本文系统总结了世界转基因作物以及中国转Bt基因棉花的种植现状,并从农田生态系统安全的角度提出转Bt基因作物种植存在的环境危害问题,重点指出我国转Bt基因棉花的大规模种植对根际生态系统的影响潜力;强调了转Bt基因棉花对根际生态系统的影响研究的必要性、复杂性和长期性,建议加大研究力度,尽快研究解决转Bt基因作物的生态危害问题。
This article systematically summarizes the present situation of transgenic crops in the world and the transgenic cotton plants in China, and puts forward the environmental hazards existing in transgenic Bt crops from the point of view of farmland ecosystem security. It points out that the large-scale planting of Bt transgenic cotton plants in China The potential of inter-Bt transgenic cotton is highlighted. The necessity, complexity and long-term nature of the study on the effects of transgenic Bt cotton on rhizosphere ecosystems are emphasized. It is suggested that greater efforts be made to study and solve the ecological hazards of Bt transgenic crops as soon as possible.
