摘要
黄连作为一种重要的中药材,在中医药体系中具有不可替代的地位,且其药用历史源远流长。然而,随着黄连种植年限的延长,连作障碍日益凸显,对黄连的产量与品质构成了严重威胁,进而影响了整个黄连产业的稳健发展。本文深入探讨了黄连连作所带来的潜在危害,详细分析了连作障碍形成的深层原因,并针对性地总结了一系列切实可行的缓解措施。研究表明,土壤理化性质的逐渐劣化、土传病虫害的不断加剧,以及黄连自身的化感自毒效应,是导致连作障碍的三大主导因素。这些因素的产生与黄连、土壤及微生物之间的复杂交互作用密切相关,因此,应从优化栽培措施,落实土壤微环境修复,加速抗性品种选育一系列措施综合管理,进而促进黄连的高质量发展。
As an essential traditional Chinese medicinal material,Huanglian(Coptis chinensis Franch.)holds an irreplaceable and significant position in the system of traditional Chinese medicine,boasting a long history of medicinal use.However,with the prolongation of Huanglian cultivation years,the obstacles of continuous cropping have become increasingly prominent,posing a severe threat to its yield and quality,thereby affecting the steady development of the entire Huanglian industry.This paper delved into the potential hazards arising from the continuous cropping of Huanglian,comprehensively analyzed the underlying causes of these cropping obstacles,and summarized a series of practical and feasible mitigation measures accordingly.Research indicated that the gradual deterioration of soil physical and chemical properties,the intensification of soil-borne pests and diseases,and the allelopathic autotoxicity of Huanglian itself were the three primary factors leading to continuous cropping obstacles.The emergence of these factors were closely related to the complex interactions among Huanglian,soil,and microorganisms Therefore,we should optimize cultivation measures,implement soil microenvironment restoration,and accelerate the comprehensive management of resistant variety breeding,so as to promote the high-quality development of Huanglian.
