南药大品种穿心莲无公害栽培技术体系探讨

穿心莲（Andrographis paniculata）是我国传统中药材，主要种植在我国华南地区，市场需求量近年呈现稳中递增趋势，然而穿心莲药材生产过程中一直存在生产无序、农残及重金属含量超标等问题，开展无公害种植是解决该问题的有效手段，同时也是现阶段中药材种植产业的发展方向。为了指导无公害穿心莲种植，生产出高品质的中药材，本文依据本课题组多年研究结果，结合穿心莲药材研究现状，建立了穿心莲药材无公害精细栽培技术体系，包括精确的栽培选地、系统的土壤改良、科学的无公害种植模式及高效的病虫害综合防治技术等，帮助解决农残及重金属含量超标等问题。本文为穿心莲药材无公害精细化栽培提供了参考。

Research on Pollution-free and Technical Regulations of Andrographis Paniculata

Andrographis paniculata is a traditional Chinese herbal medicine with a wide cultivation in south China. Themarket demand has been increasing steadily in recent years. However, there are problems such as disordered production,pesticide residues and heavy metal content in the process of Andrographis paniculata production. Pollution- freecultivation is an effective strategy to solve this problem, and it is also the development direction of the Chinese herbalmedicine planting industry at this stage. In order to guide the cultivation of pollution-free and high-quality Andrographispaniculata, this study established a pollution- free fine cultivation technology system of Andrographis paniculataincluding precise cultivation and site selection. In addition, soil improvement, scientific pollution-free planting mode andhigh- efficiency integrated pest control technology help solve problems such as pesticide residues and heavy metalcontent. This paper provides a reference for the pollution-free and fine cultivation of Andrographis paniculata.
