(壹)基本情况陽新柑桔栽培已有200年以上歷史,栽培总面積約2,000畝,总株数約50,000株,1954年以前年產10,000—20,000担,〔一〕分布于江边的新合鄉和海口鄉,丘陵地区的新建鄉和柏林鄉,山区的龍潭鄉和筠山鄉等6个鄉;而以新合鄉和龍潭鄉出產为多。抗寒丰產的迟桔占栽培总株数90％以上,抗寒早熟的早桔約占5％;余为柑子、縐紋皮柑,甜橙,南丰桔等。柑桔收入占各鄉重点農業合作社总收入50—70％,由于1955年元月絕对低溫达到—8.6℃,冷凍賡續35天,且大凍前亢旱3个多月綜合的構成严重的凍害。虽然实生苗生活力强,但凍害普遍嚴重;龍潭鄉迟桔,早柑,桔子等凍死50—70％,減產90以上,新合鄉100多株甜橙幾乎全部凍死;就9个重点農業合作社統計,〔二〕迟桔27,555株凍死17.5％,早桔1,305株凍死16.8％;一般非3—5年內所能恢复。
(一) Basic Situation Yangxin citrus cultivation has a history of more than 200 years, with a total cultivated area of about 2,000 mu and a total number of about 50,000 plants.
