　　中新網(wǎng)3月20日電據(jù)外媒20日?qǐng)?bào)道，意大利南部盛產(chǎn)橄欖油的普利亞地區(qū)遭遇植物病菌侵襲，為防止病菌擴(kuò)散至其他地區(qū)，歐盟下令當(dāng)?shù)乜撤ス?100萬(wàn)棵橄欖樹(shù)。

　　當(dāng)?shù)孛考s年生產(chǎn)1100萬(wàn)噸橄欖，產(chǎn)量占意大利全國(guó)1/3，更是部分頂級(jí)橄欖油的原材料。此次橄欖樹(shù)被大量砍掉，恐怕會(huì)使全球橄欖油供應(yīng)量銳減，令價(jià)格飆升。

　　據(jù)報(bào)道，普利亞南部的薩倫托約100萬(wàn)棵橄欖樹(shù)受“葉緣焦枯病菌”感染。這種病菌最初是在美洲被發(fā)現(xiàn)，由蚜蟲(chóng)傳播，會(huì)導(dǎo)致植物枯萎且無(wú)法結(jié)出果實(shí)，會(huì)感染橄欖樹(shù)、葡萄樹(shù)、杏仁樹(shù)等。
