通过对四川出口杂交稻种生产基地进行调查研究,结合四川杂交稻种主要贸易对象国检疫准入要求,对四川出口杂交稻种有害生物进行风险分析,探讨四川出口杂交稻种非疫产地生产体系建设。确定重点关注的特定有害生物10种,包括细菌3种,真菌5种,线虫病害和害虫各1种。针对重点关注的有害生物,抓住制种基地产地检疫管理关键控制点,通过设立非疫产地,保障出口稻种的检验检疫质量。
Based on the investigation of the export hybrid rice seed production base in Sichuan and the quarantine requirements of major trading partners of Sichuan hybrid rice varieties, the risk analysis of the pests of hybrid rice varieties for export in Sichuan was conducted to explore the production system of the non-epidemic origin in Sichuan export hybrid rice Construction. Identify 10 species of pests of particular interest, including 3 species of bacteria, 5 species of fungi, 1 species of nematode diseases and 1 species of pests. Focusing on the pests of interest, grasping the key control points for the quarantine management of the origin of the seed production base and ensuring the quality of the inspection and quarantine of the exported rice seeds through the establishment of the non-epidemic origin.
