油橄榄是一种很有价值的木本油料树种,产油量很高,以每亩10株算,树龄20年左右的,一般年份每亩可产油33公斤,比大豆、花生亩产量均高(大豆亩产油9公斤,花生25公斤),油可食用,营养价值好,可治胃病和肝病,复榨油可做工业用油,果实亦可做罐头。油橄榄树极易栽培,但容易受节结病的为害,受害的油橄榄植株矮小,结果量降低,严重时整株死亡。这种病害可随苗木及其根际土壤运转而远距离传播。
Olive is a valuable woody oilseed species, high oil yield to 10 per acre count, the age of about 20 years, the average annual output of 33 kg per mu, higher than soybean, peanut yield per mu (Soybean yield 9 kg per mu, peanut 25 kg), oil edible, good nutritional value, can cure stomach problems and liver disease, oil press can be used as industrial oil, can also be made of canned fruit. Olea europaeus very easy to grow, but susceptible to node disease damage, victims of olive plant dwarf, the results decreased, the entire plant died in serious cases.
