马尾松采脂新工艺、新工具及化学采脂的研究

STUDY ON STIMULANTS, HACK AND TECHNOLOGY FOR TAPPING PINUS MASSONIANA

介绍了广西昭平县的基本概况和松林资源现状,对马尾松的采脂方法、采脂工具进行了改革,论述了马尾松浅割薄修新工艺及其产生的社会效益和经济效益。还报道了短柄外向定位采脂刀,该刀具有轻便、提高劳动生产率等优点;应用塑料杯做受脂器,松脂含油量高、脂质重;应用“增产灵-2号”进行化学采脂,可增产松脂20％左右。

The general situation of pine resources of Zhaoping County,Guangxi and a reconstruction in tapping method and hack in this county are introduced with explainations of the 'Narrow and thin chipping', a new technology, as well as its outstanding social benefits.The reconstructed hack has a short handle and outside orientation controller. Its advantages are light weight, high labour productivity and low cost. Oleoresin collected in plastic cup con-tains more turpentine than that collected with nylon film,'No.2 Zengchanting' used as a stimulant for tapping can increase oleoresin by 20%than that without it.
