大黄具有悠久的药用历史。由于野生大黄对生长环境要求严苛，加之人为采挖等影响，导致大黄野生资源急剧下降。现阶段大黄资源以人工栽培为主，由于栽培地区广，种植管理不规范、农药滥用等问题导致大黄药材品质降低。为解决以上问题，本文对大黄无公害种植技术进行探讨，内容包括基于GMPGIS的大黄无公害种植地精准选址、土壤改良、优质种子选育、种苗繁育、合理施肥以及病虫害综合防治。该体系可为大黄无公害种植提供指导。

Rhubarb has a long history of drug use in China. Due to the harsh environment for the growth of wild Rhubarb and the influence of artificial mining, the wild resources of Rhubarb have declined sharply. At present, the resource ofRhubarb is mainly based on artificial cultivation. The wide cultivation, nonstandard management, and abused pesticides,lead to the quality decline of Rhubarb. To solve the problems above, this paper discusses the pollution-free plantingtechniques of Rhubarb, including the precise site selection based on GMPGIS, soil improvement, high-quality seedsbreading, seedling breeding, rational fertilization and comprehensive pest control of Rhubarb. The system can provideguidance for pollution-free planting of Rhubarb.
