茶用菊花产业概况及连作障碍研究进展

Research Progress on Tea-applied Chrysanthemum Industry and Continuous Cropping Obstacles

中国是菊花的原产地,自古以来就有饮用菊花茶的习俗。当前茶菊市场发展迅速,茶菊品种多样,种植地广泛。虽然各茶菊品种、生长特性不尽相同,但普遍均有连作障碍,这对当地菊花产量和品质均有不小的影响。该研究整理了全国茶用菊花种植概况,分析菊花连作障碍的原因为土壤微环境的改变,包括菊花化感自毒物质作用、土壤微生物群落变化、理化性质及酶活性变化;并提出通过选育优良品种、改良耕作模式两大方面缓解菊花连作障碍,旨在更好地促进茶菊产业的可持续发展。

China is the origin of chrysanthemums and has long custom of drinking chrysanthemum teaapplied.At present,the tea-applied chrysanthemum market is developing rapidly,the tea-applied chrysanthemum varieties are diverse,and the planting areas are wide.Although different tea-applied chrysanthemum varieties and growth characteristics differ,there are generally continuous cropping obstacles,which have a significant impact on local chrysanthemum yield and quality.The general situation of chrysanthemum planting in China were summarized,and the causes of continuous cropping obstacles were analyzed,the changes of soil microenvironment,including the effects of allelotoxic substances,changes of soil microbial community,physical and chemical properties and enzyme changes of chrysanthemum.And proposed measures to alleviate the obstacles of continuous chrysanthemum cultivation through breeding excellent varieties and improving cultivation modes,aiming to better promote the sustainable development of the tea-applied chrysanthemum industry.
