油桐是我固主要木本油料树种之一。油桐种仁含油率高达百分之六十以上。桐油是优良的干性油,具有干燥快,比重轻,有光泽,不传电,防潮、防锈、防腐等优良特性,是工业、农业和国防建设的重要原材料,也是我国出口的重要商品。增产桐油的途径有两条,一是扩大种植面积,二是提高现有林产量。这次我们到了波阳县莲花山垦殖场,经过实地调查,认为杉桐混交大有前途,它是扩大油桐种植面积增产桐油的一种有效办法。
Tung is one of the main woody oil tree species that I solidify. Tung oil seed oil rate as high as sixty percent or more. Tung oil is an excellent dry oil, with the advantages of fast drying, light weight, luster, no transmission, moisture resistance, rust prevention and anti-corrosion. It is an important raw material for industrial, agricultural and national defense construction as well as an important commodity for export in China. There are two ways to increase tung oil: one is to expand the planting area and the other is to increase the existing forest output. This time we went to Lianhua Mountain reclamation farm in Boyang County. After field investigation, we believe that there is a promising future for the growing of the fir mixed tree, which is an effective way to increase the planting area of the tung tree and increase the production of tung oil.
