远志栽培现状及推广前景分析

采用实地访问、调查取样结合文献考查的方法,调查我国远志现有栽培县市的地理位置、生态环境、栽培品种、管理技术、栽培现状、经济效益等。结果表明,远志栽培集中在山西运城、临汾地区,其余省份及地区均只是零星种植。全国远志栽培面积缩减严重,无统一优良品种,栽培管理技术各异。过度的集中栽培,过长时间的连作致使主产区病害频发,所产药材品质下降。全国多地均适合远志栽培,故推广远志栽培就区域发展方面是可行的,也是必要的。远志国内外市场较大,且种植经济效益高,发展远志栽培,是农民增收和增加出口创汇的好选择。山西省农业科学院经济作物研究所建有全国野生及家种资源最全的远志资源库,并育出晋远1号、晋远2号等一系列优质品种。经过多年实践研究,总结制定了因地制宜、规范科学的栽培管理技术,为远志农业生产提供了强有力的科技支撑,远志栽培推广也就有了坚强的技术后盾。

Analysis of Cultivation Situation and Popularization Prospect of RADIX POLYGALAE

Field investigation was carried out to research the geographical location, ecological environment, cultivated varieties, management technology, cultivation status and economic benefits of RADIX POLYGALAE in different counties and cities of China.Result showed that RADIX POLYGALAE was cultivated mainly in Yuncheng and Linfen of Shanxi Province , and only a small amount was planted in other areas and prov-inces.Cultivation area of RADIX POLYGALAE reduced seriously in China , with neither unified good varieties nor cultivation management tech-niques.There were frequent diseases and quality decline of medicinal materials due to excessive cultivation and long continuous cropping .Inves-tigation also found out that there were many regions suitable for RADIX POLYGALAE cultivation , so it was feasible and necessary to promote RADIX POLYGALAE cultivation in the angle of regional development .RADIX POLYGALAE had huge domestic and foreign markets with high e-conomic benefits.Therefore, it was a good choice to use RADIX POLYGALAE to increase the farmers'income and to earn foreign exchange through exports.Institute of Industrial Crop of Shanxi Academy of Agricultural Sciences had the most complete RADIX POLYGALAE resources , nurtured Jinyuan 1, Fenyuan 2 and a series of high-quality varieties.After years of practice and study, scientific cultivation and management technology was established according to local conditions , which provided strong technology support for agricultural production of RADIX POLYG-ALAE, and provided strong technical support for the extension of RADIX POLYGALAE.
