山(shan)(shan)陽(yang)龍須草(cao)(cao)(cao)葉(xie)狹線形,絲象(xiang)龍須而得名。山(shan)(shan)陽(yang)龍須草(cao)(cao)(cao)為多年生禾(he)本科纖維類植物,主要生長在丘陵山(shan)(shan)地(di)的石巖地(di)區,喜溫(wen)趨陽(yang),耐瘠(ji)薄,抗干旱,葉(xie)細長,軟韌(ren),是草(cao)(cao)(cao)制(zhi)工藝品和高級(ji)紙漿的上好原料,當地(di)群眾(zhong)稱其為“寶草(cao)(cao)(cao)”。
“少時青青老來黃(huang)七搓(cuo)八扭結(jie)成雙。春打(da)草(cao)鞋走(zou)山路夏編(bian)(bian)涼席鋪軟(ruan)床(chuang)。秋織蓑衣遮風(feng)雨,冬擰(ning)繩索套麝香(xiang)。更喜姑(gu)娘手藝巧,精制(zhi)草(cao)編(bian)(bian)銷遠洋。”這首在山陽縣廣為流傳的歌謠,唱(chang)出了商州“三寶”之(zhi)一龍(long)須草(cao)的用途。
山陽(yang)(yang)龍(long)須草的產地(di)位(wei)于陜西(xi)省商(shang)洛市山陽(yang)(yang)縣(xian)(xian),這里的龍(long)須草長(chang)達一米,是(shi)一種很理想的纖維資源(yuan),本色金黃,有光澤,且(qie)易染色。它(ta)系野生(sheng)之物(wu),山陽(yang)(yang)人民采取草籽繁殖和分根栽培(pei)的辦(ban)法(fa),大力(li)發展(zhan),全(quan)縣(xian)(xian)各地(di)均有分布,年(nian)產量干噸(dun)左右。
山(shan)陽龍(long)(long)(long)(long)須(xu)草(cao)的(de)(de)命名還有個(ge)美麗的(de)(de)故事。傳(chuan)說中華民(min)族的(de)(de)始祖黃(huang)帝(di)統一華夏后,教民(min)耕種,他遍嘗白草(cao),探索草(cao)性,正當他跋山(shan)涉(she)水找(zhao)到繁殖力(li)最強的(de)(de)生長在(zai)商州境內的(de)(de)龍(long)(long)(long)(long)須(xu)草(cao)時,天空突(tu)來玉龍(long)(long)(long)(long),傳(chuan)玉帝(di)圣旨,說黃(huang)帝(di)勞苦(ku)功高(gao),封為(wei)天皇(huang),令其(qi)速回(hui)天宮。人(ren)們(men)不舍(she)黃(huang)帝(di)離去,苦(ku)苦(ku)抓(zhua)住龍(long)(long)(long)(long)須(xu)不放。但午時三刻已到,玉龍(long)(long)(long)(long)騰空而去,人(ren)們(men)手抓(zhua)的(de)(de)龍(long)(long)(long)(long)須(xu)全然變成了金色的(de)(de)龍(long)(long)(long)(long)須(xu)草(cao),惠澤當地(di)百姓。
