据调查,牡丹江林区野生木本植物的种子或种仁含油率在1O×10~(-2)以上的就有约50种。这里就分布广、贮量多、株产高、易开发、含油率在20×10~(-2)以上的10余种野生木本油料植物简述如下:1 胡桃楸 Juglans mandshurica Maxim.落叶乔木;奇数羽状复叶;果实卵形,长3.5～7.5厘米,5～7个集生;果期8～9月,种仁含油58×10~(-2),是高级食用油或用于制肥皂或提制亚油酸。果实易采,采后去掉果肉和壳用压榨或浸出法取油。2 红松 Pinus koraiensis Sieb.et Zucc.常绿乔木;叶5针一束;球果大;圆锥状卵形,长达4厘米;种子倒卵状三角形,长1.2～1.6厘米、果期9～10月,种仁含油67.24×10~(-2)～68.27×10~(-2),是优良的食用及工业用油,可直接或脱壳后用压榨法取油。3 毛榛 Corylus mandshurica Maxim.落叶灌木;叶片广卵形或阔椭圆形,长6～10厘米,中上部常浅裂;坚果球形,径约1.5厘米,包于管状总苞内,常2～3个簇生。果期9～10月,种仁含油63.77×10~(-2),油可食用,去壳用压榨法取油。
According to the survey, there are about 50 species of seed or kernel oil of wild woody plants in Mudanjiang forest region with the oil content above 10 × 10 -2. More than 10 species of wild woody oil plants, which are widely distributed, large in reserve, high in plant production and easy to exploit, with an oil content above 20 × 10 -2, are summarized as follows: 1 Juglans mandshurica Maxim. Deciduous tree ; Odd pinnately compound leaves; fruit oval, 3.5 to 7.5 cm long, 5 to 7 connate; fruiting period from August to September, seed oil 58 × 10 -2, is a senior edible oil or for Made of soap or made of linoleic acid. The fruit is easy to adopt, remove the flesh and shell after harvesting, and extract it by squeezing or leaching method. Pinus koraiensis Sieb.et Zucc. Evergreen trees; leaves a pin 5; cones large; conical ovate, up to 4 cm; seeds obovate triangular, length 1.2 ~ 1.6 cm, the fruit of 9 ~ In October, the seed kernel oil was 67.24 × 10 -2 ~ 68.27 × 10 -2, which is an excellent food and industrial oil, which can be directly or after husking the oil by squeezing method. 3 Corylus mandshurica Maxim. Deciduous shrub; leaf blade broadly ovate or broadly elliptic, 6-10 cm long, often lobed in mid and upper; nut globose, ca. 1.5 cm in length, enclosed in tubular involucre, often 2 to 3 A cluster of students. Fruit from September to October, seed oil 63.77 × 10 ~ (-2), edible oil, husked with the oil extraction method.
