山花椒(Zanthoxylum Schlninfolium Sled etzucc.)是经济价值较高的野生木本油料树种,种子富含油质,含油率达31.73—39.55%,出油率为20—30%,比大豆出油率高一倍多,油可食和工业用。油(米查)加工后可以做酱,也可作肥料和精饲料。其叶、根及果实均可入药,果皮除作调料和药用外,还含有百分之四的芳香油。其枝、干是不需干贮的易燃燃料,萌条可编织,侧根发达,是保土护坡的优良树种之一。山花椒在我市区分布很广,四县一区到处可见,据统计集中连片的就有十万亩左右。若把我市区现有山花椒资源保护利用起来,自然产量可达到一百三十多万斤,可出油三十二万斤左右,能解决八万多人的全年吃油问题(每年每人按四市斤计算)。山花椒虽然是经济价值较高的木本油料树种,但种籽产量还是很低的,岫岩县洋河公社有山花椒一万亩,一九七八年采收种子七万斤左右,平均亩产约七斤。弯沟大队的 Zanthoxylum Schlninfolium Sled etzucc. Is a wild woody oilseed species with high economic value. The seeds are rich in oil with oil content of 31.73-39.55% and oil yield of 20-30%, which is higher than that of soybean More than doubled, oil edible and industrial use. Oil (rice check) can be processed after the sauce, but also for fertilizer and concentrate feed. The leaves, roots and fruits can be used as medicine, peel addition to seasoning and medicinal, but also contains four percent of aromatic oil.

Mountain pepper is widely distributed in our city, four counties and one area can be seen everywhere, according to statistics there are about one hundred acres of contiguous pieces. If we use the resources of the existing mountain pepper in our city to protect and utilize it, the natural output will reach over 1.3 million kilograms and about 320,000 kilograms of oil will be produced, which can solve the problem of more than 80,000 people eating oil throughout the year Per person per four kilos). Although the pepper is the economic value of woody oilseed species, but the seed yield is still very low, Xiuyan County Yanghe commune Hill prickly ash acres, 1978 seventy thousand kilograms of seeds collected, the average Yield about seven pounds per mu.
