大家好，我是付道林。一晃8年时光，很想念大家，也很想念这个舞台。2017年首次来CC讲坛，我还在 美国工作，今天，我是山东农业大学的一员，也是泉脉农业的创始人。回到祖国、挽起裤腿、深耕农 田，不为别的，就是为了我心中的恋人，杂交小麦。 大家知道，小麦很重要，很多人从小吃小麦长大。全球范围内，超过1/3的人口依赖小麦生存。那么， 如何让小麦变得更重要？如何让小麦养活更多的人口？这是我们所有农业科技工作者，都关心的问题。 杂交种的应用呢，在粮食增产中发挥了重要的作用。以玉米为例，杂交种的商业化应用已有近百年的历 史。在此过程中，杂交种的应用带来了至少6倍单位面积产量的提升。以至于到了今天，全球30多亿亩 的玉米，几乎100%采用杂交种。 杂交种的本质是利用杂种优势。那么，什么是杂种优势呢？就是杂交种比父母本都优秀的现象。如图所 示，杂交种可以是发芽快、个头高、结实多等各种表现。 听到这里，大家可能会想，杂交种既然这么好，是不是所有的粮食作物都广泛地应用了杂交种呢？其实 不然，在我国三大粮食作物中，玉米100%普及，水稻50%普及，但小麦的应用还不到1%。国际上，玉 米也是100%，小麦仍不足1%。 专题：2025 ...
