榛子(Corylus heterophylla Fiseh)是我省珍贵的乡土油料树种,综合利用价值较高,榛仁含油50.6—54.4%,蛋白质16.2—23.6%,淀粉6.65%,碳水化合物16.5%,以及维生素等其它营养物质,榛仁出油率可达30%左右,相当于大豆出油率的二倍多,并且油香可食。榛仁味甜,细腻可口,糖果点心也广泛使用。在近一个世纪以来,国外把榛树发展到栽培经营,尤其是土耳其,面积为五万五千垧,年产36万吨,占世界总产量的61%,但在我国榛树均为野生。在文化大革命以前,有许多科研部门开展了栽培试验,为开发利用野生榛树打下了良好的基础。从我省来看,利用野生榛树发展油料生产,有利条件是很多的。
Corylus heterophylla Fiseh is a precious native oilseed species in our province with high comprehensive utilization value. Oil content of hazelnut is 50.6-54.4%, protein is 16.2-23.6%, starch is 6.65%, carbohydrate is 16.5%, and vitamins and other nutrients , Hazelnuts out of the oil rate of up to 30%, equivalent to more than twice the rate of soybean oil, oil and edible. Hazelnut sweet, delicate and delicious, sweets are also widely used. In recent centuries, hazel trees have been developed and cultivated in foreign countries, especially Turkey. With an area of 55,000 垧 and an annual output of 360,000 tons, it accounts for 61% of the world’s total output. However, hazel trees in China are wild. Before the Cultural Revolution, many scientific research departments carried out cultivation experiments, laying a good foundation for the development and utilization of wild hazel trees. From our point of view, the use of wild hazel to develop oil production, favorable conditions are many.
