鎮(zhèn)平廣洋大棗栽培歷史悠久，在距今一千四百多年的《齊民要術(shù)》中就有記載。
      
    廣洋大棗其果呈長(zhǎng)圓形，果肉較厚，汁多酥脆，核小，皮薄，色鮮，久煮不爛，壓扁后短時(shí)間內(nèi)能復(fù)原，搖動(dòng)作響，所以又叫“廣洋圓鈴”。廣洋大棗果縱徑3.7 —4厘米，橫徑2.7—3厘米，鮮果最大單果達(dá)26—75克。據(jù)《傷寒論》記載，廣洋大棗有豐富的營(yíng)養(yǎng)價(jià)值和藥用價(jià)值。因此，廣洋大棗為鎮(zhèn)平三大寶之一（絲綢、玉器、廣洋棗），也是我國(guó)的名產(chǎn)。
      
    廣洋棗分為廣洋圓鈴和衍化圓鈴兩個(gè)品系、九個(gè)品種。即：大圓鈴、小圓鈴、圓鈴、長(zhǎng)吊圓鈴、紫味棗、早半月、九月寒等。廣洋大棗年產(chǎn)量一般在200萬(wàn)斤左右，是廣洋村群眾主要經(jīng)濟(jì)來(lái)源。
