长江中、下游地区番红花的高产栽培技术

番红花（ＧｒｏｃｕｓｓａｔｉｖｕｓＬ．）为灵敏类名贵药材．对番红花特征、特性及生育规律的观察和研究，并根据长江中、下游地区亚热带、温带季风的气候特点，提出球茎秋种夏收，露地越冬繁殖球茎：室内无土栽培，促使球室开花采收花柱，作两年生作物栽培．实施该技术后干花每公顷从原水平１１．７ｋｇ提高到１５ｋｇ左右，球茎有效繁殖倍数稳定在２倍左右．

THE HIGH YIELD CULTIVATION TECHNIQUE OF SAFRON FOR LOWER AND MIDDLE REACHES OF YANGTZE RIVER

Safron (Crocus sativus L.) is a rare medicinal herb. Based on the studies of characteristics and growth law of the plant, we put forward a high yield cultivation technique of Safron for a subtropical zone, the lower and middle reaches of Yantze River. The technique consists of cultivating the corms in autumn and haversting them in summer, breeding the corms in open fields for the winter, soilless cultivation in the house, and promoting the flowering of corms to get the styles for cultivating next year. The technique raises the output of dry flowers from 11 .7kg / hm2 to 15 kg / hm2.
