一.產品介紹
山(shan)陽(yang)九(jiu)眼蓮(lian)(lian)，已有500年(nian)栽(zai)植歷史。據(ju)傳，明(ming)成化年(nian)間，由“下湖(hu)人(ren)”帶來山(shan)陽(yang)。受(shou)山(shan)陽(yang)獨(du)特(te)自然(ran)環境影響，所產(chan)藕(ou)橫切面以髓(sui)為(wei)中心，均勻(yun)分布9個氣腔，比湖(hu)北白蓮(lian)(lian)多1-2個，故稱九(jiu)眼蓮(lian)(lian)。相傳，山(shan)陽(yang)九(jiu)眼蓮(lian)(lian)曾(ceng)為(wei)貢(gong)品(pin)上貢(gong)朝廷(ting)；人(ren)們常以“色白質脆(cui)味(wei)香甜，好菜要數(shu)九(jiu)眼蓮(lian)(lian)”來稱頌山(shan)陽(yang)九(jiu)眼蓮(lian)(lian)。1985年(nian)，山(shan)陽(yang)詩人(ren)陳文彥作詩一(yi)首(shou)贊(zan)山(shan)陽(yang)特(te)產(chan)九(jiu)眼蓮(lian)(lian)：色白質脆(cui)味(wei)香甜，山(shan)陽(yang)特(te)產(chan)九(jiu)眼蓮(lian)(lian)。淡水(shui)芙蓉堪稱羨，沃(wo)泥佳藕(ou)更值(zhi)錢。
二.自然生態環(huan)境(jing)和人文歷史(shi)因素
1、土(tu)(tu)(tu)(tu)(tu)壤(rang)地(di)貌(mao)情況：山陽縣屬(shu)秦嶺南坡中、低山區地(di)形結構(gou)，境(jing)內群山林(lin)立(li)，溝壑縱橫(heng)，北(bei)部的(de)流嶺、中部的(de)鵑(juan)嶺、南部的(de)鄖嶺三大山脈走向東西、橫(heng)斷(duan)南北(bei)，構(gou)成“三山夾(jia)兩川”的(de)嶺谷地(di)貌(mao)。土(tu)(tu)(tu)(tu)(tu)壤(rang)垂(chui)直地(di)帶性分布著(zhu)水稻(dao)土(tu)(tu)(tu)(tu)(tu)、潮土(tu)(tu)(tu)(tu)(tu)、淤(yu)土(tu)(tu)(tu)(tu)(tu)、紫色(se)土(tu)(tu)(tu)(tu)(tu)、褐土(tu)(tu)(tu)(tu)(tu)、黃(huang)棕土(tu)(tu)(tu)(tu)(tu)、棕土(tu)(tu)(tu)(tu)(tu)七種類型。土(tu)(tu)(tu)(tu)(tu)壤(rang)pH值6.0-7.5，土(tu)(tu)(tu)(tu)(tu)壤(rang)孔隙度50-55%。肥力(li)中等，有機質含(han)量1.5%，全氮70mg/kg，速(su)效磷30mg/kg，速(su)效鉀120mg/kg。
2、水(shui)(shui)文情況(kuang):山(shan)陽(yang)境(jing)內河(he)流(liu)屬長(chang)江(jiang)水(shui)(shui)系漢江(jiang)支流(liu)，河(he)網密度(du)(du)為(wei)1.2公(gong)里/平方(fang)(fang)公(gong)里，水(shui)(shui)資(zi)源(yuan)極為(wei)豐(feng)富(fu)。全(quan)縣有(you)金錢河(he)、銀花(hua)河(he)、謝(xie)家河(he)等7條主要河(he)流(liu)，水(shui)(shui)庫4座(zuo)。河(he)流(liu)流(liu)長(chang)共計(ji)158公(gong)里，流(liu)域面積共計(ji)3400平方(fang)(fang)公(gong)里。境(jing)內總徑流(liu)量14.47億(yi)立方(fang)(fang)米，總畜(chu)水(shui)(shui)量432萬立方(fang)(fang)米。河(he)流(liu)水(shui)(shui)源(yuan)主要來自天然降水(shui)(shui)，其(qi)次(ci)為(wei)山(shan)澗泉(quan)水(shui)(shui)。河(he)流(liu)平時清澈見底、汛期洪水(shui)(shui)猛增。地(di)(di)(di)下水(shui)(shui)主要由(you)降水(shui)(shui)和(he)地(di)(di)(di)表水(shui)(shui)入滲補給，又以(yi)泉(quan)水(shui)(shui)形成出露，排(pai)泄于河(he)流(liu)，轉化(hua)為(wei)地(di)(di)(di)表水(shui)(shui)。地(di)(di)(di)下水(shui)(shui)和(he)地(di)(di)(di)表水(shui)(shui)水(shui)(shui)質良好、礦化(hua)度(du)(du)小于1克/升的重碳酸鹽淡水(shui)(shui)，pH值5.7－8.5，是理想的工農業生產(chan)和(he)生活用水(shui)(shui)，適合九眼蓮生長(chang)。
