千百年来马铃薯生产一直是用其块茎做“种子”进行无性繁殖的。无性繁殖有利于保持原品种的优良种性,便于栽培管理、生育期短,薯苗在发育的早期就具有较强的生活力,受外界不良环境的影响小,所以较易获得高产。可是既然如此又为什么要提出用种子生产马铃薯呢? 首先,看一下用种量。用薯块做种生产马铃薯用种量很高,一般每亩地用种薯100—150千克甚至更多。用种量大本身就提高了生产 For thousands of years, potato production has been clonally propagated with its tubers as “seeds.” Asexual reproduction is conducive to maintaining good varieties of the original species, easy to cultivation and management, short growth period, potato seedlings early in the development has a strong viability, less affected by the adverse external environment, it is easier to obtain high yield. But since then why the proposed production of potatoes seed it? First of all, take a look at the amount used. With potato tuberous species to do the production of high-volume potato, usually with 100-150 kilograms of seed per acre or more. With the kind of big increase in production itself
