即使是所谓的随采随播也只是一个相对概念。事实上任何一批种子播种前都要经过储藏。从某种意义上说,不解决种子储藏问题,甚至人类早期社会的农业生产也不可能发展。许多树种有结实的大小年现象。不少省(区)已经建立比较大型的种子库。研究种子的储藏问题有着重要的实践意义。 Even the so-called companion companion is only a relative concept. In fact, any batch of seeds goes through storage before sowing. In a sense, it is impossible to solve the problem of seed storage and even agricultural production in early human society. Many species have a strong annual size. Many provinces (districts) have established relatively large seed banks. Studying the storage of seeds has important practical significance.
