一.產品介紹
山(shan)陽(yang)九(jiu)(jiu)(jiu)(jiu)(jiu)眼蓮，已(yi)有500年栽植(zhi)歷史(shi)。據(ju)傳，明成化年間，由(you)“下湖人(ren)”帶來(lai)山(shan)陽(yang)。受山(shan)陽(yang)獨特(te)自然環境影響，所產藕橫切面以髓為中心(xin)，均勻分布9個氣腔，比(bi)湖北白(bai)(bai)蓮多1-2個，故稱(cheng)九(jiu)(jiu)(jiu)(jiu)(jiu)眼蓮。相傳，山(shan)陽(yang)九(jiu)(jiu)(jiu)(jiu)(jiu)眼蓮曾為貢品(pin)上貢朝廷；人(ren)們常以“色(se)白(bai)(bai)質脆味香甜，好(hao)菜要(yao)數(shu)九(jiu)(jiu)(jiu)(jiu)(jiu)眼蓮”來(lai)稱(cheng)頌(song)山(shan)陽(yang)九(jiu)(jiu)(jiu)(jiu)(jiu)眼蓮。1985年，山(shan)陽(yang)詩人(ren)陳文彥(yan)作詩一(yi)首贊山(shan)陽(yang)特(te)產九(jiu)(jiu)(jiu)(jiu)(jiu)眼蓮：色(se)白(bai)(bai)質脆味香甜，山(shan)陽(yang)特(te)產九(jiu)(jiu)(jiu)(jiu)(jiu)眼蓮。淡水(shui)芙(fu)蓉堪稱(cheng)羨，沃泥佳藕更值(zhi)錢。
