川芎无公害栽培技术体系探讨

川芎为著名川产道地药材,为临床常用中药,栽培历史悠久,但川芎在栽培过程中仍存在盲目引种、苓种繁育不规范、病虫害严重等问题,尤其农残和重金属镉超标问题一直未得到有效解决,严重响川芎产业可持续发展。开展无公害栽培技术研究是保障川芎产业可持续发展的有效途径之一,同时也是现阶段中药材生产的发展方向。本文基于课题组基地生产数据,结合国内其他基地成功经验及文献调研,构建了川芎无公害栽培技术体系,该体系包括基于GIS技术基地选址、土壤综合改良、良种的选育、合理施肥、病虫害综合防治等,为解决川芎镉超标问题提供了新途径,同时可促进川芎品质提升和产业可持续发展。

Discussion on Pollution-free Cultivation Technology System of Rhizoma Ligustici Chuanxiong

Rhizoma Ligustici Chuanxiong is one of the well-known medicinal materials located in Sichuan origin.It is a traditional Chinese herbal medicine commonly used in clinic with a long history of cultivation.However,some problems still exist in the production of Rhizoma Ligustici Chuanxiong,such as blind introduction and non-standard breeding of Rhizoma Ligustici Chuanxiong,serious diseases and pests.Especially,the problem of pesticide residue and cadmium exceeding the standard have not been effectively solved,which seriously affects the sustainable development of Rhizoma Ligustici Chuanxiong industry.The effective way to ensure the sustainable development of Rhizoma Ligustici Chuanxiong industry is to carry out the research of pollution-free cultivation technology,and it is also a developing direction for the production of traditional Chinese medicine at present.Based on the production data of base and combind with the successful experience of other bases in China and literature investigation,this paper showed the pollution-free cultivation technology system of Rhizoma Ligustici Chuanxiong.The system includes site selection base on GIS (Geographic Information System) technology,comprehensive soil improvement,breeding of improved varieties,rational fertilization,integrated control of diseases and pests,etc.It can provide a new way to solve the problem of excessive cadmium and scientifically guide the cultivation of Rhizoma Ligustici Chuanxiong without pollution,improve the quality,and promote the sustainable development of Rhizoma Ligustici Chuanxiong industry.
