一、种子活力的概念种子活力不是种子生活力,也不是种子生命力。种子活力是五十年代初期国际上开始提出,七十年代在一些国家广泛地开展了研究并应用到生产上去的一个新的概念。种子就其本身来说,在农业生产上起到增产的作用,一是要种性好,二是要纯而不杂,现在又增加了一个因素,就是活力要大。种子生命力,生活力和活力是三个有区别的概念。种子生命力,简单地说就是种子的死和活。种子在生产中又经常是以大批的、群体的形态出现,所以有发芽力的概念,种子的发芽力就是生活力。 First, the concept of seed vitality Seed vigor is not the seed vitality, nor is the seed vitality. Seed vigor was originally introduced in the world in the early 1950s. In the 1970s, a new concept widely studied and applied in production in some countries was put forward. For its part, seeds play an increasing role in agricultural production. The first is that they have better species and the second is pure and not complicated. Now one factor is added, that is, vitality is greater. Seed vitality, vitality and vitality are three different concepts. Seed vitality, in short, is the seed’s life and death. Seeds are often produced in large quantities, groups of forms, so there is the concept of germination, seed germination power is vitality.
