      【转基因科普动画】谣言9:转基因作物能增产是骗人的

      2018-04-22 20:43 | 作者:基因农业网 | 标签:转基因科普动画 标签:谣言真相

      真相:转基因农作物的增产效果是客观存在的。

      现阶段广泛商业化种植的转基因作物并不以增产为直接目的,有着更高产量和其他更优良特性的转基因作物,是下一代转基因作物研发的方向。

      农业上的增产与否受多种因素影响,转基因抗虫、抗除草剂品种能减少害虫和杂草危害,减少产量损失,加快了少耕、免耕栽培技术的推广,这实际起到了增产的效果。如巴西、阿根廷等国种植转基因大豆后产量大幅度提高;南非推广种植转基因抗虫玉米后,单产提高了一倍,由玉米进口国变成了出口国;印度引进转基因抗虫棉后,也由棉花进口国变成了出口国。
