我国杂交水稻在技术、种质资源、科研水平都一直处于世界领先地位。然而,由于出口限制,检疫要求等原因造成杂交水稻“推而不广”的局面。导致我国杂交水稻“推而不广”原因:第一,我国杂交水稻品种不能适应当地气候条件。第二,我国对杂交水稻种子的出口有着非常严格的政策性限制。第三,政策制约和贸易壁垒。 China’s hybrid rice technology, germplasm resources, scientific research level has been in a leading position in the world. However, due to export restrictions, quarantine requirements and other causes of hybrid rice “push rather than wide” situation. Lead to hybrid rice in China “push rather than wide ” Reasons: First, the hybrid rice varieties in our country can not adapt to the local climatic conditions. Second, China has very strict policy restrictions on the export of hybrid rice seeds. Third, policy constraints and trade barriers.
