采脂工艺和采脂技术的改进仍然是提高采脂生产率的最重要因素,因为从生物学上提高松林的产脂力目前在实践中尚奏效很少。国内外的松树采脂经验表明,只有依靠大规模地采用化学刺激剂刺激松脂形成和分泌,才能改善采脂生产的经济效果。下表表明了全苏联采用刺激剂采脂的平均效果。表中数字表明,用化学药品进行刺激可以显著提高劳动生产率、降低采脂的困难程度和成本,并从根本上加快了采脂原料基地的开 Improvements in greasing techniques and greasing techniques are still the most important factors in increasing the greasy yield, since biofueling to improve the lipid-producing capacity of pine forests is currently practically ineffective. Pine domestic and foreign experience in lipid-picking show that only by using large-scale chemical stimulant to stimulate the formation and secretion of rosin in order to improve the economic effect of the production of fat-picking. The table below shows the average effect of using stimulants in the whole Soviet Union. The figures in the table show that stimulating with chemical drugs can significantly improve labor productivity, reduce the difficulty of collecting lipids and cost, and fundamentally speed up the opening
