铜仁地区山药的生物学特性及栽培技术

Biological Characteristics and Cultivation Technique of Dioscored spp in Tongren Region

为充分利用铜仁市的立体农业气候资源,加快特色蔬菜产业发展,贵州省铜仁市2004年引进长型(棍棒状)山药块茎作商品栽培并取得成功.在铜仁市以棍棒状山药作主栽品种,可采用顶芽繁殖法和山药果繁殖法,良种繁育用种量(用山药果繁育山药鼻子)50 kg/667m2山药果,商品块茎生产用种量150～200 kg/667m2,采用宽窄行栽培,栽植时间2-3月份,单行种植在3 000株/667m2左右,双行种植可提高到3 500～4 000株/667m2.

The tubers of Dioscored spp with a long shape introduced from Anshun city were successfully cultivated in Tongren city to speed up development of special vegetable industry.The paper introduces the biological characteristics of Dioscored spp with a long shape,the apical bud propagation method and aerial tuber propagation method.The aerial tuber weight for its propagation of high quality tubers is 50 kg/667m2 and the tuber weight for its production is 150～200 kg/667m2.The cultivation technique includes wide-narrow row cultivation pattern,sowing in February and March,3 000 plants/667m2 in single-row planting pattern and 3 500～4 000 plants/667m2 in double-row planting pattern.
