年产一亿吨 ，为什么土豆在中国当不了主食？ | The Potato Paradox in China

Описание: 全球有13亿人靠土豆续命 。欧洲人把它当“第二块面包” ，一年能造掉上百公斤 。但在中国，它死活融不进大米白面的主食圈子，只能拿来炖牛腩、炒土豆丝 。
这不是因为咱们挑食，而是因为土豆天生自带生存硬伤 。
它含水高达80%，放几天就发芽腐烂，根本没法像小麦那样长期囤积 。
如果硬要把它做成土豆粉，成本比面粉贵两倍以上 。
更要命的是，它自己留种还会病毒退化，产量断崖式下跌 。

Globally, 1.3 billion people rely on potatoes for survival. Europeans treat it as "second bread" , consuming up to 100 kilograms per person annually. But in China, it simply cannot break into the staple circle of rice and wheat; it's relegated to beef stews and stir-fries. This isn't about picky eating; it's because the potato comes with fatal biological flaws. With up to 80% water content, it rots or sprouts quickly and can't be hoarded long-term like wheat. Processing it into flour costs more than twice as much as wheat flour. Worse, if farmers save their own seeds, the potatoes suffer from rapid viral degradation, causing yields to plummet.
