南繁作物生物安全现状及对策

Present Situation and Countermeasures of Crop Biosafety in the Nanfan Area

南繁区位于中国海南省,作为中国农作物繁殖和育种的重要基地,其在水稻、玉米等农作物良种繁育上具有不可替代的地位。然而,随着近几年来南繁育种工作的迅速发展,各地与海南岛之间农作物种子的调运日益频繁,种子来源于全国,又走向全国,为有害生物的传播提供了快速通道。因此确保南繁生物安全对打造“南繁硅谷”、保障我国种业健康发展有着重大意义。从南繁生物安全现状、当前南繁生物安全管理存在的问题等方面进行剖析,并针对南繁有害生物防控提出对策建议,为南繁基地生物安全管理提供参考。

The Nanfan(propagation and breeding activities in the tropical south of Hainan)base,located in Hainan,China,is an important base for seed production of desirable crop cultivars in China,and plays an irreplaceable role in the breeding of improved varieties of rice,corn and other crops.However,with the rapid development of seed production in Hainan in recent years,the transportation of crop seeds between the mainland and Hainan Island has increased frequently.The seeds come to Hainan from the most parts of the country and are then transported from Hainan to the most parts of the country after they are produced,providing a fast channel for the spread of pests.The crop biosafety in the Nanfan areas is of high significance in building the Nanfan areas as a"Nanfan Silicon Valley"and ensuring the healthy development of crop seed industry in China.The present developments of crop biosafety in the Nanfan areas were described,and the problems existing in the current biosafety management were analyzed,based on which were put forward some suggestions for the control and prevention of the pests in the Nanfan areas in order to provide reference for the biosafety of crops in the Nanfan areas in China.
