我国茶叶在种植环节的质量安全问题及对策

概述了茶叶种植环节存在的茶叶质量安全类型及成因,探讨了应对技术措施和策略.茶叶农药残留、重金属和氟含量超标是目前茶叶质量安全的主要问题,产地环境不合格、农药肥料使用不当和茶叶采摘不合理是产生这些问题的重要原因.应对措施包括加强产地环境监控,改善茶园生态环境;加强生态防控技术,减少化学农药使用;加强替代农药和农药高效使用技术研究;加强肥料监管,努力提高肥料利用率;强化档案记录,建立产品质量追溯体系;完善茶叶生产技术规程和产品质量标准,加强宣贯力度.

Tea Safety Issues in Field Production in China and their Countermeasures

This paper outlined the kinds of tea quality issues during tea production in fields and their af- fecting factors and explored some of the control measures. The exceeding standard limits of pesticides res- idue and the heavy metal and fluorine content were the main tea quality issues. The disqualification of the environment of tea planting areas, improper use of pesticides and fertilizers, and unreasonable tea pluc- king standards were the main causes of these safety issues. The countermeasures would include strengthe- ning monitoring and improvement of the environment of tea planting areas, strengthening ecological con- trol measures to pests and diseases, reducing the use of chemical pesticides, strengthening the research and development of new pesticides and their efficient use technology, strengthening the fertilizer manage- ment and increasing their use efficiency, and establishing and strengthening the tea quality traceability system. Meanwhile, the tea production regulations and tea quality standards should be improved.
