一、研究目的与意义马尾松(Pinus massoniana Lamb.)是我国主要采脂树种,产脂量较高,占全国松脂总产量的90％以上。目前常法采脂劳动生产率低,一个采脂农民在一个采脂季节内一般只生产松脂2-3吨,与国外先进国家相比差距较大。因此,迫切需要开展新的化学采脂技术研究,以提高松脂产量和劳动生产率。我们曾用过53种有关化学药物、植物生长刺激素、生物刺激剂对马尾松进行中长期(采脂年限为10-15年)化学采脂筛选试验,要求选择增产松脂效果好,安全无毒和不损害松树生长的化学采脂刺激剂。筛选结果表明,应用亚硫酸盐酒糟醪液(以下简称“醪液”)刺激马尾松增产松脂效果较为显著,三年试验结果,平均比常法采脂增产30％左右。
First, the purpose and significance of the study Pinus massoniana Lamb (Pinus massoniana Lamb.) Is China’s main resinous species, fat content is high, accounting for more than 90% of the country’s total output of pine resin. At present, the labor productivity of fat-collecting is low. A fat-picking peasant usually produces 2-3 tons of rosin in a picking season, which is far behind that of foreign advanced countries. Therefore, there is an urgent need to carry out a new chemical liposuction technology research to improve rosin yield and labor productivity. We have used 53 kinds of chemical drugs, plant growth-stimulating hormone, bio-stimulants on the long-term (lipid-bearing years of 10-15 years) chemical peptide screening test of masson pine, we need to choose a good effect of increasing yield of pine resin, safe and non-toxic And chemical lipophilic stimulants that do not impair the growth of the pines. The screening results showed that the application of sulfite distiller’s grains mash (hereinafter referred to as “mash”) to stimulate Pinus massoniana pine oil yield more significant effect, the three-year test results, an average of about 30% increase than the normal method of fat.
