且对松脂及其产品松香、松节油质量和林木生长都没有影响。

Three kinds of chemica mnethods,chlorinated lime,phenoxyaceticacid + ammonium bicarbonate,and cthrel + pine needlc juice,were used inresin tapping of Pinus elliottii at 40% face load and below 25cm cut,resultingthat annual single-plant oleoresin yield increased by 13.65%,22.27% and31.00% compared with the traditional resin tapping method respectively.Applying those chemical methods,the bad influence of pinc resin and pro-duction in quality and tree growtli not be found.
