植物油是人类生活中的必需品,也是重要的工业原料。目前植物油的生产状况远远满足不了四化建设和人民生活的需要。为了广开油源,寻找北方地区较为适宜的木本油料树种,我们从1979年以来,对我所现有240多个树种进行了观察记载和分析研究,发现过去一直被人们认为是观赏树种的榆叶梅,不仅具有很好的观赏价值,而且也是一种很有希望的油料树种。榆叶梅(prunus triloha Linde)为蔷薇科,桃亚属的落叶灌木或小乔木,高可达3—5米,多丛生。原产我国北部,以河北、山东、山西等省分布较多,其它省亦有栽植。榆林地区林研所于1969年从甘肃省兰州市引入,1975年作为绿篱栽植,现已大量结实。一、榆叶梅种仁的含油率及土法熬制:经对本所和北京两产地的榆叶梅种仁测定,榆叶梅种子的出仁率如表1。用于分析试样的种源,来自本所及北京。经用索氏 Vegetable oil is a necessity in human life and an important industrial raw material. At present, the production of vegetable oil far can not meet the needs of the four modernizations and people’s lives. In order to broaden the oil source and find more suitable woody oilseeds in northern China, we have observed and analyzed more than 240 tree species in our country since 1979 and found that in the past it was thought to be ornamental tree species Ulmus, not only has a good ornamental value, but also a very promising species of oilseeds. Prunus triloha Linde is a deciduous shrub or small tree of the genus Rosaceae and Peach, with clusters of up to 3-5 meters tall. Origin of northern China, Hebei, Shandong, Shanxi and other provinces are more distributed, but also other provinces planted. Yulin Lin Institute in 1969 from Lanzhou City, Gansu Province introduced in 1975 as a hedge planting, is now a large number of strong. First, the Yam Yeme seed kernel oil content and soil boiled: The Institute and the two producing areas of Beijing Yeme plum seed determination, Ye Yemei seed kernel rate as shown in Table 1. For the analysis of provenance, from the Institute and Beijing. After using Soxhlet
